About NetBackup Replication Director
Replication Director is the implementation of NetBackup OpenStorage-managed
snapshots and snapshot replication, where the snapshots are stored on the storage
systems of partnering companies. OpenStorage is a Veritas API that lets NetBackup
communicate with the storage implementations that conform to the API.
Replication Director uses the functions of the OpenStorage partners to perform the
following tasks:
■
To share disks so that multiple heterogeneous media servers can access the
same disk volume concurrently.
■
To balance loads and tune performance. NetBackup balances backup jobs and
storage usage among the media servers and disk pools.
■
To make full use of disk array capabilities, including fast storage provisioning
and almost unlimited storage.
■
To use as an alternative to off-site vaulting. Storage replication technology
provides an efficient means to send copies of user data (files, applications,
databases) to off-site storage as part of a disaster recovery plan.
Introduction
About NetBackup Replication Director
NetBackup stores snapshots of client data on the volumes that are available to the
storage server.
Snapshots represent a point-in-time of primary storage data as captured by the
storage hardware. NetBackup can then instruct the storage server to replicate the
snapshot from primary volumes to other volumes available to the storage server.
The snapshot can be replicated to multiple volumes within the storage server, or
to storage outside of the storage server, such as a tape device or other disk storage.
Replication Director can accommodate an assortment of scenarios to meet the
specific data protection needs of an organization.
Note: Replication is not supported for EMC VNX and Celerra at this time.
Replication Director offers a single NetBackup interface for end-to-end data
protection management for the following tasks:
■
Unified policy management.
Use the NetBackup Administration Console as the one, centralized backup
infrastructure to manage the lifecycle of all data.
■
Snapshot copy management.
Use NetBackup to manage the entire lifecycle of the snapshot. Replication
Director uses OpenStorage with a media server to access the storage server
volumes. No image can be moved, expired, or deleted from the disk array unless
NetBackup instructs the storage server to do so.
The instruction to perform the initial snapshot comes from an operation in a
NetBackup storage lifecycle policy (SLP). You can create one SLP that instructs
NetBackup to create the initial snapshot, to replicate the snapshot to several
locations, and to indicate a different retention period for each of the replications.
Additional instructions (or operations) can be included in the SLP that create a
backup from the snapshot, index the snapshot, and more.
■
Snapshot copy monitoring.
Use NetBackup OpsCenter to monitor the creation of each copy at each storage
location. OpsCenter provides extensive reporting on the entire replication
environment.
■
Global search and restore.
Recovery is available from any storage device in the environment that is defined
to NetBackup. This includes recovery from the primary copy or any replicated
copy on disk, or from any duplicated copy on disk or tape.

Introduction
About the roles of the Replication Director plug-ins
About the roles of the Replication Director
plug-ins
Replication Director uses an OpenStorage plug-in on the media server to
communicate with the disk array (through the storage server) and to make requests
to move data.
The OpenStorage partner hosts a software plug-in that allows communication
between NetBackup and the disk array.
Table 1-1 lists the plug-ins used by NetBackup and by the OpenStorage partners.
Table 1-1
Names of plug-ins used in Replication Director
Plug-in name
Installation location
NetApp Plug-in
for Veritas
NetBackup
The NBUPlugin communicates with the OnCommand Unified Manager.
For installation instructions, see the NetApp Plug-in for Veritas NetBackup Installation and
Administration Guide, available from the NetApp Support Site.
The default communication between the two plug-ins is to use encryption. A change can be made
to the NBUPlugin config file to disable encryption. The Encryption policy attribute has no impact
on the encryption between the plug-ins.
By default, the NetApp Plug-in for Veritas NetBackup uses IPv4, however the system can be
configured to use IPv6.
Note: The NetApp Plug-in for cDOT support (2.0) cannot be installed on the OnCommand Unified
Manager server, the master server, or any media servers. You should install the plug-in on a
separate Windows or Linux computer.
VNX NAS RD
NetBackup installs the plug-in by default; no separate installation is needed.
Software required to use Replication Director
Install NetBackup on all master servers, media servers, and NetBackup clients to
be used with Replication Director.

■
NetBackup naming conventions
■
How to configure a multi-NIC environment
Configuring the NetBackup Client Service
By default, the NetBackup Client Service is configured on Windows with the Local
System account. The Local System account lacks sufficient rights to perform
certain backup and restore operations.
For example, for NetBackup to access CIFS volumes, the account must be changed
from Local System to an account with access to the CIFS share.
To change the NetBackup Client Service logon account on a Windows computer:
■
Open the Windows Services application.
■
To change the logon account, stop the NetBackup Client Service.
■
Open the properties for the NetBackup Client Service.
■
Provide the name and password of the account that has the necessary
permissions. For example, change the logon to that of Administrator.
■
Restart the service.
If the logon property is not changed for the NetBackup Client Service, the policy
validation fails with status code 4206.
Additional configuration topics
NetBackup naming conventions
Situations in which the NetBackup Client Service logon
account requires changing
The following list contains situations in which the NetBackup Client Service logon
account needs to be changed:
■
To access CIFS storage for a storage unit.
■
To use UNC paths, the network drives must be available to the service account
that the NetBackup Client Service logs into at startup. You must change this
account on each Windows client that is backed up that contains data that is
shared with another computer.
■
During a snapshot: To have read access to the share for backup purposes and
write access during restores.
The account must be for a domain user that is allowed to access and write to
the share. To verify the account, log on as that user and try to access the UNC
path. For example: \\server_name\share_name.
■
For database agents and options, configure the service with a logon account
that has the necessary permission or privileges. See the documentation for your
agent or option for more information.
■
For the database agents that support VMware backups on a NetApp disk array,
configure the logon account to one that has access to the disk array.
NetBackup naming conventions
The following set of characters can be used in user-defined names, such as disk
pools and storage lifecycle policies:
■
Alphabetic (A-Z a-z) (names are case-sensitive)
■
Numeric (0-9)
■
Period (.)
■
Plus (+)
■
Minus (-)
Do not use a minus as the first character.
■
Underscore (_)
Note: No spaces are allowed.

Additional configuration topics
How to configure a multi-NIC environment
How to configure a multi-NIC environment
A NetBackup client can have multiple host names that correspond to multiple
Network Interface Cards (NICs). To access the snapshots using a particular NIC,
you must use the host name that corresponds to that NIC as a client name in the
NetBackup backup policy.
Ensure that the route to the filer follows the same interface that is defined as the
client name in backup policies.
Note: If the NIC information is not configured correctly, backup and restore jobs
may fail.
Example of a client that uses multiple NICs
Consider an HP-UX 11.31 host with the host name hp_nas.abc.xyz.com. This host
is configured as a client in a backup policy. This backup policy is intended to support
the NAS volumes which are mounted on the host. The host has multiple NAS
volumes mounted which are created on the filer with IP address 10.80.155.147.
Host hp_nas.abc.xyz.com has two NICs configured, as shown in Table 2-1.

Since the IP/subnet address of the filer does not fall under any routing entry defined,
network communication from the host happens using the default routing entry.

Additional configuration topics
How to configure a multi-NIC environment
As previously mentioned, the default route entry has the same interface (lan0) as
that of the entry corresponding to the client name hp_nas.abc.xyz.com (lan0).
Similarly, if there is an entry defined in the routing table explicitly for the subnet of
the storage system’s IP address, ensure that the same interface similarity exists.

Media
server
Select the media server to query the storage server. This is the media server
that is assigned the credentials for the storage server. Credentials allow the
media server to communicate with the storage server.
Note that all of the media servers in the configuration appear in the list, even
if the OpenStorage plug-in is not installed. Select a media server where the
OpenStorage plug-in is installed.
■
Enter the user name to log on to the storage host.
If the storage host does not require logon credentials, enter dummy
credentials.
Enter the password for the logon account.
■
Re-enter the password to confirm the password.
■
For a media server to communicate with and have access to a storage server,
it must be added to the Replication Director environment.
See “Adding the storage server credentials to a NetBackup server”
on page 25.
Storage Select the type of storage server to create:
server
■ For a NetApp 7-mode configuration, select NetApp OnCommand server
type
(7-mode) (Network_NTAP).
■ For a NetApp Clustered Data ONTAP configuration, select NetApp
OnCommand server (cluster-mode) (NTAP_CDOT).
■ For an EMC VNX and Celerra configuration, click in the Storage server
type field and then type EMC_Celerra.
Storage Enter the name of the storage server. The name that you use for the storage
server server must be used consistently throughout both the NetBackup environment
name
and the storage vendor environment.
Enter the exact name of the storage server, whether a fully-qualified name
or a short name.
■
■
■
In a NetApp 7-mode configuration, this is the OnCommand Unified
Manager.
In a NetApp Clustered Data ONTAP configuration, this is the computer
that hosts the NBUPlugin 2.0, not the OnCommand Unified Manager.
In an EMC configuration, this is the EMC Celerra server.
Click Next.

Creating a NetBackup storage server for snapshot replication
Updating an OpenStorage storage server to reflect plug-in updates
You've just configured a storage server, a disk pool, and a storage unit to contain
the primary snapshots. Configure additional disk pools (and storage units) for every
group of disk volumes that will contain snapshot replications of the primary
snapshots.
For example, in the following figure, two disk pools are necessary:
■
One disk pool that contains volumes to hold primary snapshots and act as a
source for other replications, and
■
A second disk pool that contains the volumes that are replication targets for
snapshot replications.

Updating an OpenStorage storage server to reflect
plug-in updates
If an OpenStorage partner updates their plug-in, update the NetBackup storage
server to reflect the new functionality of the plug-in.
For example, the NetApp plug-in used for Replication Director is the NBUPlugin.
If the OpenStorage plug-in is updated on the storage server, use the following
procedure to update the NetBackup storage server configuration to reflect this:

About disk pools for snapshots and snapshot
replication
An OpenStorage disk pool represents the disk storage that is exposed to NetBackup
through the OpenStorage API. A disk pool can represent one or more volumes.
Disk pools inherit their properties from the volumes that comprise the disk pools.
Snapshot and snapshot replication disk pools differ from other NetBackup disk pool
types as follows:
■
Only one storage unit can access a snapshot or a snapshot replication disk
pool.
■
Snapshot and snapshot replication disk pools observe no high or no low water
marks.
Configuring disk pools for snapshot and replication
About disk pools for snapshots and snapshot replication
One disk pool to be used for snapshots can be configured as part of the Storage
Server Configuration Wizard. At least one additional disk pool is necessary for
snapshot replication. The Disk Pool Configuration Wizard can also be launched
independently.
See “Creating disk pools for snapshot replication” on page 30.
The NetBackup administrator creates multiple disk pools to serve specific purposes
in a replication configuration. The volumes in a disk pool must have the properties
that match their intended purpose.
For example, the following disk pools are necessary to create a snapshot volume
and replicate it to target volumes:
■
A disk pool that contains a volume where the initial snapshot can be created.
The volume must have the Snapshot and Primary attributes set.
See “Primary + Replication source snapshot storage unit” on page 58.
■
A disk pool that contains a volume with the Snapshot and the Replication
target properties set to serve as the target for a replica snapshot.
See “Replication target snapshot storage unit” on page 59.
The following topic describes the roles that disk pools and storage units can serve
in a Replication Director configuration:
See “About configuring storage lifecycle policies for snapshots and snapshot
replication” on page 51.
About disk volumes for snapshots and snapshot replication
For snapshots and snapshot replication, all of the volumes in a disk pool must be
homogeneous; that is, they must have the same properties. The NetBackup Disk
Pool Configuration Wizard enforces compliance, as does the Change Disk Pool
dialog box.
The storage administrator defines the properties and the replication topology of the
disk volumes. The NetBackup administrator creates disk pools, based on the
properties of the volumes.
■
The volume properties define in what capacity the volumes can be used:
Snapshot
The default property. All volumes that are used for
snapshots or snapshot replication must have this property.
Primary
The volume can be used for snapshot creation.
Replication source
The volume can be used as a source for replicating
snapshots.
28
Configuring disk pools for snapshot and replication
About disk pools for snapshots and snapshot replication
Replication target
The volume can be used as a target for snapshot
replication.
Mirror
The volume is a mirror for snapshots. Mirror snapshots
have the same life span as the original snapshot.
■
The replication topology defines the source and the target volumes for replication.
For example, volume S1 replicates to T1, volume S2 replicates to T2, and so
on.
When you configure your NetBackup disk pools, add the source volumes (Sn)
to the disk pool you use for snapshot creation. Then, add the target volumes
(Tn) to the disk pool that is the target of the replication.
■
The Disk Pool Configuration Wizard may not display all of the properties,
depending on the underlying volumes.
For example, if a NetApp SnapMirror relationship is not defined at the volume
layer, then the Mirror property does not appear in the wizard panel for selection.
Table 4-1 shows the properties that are required for snapshots and snapshot
replication volumes, depending on their intended purpose in the NetBackup snapshot
and snapshot replication process.

Configuring disk pools for snapshot and replication
Creating disk pools for snapshot replication
Creating disk pools for snapshot replication
One disk pool can be configured as part of the Storage Server Configuration
Wizard to contain primary snapshots. Additional disk pools are necessary for
snapshot replication.
You can run the bpstsinfo command to view the replication properties of the
volumes and understand which volumes to include in the various disk pools.
See “Using bpstsinfo to view the replication topology of a device” on page 41.
To create a disk pool
1
Select Media and Device Management. In the right pane, click Configure
Disk Pool.
2
In the Disk Pool Configuration Wizard welcome panel, click Next.
3
Select the type of disk pool that you want to create.
4
On the Select Storage Server panel, select the storage server. Click Next.

5
The Select Volumes panel presents all of the volumes that have been
configured in the storage of the OpenStorage partner by the storage
administrator.
You've already created one disk pool as part of the Storage Server
Configuration Wizard to contain the primary snapshots that can serve as a
source for replication. Now create a disk pool that can serve as a replication
target.
To create a disk pool that is a target for replication, select Replication target.
NetBackup filters the volumes for selection so that dissimilar volumes are not
combined.
Note that in the Replication column, all the volumes have both Source and
Target properties. That means that the volume can serve as both a target for
replications as well as a source for another replication.
Expand the column to display other properties of the volume. For example,
whether the volume is configured to be a mirror.
Another method to filter the volumes is to first clear the Primary, Replication
source, and Replication target properties. Then, click on a specific volume.
The wizard panel filters the volumes, displaying only those volumes that match
the properties of the selected volume.
Note: For 7-mode, when the NBUPlugin is installed on the OnCommand Unified
Manager, a NetBackup group is automatically created on that server. You must
use the NetApp Management Console to add resource pools to the NetBackup
group so that the resource pools are exposed to NetBackup.
See the section called “Regarding disk pools for OnCommand Unified Manager
storage servers” on page 132.
6
Select the volume(s) to be part of this disk pool. Click Next.
7
In the Additional Disk Pool Information panel, name the disk pool.
See “NetBackup naming conventions” on page 16.
The available size that is listed is the total amount of space available in the
pool. The raw size is the total raw, unformatted size of the storage in the disk
pool. Click Next.

Configuring disk pools for snapshot and replication
Updating disk pools after volumes are added, are deleted, or are changed
10 After the disk pool creation completes, create a storage unit that uses the new
disk pool. A storage unit that uses this disk pool is necessary for snapshot
replication.
Select Create a storage unit that uses X where X is the disk pool and then
click Next.
11 In the Storage Unit Creation panel, name the storage unit.
Select the media server(s) that can use the storage unit.
Use any available media server to
transport data.
NetBackup selects any media server to
access the storage unit.
Use only the selected media servers.
NetBackup uses only the media server that
is specified to access the storage unit.
Only media servers that have the OpenStorage plug-in installed appear in this
list. For a media server to communicate with and have access to a storage
server, it must be added to the Replication Director environment.
Configure additional disk pools (and storage units) for every group of disk volumes
that will contain snapshot replications of the primary snapshots.
Updating disk pools after volumes are added, are
deleted, or are changed
The storage administrator may change the properties of the volumes in a way that
affects the topology of the volumes. If these volumes are used in a Replication
Director environment, the changes may affect the capabilities of the disk pool. For
example, a volume change may make a volume in the disk pool no longer usable
by NetBackup.
If volume properties change, you must update the disk pools to which those volumes
belong. Depending on the volume changes, you may also have to change storage
units, storage unit groups, and storage lifecycle policies.
Note: If an OpenStorage partner updates the plug-in on a disk-array, update the
NetBackup storage server and the disk pools to reflect the new functionality of the
plug-in.
See “Updating an OpenStorage storage server to reflect plug-in updates”
on page 24.
See “Updating an OpenStorage disk pool to reflect plug-in updates” on page 34.

Configuring disk pools for snapshot and replication
How to resolve snapshot disk volume changes
How to resolve snapshot disk volume changes
Veritas recommends that you take the following actions when volume properties
or topology change:
■
Discuss the changes with the storage administrator. You need to understand
the changes so you can change your disk pools (if required) so that NetBackup
can continue to use them.
■
If the changes were unplanned, request that the changes be reverted so that
NetBackup functions correctly again.
NetBackup can process changes to the following volume properties:
■
Primary
■
Replication Source
■
Replication Target
If these volume properties change, NetBackup can update the disk pool to match
the changes. NetBackup can continue to use the disk pool, although the disk pool
may no longer match the storage unit or storage lifecycle purpose.
When you open the Change Disk Pool dialog box, NetBackup loads the disk pool
properties from the catalog. NetBackup queries the storage server for changes
when you either click the Refresh in the Change Disk Pool dialog box or when
you configure a new disk pool for the storage server.

Configuring storage units
and storage unit groups for
snapshots and snapshot
replication
This chapter includes the following topics:
■
Creating storage units for a Replication Director configuration
■
Creating storage unit groups for snapshots
Creating storage units for a Replication Director
configuration
A storage unit is a label that NetBackup associates with physical storage. For
snapshots and snapshot replication, a storage unit is configured to contain one
snapshot disk pool.
Storage unit creation is part of several other wizards. However, a storage unit can
be created directly from the Storage utility in the NetBackup Administration
Console.
To create a storage unit for snapshots or snapshot replication
1
In the NetBackup Administration Console, select the Storage utility.
2
Select Actions > New > New Storage Unit.
Configuring storage units and storage unit groups for snapshots and snapshot replication
Creating storage units for a Replication Director configuration
3
Enter a Storage unit name.
See “NetBackup naming conventions” on page 16.
4
Select the Storage unit type. For snapshots and snapshot replication, select
Disk.
5
Select a Disk type.
The Disk type identifies the type of storage unit. To configure snapshots and
snapshot replication, select OpenStorage (Vendor name).
6
7
A storage unit can contain either snapshot images or non-snapshot backup
images, but it cannot contain both. In the Storage unit configured for
drop-down list, indicate what the storage unit is to contain:
■
Backup storage unit
Upon selection, only those disk pools that can contain non-snapshot backups
are displayed in the dialog box.
■
Snapshot storage unit
To configure snapshots and snapshot replication, select Snapshot.
Upon selection, only those disk pools that can contain snapshots are
displayed in the dialog box. Once a storage unit contains snapshots, it
cannot contain non-snapshot backups.
Specify the properties that are required for the storage unit. Selecting a property
filters the disk pools and displays only those that have the property selected.
For example, select Replication source and Replication target to display
the disk pools that are configured to be both replication sources and targets
for other replications. If no properties are selected, all disk pools appear.
(If you already know the name of the disk pool that has the properties that you
want, select the disk pool from the Select disk pool drop-down menu. In that
case, no filtering is necessary.)
8
In the Select disk pool drop-down list, select the disk pool that this storage
unit is to contain. A storage unit can contain only one disk pool.
Click View Properties to display the properties of the selected disk pool.
47

9
Select the media server(s) that can use the storage unit.
Use any available media server to
transport data
NetBackup selects any media server to
access the storage unit.
Use only the following media servers
NetBackup uses only the media server(s)
that are specified to access the storage
unit.
Only the media servers that have the OpenStorage plug-in installed appear in
this list. For a media server to communicate with and have access to a storage
server, it must be added to the Replication Director environment.
See “Adding the storage server credentials to a NetBackup server” on page 25.
Note: A storage unit can represent many physical devices. When a storage
unit is a replication target, NetBackup lets the plug-in select which device to
use within the storage unit. For replication jobs, storage units and storage unit
groups ignore the Maximum concurrent jobs setting. NetBackup does not
attempt to throttle the parameters.
10 Click OK to save the storage unit configuration.
Creating storage unit groups for snapshots
Creating storage unit groups is optional. A snapshot storage unit group must be
comprised of storage units that have matching properties.
The following procedure describes how to create a storage unit group that consists
of the storage units that can contain snapshots.
To create a snapshot storage unit group
1
In the NetBackup Administration Console, expand NetBackup Management
> Storage.
2
Right-click Storage Unit Groups and select New Storage Unit Group.
3
Enter a storage unit group name for the new storage unit group. The storage
unit group name is case-sensitive.
See “NetBackup naming conventions” on page 16.
4
For the storage unit group to contain snapshots, select Snapshot in the
drop-down menu.
48
Configuring storage units and storage unit groups for snapshots and snapshot replication
Creating storage unit groups for snapshots
5
A storage unit group can contain only those storage units that share similar
properties. NetBackup filters the storage units for selection so that dissimilar
storage units are not combined in one storage unit group.
Note: The properties of the underlying storage units are read-only. You cannot
change the storage unit properties from this dialog box.
Select one or more properties to filter the storage units in the list. Only those
storage units that have the selected properties are displayed. For example,
select Replication source and Replication target to display only those storage
units that are configured to act as both replication sources and replication
targets.
Filter the storage units on the following properties:
6
■
Primary
Enable Primary to display the storage units that can contain the initial
snapshot of primary data.
■
Replication source
Enable Replication source to display the storage units that can serve as
a source for a replicated snapshot.
■
Replication target
Enable Replication target to display the storage units that can receive
replicated snapshots from a replication source.
■
Mirror
Optionally, enable Mirror to display the storage units that can serve as
a mirrored replication target. (For example, NetApp SnapMirror.)
■
Independent
Optionally, enable Independent to display the storage units that can
act as either a Mirror replication target (SnapMirror) or a non-mirror
replication target (SnapVault).
Add or remove storage units from the group:
■
To add storage units to the group, select the storage units from the
Available storage units list and click Add.
■
To remove storage units from the group, select the storage units from the
Storage units to be used in the group list and click Remove.

About configuring storage lifecycle policies for
snapshots and snapshot replication
A storage lifecycle policy (SLP) contains instructions in the form of storage
operations, to be applied to the data. Operations are added to the SLP that determine
how the data is stored and copied or replicated. For example, the NetBackup
administrator creates an operation that determines where the data exists as a
snapshot, as a replication, or as a duplication. The administrator also determines
the retention of the data at each storage unit or storage unit group.
Storage operations that are defined in the SLP use storage units that represent
disk pools. An SLP that is configured for snapshots or snapshot replication must
contain a specific, hierarchical combination of operations.
Configuring storage lifecycle policies for snapshots and snapshot replication
About configuring storage lifecycle policies for snapshots and snapshot replication
The following figure represents an SLP for a replication scenario. In the example,
the following operations are used:
■
A Snapshot operation creates a snapshot.
■
A Replication operation replicates the snapshot to another volume.
■
A Backup From Snapshot operation creates a tar-formatted backup from the
snapshot.
■
A Duplication operation copies the backup to tape.
Table 6-1 describes the four types of operations that are required in this example
replication scenario.

Duplication
The operation must be a Replication operation and it must be the replication
partner to the source storage unit.
The retention type determines what replication method is used. For example, if
retention type Fixed or Expire after copy is selected for a NetApp storage
system, the SnapVault replication method is used.
The storage must be a snapshot storage unit that has the Replication target
property set. Since no other replica is created from this operation in this example,
it does not need to have the Replication source property set.
The operation must be a Backup From Snapshot operation. This operation
creates a backup image from the snapshot.
The storage must be a backup storage unit.
Operation 4 makes a duplicate copy from the tar-formatted backup copy. In this
example, the copy is duplicated to tape media.
■
■
The operation must be a Duplication operation. This operation creates a backup
copy of the tar-formatted image.
The storage must be a backup storage unit.
After the SLP is configured for different operations, the NetBackup administrator
configures a backup policy that points to the snapshot SLP.
The SLP Parameters host properties in the NetBackup Administration Console
allow administrators to customize how SLPs are maintained and how SLP jobs run.
Best-practice information about SLPs appears in the following document:
http://www.veritas.com/docs/TECH208536
Creating a storage lifecycle policy for snapshots
and snapshot replication
Use the following procedure to configure a storage lifecycle policy that creates
snapshots and snapshot replications with Replication Director. Only those options
that are necessary to configure an SLP for Replication Director are listed.
53
Configuring storage lifecycle policies for snapshots and snapshot replication
Creating a storage lifecycle policy for snapshots and snapshot replication
To configure a storage lifecycle policy to create snapshots and snapshot
replication
1
In the NetBackup Administration Console, expand NetBackup Management,
and then expand Storage. Select Storage Lifecycle Policies.
2
Click Actions > New > Storage Lifecycle Policy.
3
In the New Storage Lifecycle Policy dialog box, enter a Storage lifecycle
policy name.
See “NetBackup naming conventions” on page 16.
4
Click Add to add operations to the SLP. The operations are the instructions
for the SLP to follow and apply to the data that is specified in the backup policy.
5
In the Properties tab of the New Storage Operation dialog box, select
Snapshot from the Operation drop-down menu.
This Snapshot operation creates a snapshot of the primary data and serves
as the source for other operations in the SLP. For example:
■
A Replication operation.
See “Replication operation in an SLP” on page 60.
54

■
An Index From Snapshot operation.
See “Index From Snapshot operation in an SLP” on page 62.
6
In the Storage unit drop-down menu, select a storage unit. NetBackup displays
only those storage units that are configured to contain primary snapshots.
7
Select the Retention type and the Retention period for the data in this storage
unit. The Retention period option does not appear for all Retention type
selections. Click OK.
8
To replicate the primary snapshot, create a Replication operation that is based
on the Snapshot operation. Click on the Snapshot operation and then select
Add. The New Storage Operation dialog box appears.
9
In the Operation drop-down menu, select Replication.
10 Under Storage, select a Storage unit that is configured to contain replicated
snapshots. NetBackup displays only those storage units that can act as target
destinations.
11 Select the Retention type and the Retention period for the data in this storage
unit.
A Mirror retention indicates that the NetApp volume SnapMirror method is to
be used for the replication method. If a non-mirror retention type is selected,
the NetApp SnapVault replication method is used.
Optionally, indicate an Alternate read server that is allowed to read a snapshot
that was originally written by a different media server. Click OK.
12 The Window tab displays for the following operation types: Backup From
Snapshot, Duplication, Import, Index From Snapshot, and Replication.
Create a window during which secondary operations can run.
13 Click OK to create the storage operation.
Continue to create operations, depending on the needs of your environment.
To cascade storage operations in the SLP, make sure to select the correct parent
operation as the source for the child operation. If the correct operation is not
selected, you unintentionally perform an operation on an incorrect source.
Operation types in a storage lifecycle policy
The Operation selections are the instructions in the storage lifecycle policy. The
following topics describe the purpose of each operation.

■
See “Replication operation in an SLP” on page 60.
■
See “Index From Snapshot operation in an SLP” on page 62.
■
Backup operation. When a Backup operation appears in an SLP, it must be
the first operation. In an SLP that is configured for Replication Director, the first
operation must be a Snapshot operation. Since this guide concentrates on
Replication Director, the Backup operation is not described here.
■
See “Backup From Snapshot operation in an SLP” on page 69.
■
See “Duplication operation in an SLP” on page 70.
■
Import operation. An Import operation is used in Auto Image Replication, in
which an SLP is used to import a backup into a target NetBackup domain. Auto
Image Replication does not apply to Replication Director in this release so the
Import operation is not described here.
All operations are described in the NetBackup Administrator's Guide, Volume I
or the online Help in the NetBackup Administration Console.
Snapshot operation in an SLP
A Snapshot operation creates a point-in-time, read-only, disk-based copy of data.
NetBackup provides several types of snapshots, depending on the device where
the snapshot occurs.
Use a Snapshot operation as the first operation in a storage lifecycle policy for a
NetBackup Replication Director configuration.

The following topics describe the types of snapshot storage units that
can be used as the storage for a snapshot operation:
■
See “Primary snapshot storage unit” on page 58.
■
See “Primary + Replication source snapshot storage unit” on page 58.
■
See “Replication source + Replication target snapshot storage unit”
on page 59.

■
■
■
See “Replication source + Replication target + Mirror snapshot storage
unit” on page 60.
See “Replication source + Replication target + Mirror snapshot storage
unit” on page 60.
A Storage unit selection is necessary in the following situations:
■
■
If the Snapshot is to be used by a subsequent Replication operation.
The storage unit that is specified for the Snapshot operation must
be a snapshot-capable storage unit that represents the primary
storage.
If the SLP contains only one operation and that is a Snapshot
operation, specify a storage unit. NetBackup uses that storage unit
to determine which media server to use to launch the snapshot job.
If neither situation applies to the SLP, the administrator may select No
storage unit or may simply make no selection. NetBackup uses the
storage unit that is selected for the Backup From Snapshot operation.
Child of
A Snapshot operation cannot serve as the child of any other operation.
Therefore, do not click on any other operation in the SLP when adding
a Snapshot operation.
See “Creating a storage lifecycle policy for snapshots and snapshot
replication” on page 53.
Source for
A Snapshot operation can be the source for the following operations:
■
Backup From Snapshot
■
Index From Snapshot
■
Replication operation
Hierarchy notes
If a Snapshot operation appears in an SLP, it must be first in the
operations list.
Job type
A Snapshot operation generates a Snapshot job in the Activity Monitor.
Window
Snapshot operations do not offer the option to create an SLP window.

Primary snapshot storage unit
A snapshot operation can use a Primary snapshot storage unit. That is, the storage
unit represents a disk pool that contains the volumes that have only the Primary
property set.
Figure 6-2 shows an SLP that contains one primary-only Snapshot operation, one
Backup From Snapshot operation, and one Duplication operation. The Backup
From Snapshot operation is used to create a backup from the snapshot on the
primary-only Snapshot operation. After the backup is created, it is duplicated to a
Duplication operation.

and Mirror.
An operation with these properties can serve as both:
■
A Replication source in a cascading configuration.
■
A mirrored Replication target in a cascading configuration. A mirrored
Replication target must have a forced Mirror retention type.
Replication target + Mirror snapshot storage unit
An SLP can use a snapshot storage unit that represented a disk pool that contains
volumes that have the following properties: Replication target and Mirror.
A mirrored Replication target must have a forced Mirror retention type.
Replication operation in an SLP
Use the Replication operation for the following types of replication:
■
NetBackup Replication Director to replicate a snapshot, as shown in Figure 6-6.

Index From Snapshot operation in an SLP
The Index From Snapshot operation indexes the contents of existing snapshots.
When NetBackup indexes a snapshot, it creates an image catalog file in the
NetBackup catalog for each snapshot. The presence of an image catalog file assists
the user when a file needs to be restored from the snapshot, as described in
Table 6-4.
The Backup From Snapshot operation also creates an image catalog file. An
Index from Snapshot may not be required if a Backup From Snapshot occurs
frequently enough for the restore needs in your environment. For example, if the
Backup From Snapshot runs once per week but file restores are required daily,
consider using the Index from Snapshot.
The actual restore of the snapshot requires that the snapshot be mounted, regardless
of whether an Index from Snapshot has been performed or not.

Index From Snapshot operation characteristics
Characteristic Description
Storage unit
selection
The Index From Snapshot operation does not write data to a storage unit. However, a storage
unit selection is needed to select the media server that to be used to access the snapshot. As a
best practice, use the storage unit from the Snapshot or Replication operation that is the source
for this operation.
Child of
When an Index From Snapshot operation appears in an SLP, it must be the child of a Snapshot
or Replication operation.
Therefore, click on either a Snapshot or a Replication operation in the SLP when adding an Index
From Snapshot operation.
See “Creating a storage lifecycle policy for snapshots and snapshot replication” on page 53.
Source for
While an Index From Snapshot operation cannot be the source for any operation, a Replication
operation can follow it.
63
Configuring storage lifecycle policies for snapshots and snapshot replication
Operation types in a storage lifecycle policy
Table 6-5
Index From Snapshot operation characteristics (continued)
Characteristic Description
Hierarchy notes
The Index From Snapshot operation can consume system resources and requires that each
snapshot be mounted to create the image catalog file.
See “Determining where and when the Index From Snapshot operation occurs” on page 64.
Job type
An Index From Snapshot operation generates an Index From Snapshot job in the Activity
Monitor.
Window
An SLP window can be created for an Index From Snapshot operation.
Consider the following items before using the Index From Snapshot operation:
■
The Index From Snapshot operation is supported only in a Replication Director
configuration.
■
Standard, MS-Windows, NDMP, and VMware backup policy types support the
use of storage lifecycle policies that contain the Index From Snapshot operation.
Note: However, a Standard or MS-Windows policy with NDMP Data Mover
enabled is not supported.
■
The Index From Snapshot operation can run from a full or an incremental
schedule. The file entries that are added to the image catalog file for either
schedule are the full set of files since all files can be restored from that snapshot.
To do so allows for the most efficient restore, however, more space is consumed
in the NetBackup catalog by the image catalog file.
Determining where and when the Index From Snapshot
operation occurs
Including the Index From Snapshot operation requires some consideration as the
operation can consume system resources and require additional time to perform.
For example, to perform the operation can require that a snapshot be mounted or
that NetBackup gather content details from the file system to populate the catalog.
To help mitigate the extra resource and time that the operation may take, the system
administrator can control when and where the Index From Snapshot operation
runs:
■
Use the storage lifecycle policy Window tab to schedule when the Index From
Snapshot operation can run. Schedule the operation to run when it is least likely
to interfere with other jobs.
64
Configuring storage lifecycle policies for snapshots and snapshot replication
Operation types in a storage lifecycle policy
■
Use the following points to determine where to position the Index From
Snapshot operation in the SLP operations list:
■
Each NetBackup environment needs to determine where the operation works
best in a specific SLP. To place the Index From Snapshot operation too
early (toward the top of the operations list), may consume time when the
restore capabilities are not needed. To place the operation toward the end
of the operations list may cause the administrator to delay a restore until
earlier snapshots or replications complete.
■
Use the Index From Snapshot operation in an SLP only once. A restore
can be performed from any snapshot after one image .f file is created.
■
Any operations list that includes a Backup From Snapshot operation does
not need an Index From Snapshot operation. The Backup From Snapshot
operation creates an image .f file. The only exception is if the index is
needed for restores before the Backup From Snapshot operation occurs.
■
An Index From Snapshot operation cannot have any dependents. An SLP
cannot validate an Index From Snapshot operation with children. Figure 6-8
shows an SLP with a valid configuration.
Figure 6-9 is also a valid configuration. A Replication operation follows the
Index From Snapshot operation, but it is not indented. The Replication
operation is a child of the Snapshot operation, not a child of the Index From
Snapshot operation.
To add a Replication operation after an Index From Snapshot operation,
click on the Snapshot operation, and then click Add.

Pre-requisites for indexing for an NDMP policy
The following are pre-requisites to enable indexing for an NDMP policy:
■
You must add a disk array host to NetBackup.
■
Make sure that the Storage Virtual Machine (SVM) login account with the ontapi
application is in the unlocked state.
Indexing jobs fail with error code 2113 if the account is in the locked state.
Note: Indexing NDMP policies is supported only for NetApp Clustered Data ONTAP
configurations.
Indexing jobs fail with error code 2113 if the account is in the locked state.
Run the following command to check the account details and verify the status of
the account, the Locked column shows ‘yes’ if the account is locked:
PUNBNRRDF _2240_01::> security login show -vserver Primary_VS_Auto_1
-user-or-group-name demo
The following is the output if the account is locked:
Run the following command on the cluster to unlock the account:
PUNBNRRDF_2240_01::> security login unlock -vserver Primary_VS_Auto_1
-username demo
Run the login command again to check the status, the ‘Locked’ column would show
‘no’ as shown in the output:
66
Configuring storage lifecycle policies for snapshots and snapshot replication
Operation types in a storage lifecycle policy
After you unlock the account, you can proceed with the steps to configure indexing
with an NDMP policy.
Note: The commands can change with the ONTAP version change. Please check
your NetApp documentation for information about the latest commands.
Configuring indexing for an NDMP policy
For NDMP indexing, you must add a disk array host to NetBackup. The disk array
host is the Storage Virtual Machine (SVM) that holds the snapshot or replica from
which, the index would be generated. To connect to the SVM, you must use a logical
interface (LIF) connection which has management access enabled.
Note: Indexing NDMP policies is supported only for NetApp Clustered Data ONTAP
configurations.
See “About creating backup policies for Clustered Data ONTAP with Replication
Director” on page 141.
To configure indexing for an NDMP policy
1
On the NetBackup server NetBackup Administration Console, expand Media
and Device Management > Credentials > Disk Array Hosts.
2
Under the Actions menu, select New > New Disk Array Host.
3
In the Media and Device Management – NetBackup dialog box, enter the name
of the SVM that holds the snapshot or the replica copy that is to be used for
indexing.
To connect to the SVM, you must use a logical interface (LIF) connection which
has management access enabled.
67

4
Click OK.
The New Disk Array Host dialog box is displayed.
5
Select NetApp from the Disk Array Host Type drop-down list.
6
Enter the user name and password details and click OK.
The disk array credentials are the admin credentials of the NetApp SVM.
Note: The credentials that you provide for the SVM are not validated when
you add the disk array host. Incorrect credentials can cause NDMP indexing
job failure with error code 2113. Make sure that you provide the right disk array
host credentials.

Table 6-6
Characteristic Description
Hierarchy notes
An SLP may contain more than one Backup From Snapshot operation.
If the first Backup From Snapshot operation fails with an unrecoverable
error, NetBackup does not attempt the second one.
Note: The SLP may contain only one Backup From Snapshot operation
if the SLP is used by an NDMP policy (or a Standard or MS-Windows
policy with NDMP Data Mover enabled).
Job type
A Backup From Snapshot operation generates a Backup job in the
Activity Monitor.
The Backup job that results from the Backup From Snapshot operation
is under the control of the SLP Manager. If an SLP window is configured,
the Backup job runs during the configured SLP window. If no SLP window
is configured, the Backup job can run at any time; possibly outside of the
backup window as configured in the backup policy. Users may experience
a slight degradation in performance on the client or the client storage
device while NetBackup accesses the snapshot.
Window
An SLP window can be created for a Backup From Snapshot operation.

Note: Retention is not associated with the Index From Snapshot operation because

Expire after copy retention type for SLP operations
The Expire after copy retention indicates that after all direct (child) copies of an
image are successfully duplicated to other storage, the data on this storage is
expired. The last operation in the SLP cannot use the Expire after copy retention
type because no subsequent copy is configured. Therefore, an operation with this
retention type must have a child.
Veritas recommends that you not enable Expire after copy retention for any storage
units that are to be used with SLPs with either of the following: Accelerator or
synthetic backups. The Expire after copy retention can cause images to expire
while the backup runs. To synthesize a new full backup, the SLP backup needs the
previous backup image. If the previous image expires during the backup, the backup
fails.
73
Configuring storage lifecycle policies for snapshots and snapshot replication
Retention types for storage lifecycle policy operations
Note: Although synthetic backups do support the use of storage lifecycle policies,
SLPs cannot be used for the multiple copy synthetic backups method.
If a policy is configured to use an SLP for the backup, the retention that is indicated
in the SLP is the value that is used. The Retention attribute in the schedule is not
used.
An image copy with an Expire after copy retention is expired as soon as all of its
direct child copies have been successfully created. Any mirrored children must also
be eligible for expiration.
Fixed retention type for SLP operations
The Fixed retention indicates that the data on the storage is retained for the specified
length of time, after which the backups or snapshots are expired.
An image copy with a Fixed retention is eligible for expiration when all of the
following criteria are met:
■
The Fixed retention period for the copy has expired.
■
All child copies have been created.
■
All child copies that are mirror copies are eligible for expiration.
The Fixed retention period is always marked from the original backup time of the
image. For example, if a tape device is down, causing a 2-day delay in creating a
duplicate tape copy, the expiration time of the duplicate copy is not different due to
the 2-day delay. The expiration time of the duplicate copy is still x days from the
time that the original backup was completed. It does not matter when the copy was
created.
Maximum snapshot limit retention type for SLP operations
The Maximum snapshot limit determines the maximum number of snapshots that
can be stored for a particular policy and client pair.
When the maximum is reached, the next snapshot causes the oldest job-complete
snapshot to be deleted. A snapshot job is considered to be complete once all of its
configured dependent copies are complete. (Dependent copies are created as a
result of Backup From Snapshot, Index From Snapshot, or Replication
operations.) The practice is referred to as rotation. This retention type applies only
to snapshots, and not to backups.
For example, Policy P1 contains two clients: C1 and C2. After the policy runs four
times, it creates four snapshot images for C1 and four images for C2. If the
Maximum snapshot limit is set to four, when the policy runs for the fifth time,
74
Configuring storage lifecycle policies for snapshots and snapshot replication
Retention types for storage lifecycle policy operations
NetBackup deletes the first snapshot that was created for both C1 and C2 to
accommodate the fifth snapshot.
The Maximum Snapshots parameter in the Replication Director Options dialog
box determines the maximum number of snapshots. To access the dialog box, click
Options in the backup policy.
Figure 6-14
Replication Director Options dialog box
Mirror retention type for SLP operations
A mirror replica of a snapshot is eligible for expiration as soon as:
■
All immediate child copies are successfully created.
■
All immediate child copies that are mirrors are eligible for expiration.
75
Configuring storage lifecycle policies for snapshots and snapshot replication
Retention types for storage lifecycle policy operations
The selection of the Mirror retention indicates that NetApp volume SnapMirror is
to be used as the replication method. If any non-mirror retention type such as Fixed
or Expire after copy is selected for the Replication operation, the NetApp
SnapVault replication method is used.
In mirror replication, the replica copy is dependent on the existence of the source.
(The source can be the original snapshot or another replica.) Therefore, the retention
of the replica depends on the retention of the source. If the source is deleted, the
mirror is automatically deleted.
In non-mirror replication, the replica is independent of the source and can have an
independent retention. If the source is deleted, the non-mirror replica is not affected
and can be used longer than the source. Or, if the replica is deleted first, it is not
recreated and the source can be kept longer than the replica.
Target retention type for SLP operations
This setting is used in Auto Image Replication in an Import storage lifecycle policy.
Every Import SLP must have at least one operation with a Target retention.
The Target retention is enforced at the target domain, but the actual retention for
the data is specified by the administrator at the source domain.
Target retention indicates that the data at the target master shall use the expiration
date that was imported with the image. The date is fixed because the copy must
have a fixed retention.
Similar to the Fixed retention, an image copy with a Target retention retention is
eligible for expiration when all of the following criteria are met:
■
The Fixed retention period for the copy has expired.
■
All child copies have been created.
■
All child copies that are mirror copies are eligible for expiration.

on the NAS host and avoid mounting each client.
Figure 7-1 shows a disk array that many clients access to store data. Only the array
name is listed in the Clients tab of the NetBackup policy, not individual production
clients. The volume on the array that the clients use is listed in the Backup
Selections tab of the policy.

Differential: The OpenStorage partner creates a snapshot that
is completely dependent on the source. This parameter is based
on copy-on-write technology. The device creates a cache object
to maintain the original blocks of the snapshot when the blocks
are modified.
Plex: The OpenStorage Partner creates a snapshot that is
completely independent of the source snapshot. This option is
based on mirror-break-off technology. When a mirror device is
attached to the source, the contents of the mirror device is exactly
the same as the source device. When the relationship is broken
between the two, the mirror device is separated from the source.
The mirror device acts as a point-in-time copy.
Clone: The OpenStorage Partner creates an independent copy
of the volume. The copy process can take some time as the entire
copy must be complete. The snapshot that is created is
independent of the source.
Maximum Sets the maximum number of snapshots to be retained at one time.

86
Configuring backup policies for snapshots and snapshot replication
Configuring a Standard or MS-Windows policy to protect NAS volumes or SAN-connected devices
Do not specify more than 64 backup selections in a VSS policy. If more than
64 backup selections are specified, the snapshot jobs fail with status code 156.
This is due to a documented limitation of the VSS infrastructure. To
accommodate more than 64 backup selections, divide the backup selections
between multiple policies.
Note: Backup selections for both SAN devices and NAS volumes are not
supported in a single backup policy.
To protect NAS data, specify the backup selection from the client perspective.
For example, suppose that the client data resides in a volume (/vol/vol1) on
a filer (NAS1):
■
UNIX example: The data is NFS-mounted to /mnt2/home on the UNIX client.
Specify /mnt2/home in the Backup Selections list.
■
Windows example: The data is shared by means of CIFS as vol1 on the
Windows client.
Specify \\nas1\vol1 in the Backup Selections list.
For a Clustered Data ONTAP policy, the backup selection refers to a volume
on a Storage Virtual Machine (or Vserver).
■
Windows path names must use the Universal Naming Convention (UNC),
in the form \\server_name\share_name.
■
For NFS mounts, the data must be manually mounted by means of the
mount command (or by using /etc/fstab), but not auto-mounted.
■
(NetApp 7-mode only) Use the nosharecache option to mount qtrees that
are under the same volume. For example:
mount -o vers=3,nosharecache filer:/vol/volume1/qtree1 /mnt1
87
Configuring backup policies for snapshots and snapshot replication
About NDMP support for Replication Director
■
(NetApp 7-mode only) To back up a qtree, mount the qtree only. Do not
mount the volume. That is, do not include the volume in the backup selection
path.
If the volume is mounted and a qtree from the same is used as a backup
selection, the NetApp Plug-in for Veritas NetBackup (NBUPlugin) considers
it to be a volume only and performs only volume-specific operations.
For example, to back up a qtree, enter: \\filer\q1
The following entry is incorrect and creates a snapshot of the entire volume:
\\filer\volume1\q1

For the NetBackup Client Service to write to the CIFS volume, it must have
permission to do so. When a backup policy is saved, a message displays
stating that this permission is necessary. By default, NetBackup is installed as
a local system account and may not have the necessary CIFS permissions.
Change the logon property of the NetBackup Client Service to an account with
access to the CIFS share.
If the logon property is not changed for the NetBackup Client Service, the policy
validation fails with status code 4206.
See “Configuring the NetBackup Client Service” on page 15.

About NDMP support for Replication Director
Replication Director can use NDMP to back up, browse, and restore from snapshots.
How you configure the backup policy determines whether NetBackup uses NDMP
to create snapshots of the NAS host or volume.
When deciding whether to use NDMP consider the following aspects:

Limitations of Replication Director with NDMP
Consider the following limitation before configuring NDMP to be used with Replication
Director:
■
The Solaris_x86 operating system is not supported.
■
The Multiple copies NetBackup policy option is not supported for image copies
in the NDMP data format.
89
Configuring backup policies for snapshots and snapshot replication
About NDMP support for Replication Director
■
The Restore the file using a temporary filename restore option is not
supported on Windows clients.
■
Restores to a local file system are not supported with an MS-Windows or a
Standard policy that has the NDMP Data Mover enabled.
■
Do not include both the qtree and the volume on which the qtree resides in the
same Backup Selection list.
■
Only one NDMP backup of a snapshot per backupid is allowed.
■
The Index From Snapshot operation is supported only in a Replication Director
configuration, however, a Standard or MS-Windows policy with NDMP Data
Mover enabled is not supported.
Note: The Index From Snapshot operation is not supported for NetApp ONTAP
7-mode.
See “Index From Snapshot operation in an SLP” on page 62.
■
When you make changes to the NDMP policy after the last full or incremental
schedule (for example, if you add or delete a backup selection), the content for
the next incremental retrieves the entire content of the snapshot rather than
retrieving only the content that has changed. The next incremental schedule
however, after only retrieves content that has changed as expected.
Authorizing NetBackup access to a NAS (NDMP) host
Before NetBackup can perform backups using NDMP, it must have access to the
NAS (or NDMP) host.
Note: Perform the following procedure on the master server (not media server) if
you plan to create snapshots using Replication Director.
To authorize NetBackup access to the NDMP host
1
On the NetBackup server NetBackup Administration Console, expand Media
and Device Management > Credentials > NDMP Hosts.
2
Under the Actions menu, select New > New NDMP Host.
90

About NDMP support for Replication Director
3
In the Add NDMP Host dialog box, enter the name of the NDMP server for
NetBackup to back up.
If you are using NetApp's Clustered Data ONTAP, the NDMP host must be a
Storage Virtual Machine (SVM).
The NDMP host name is case-sensitive. The name must match the name that
is entered here whenever this host name is used.
Note: If you do not plan to use Replication Director and you add NDMP host
credentials using the fully qualified domain name (FQDN), you must also
indicate the fully qualified domain name on the client for lookups. That is, the
server list in the Backup, Archive, and Restore client interface must list the
NDMP host by the FQDN as well.
If you add NDMP host credentials using a short name, you can use either the
short name or the FQDN in the client server list.

ALL_FILESYSTEMS and VOLUME_EXCLUDE_LIST directives
The ALL_FILESYSTEMS directive provides a method to include all file systems and
volumes on an NDMP filer in an NDMP backup policy.
You can exclude specific volumes from an ALL_FILESYSTEMS backup selection if
you do not want to back up every volume on an NDMP filer. Use the
92
Configuring backup policies for snapshots and snapshot replication
About NDMP support for Replication Director
VOLUME_EXCLUDE_LIST directive for this purpose. You may use valid wildcard
characters in the VOLUME_EXCLUDE_LIST statement.
Note: The following examples use selections that are specific to NetApp Data
ONTAP 7-mode. For specific examples of backup selections for other configurations,
refer to the appropriate documentation.
The VOLUME_EXCLUDE_LIST statements must precede ALL_FILESYSTEMS statement.
For example:
VOLUME_EXCLUDE_LIST=/vol/Hr_allfiles_vol01
ALL_FILESYSTEMS
or
VOLUME_EXCLUDE_LIST=/vol/testvol*
ALL_FILESYSTEMS
To specify multiple values in a VOLUME_EXCLUDE_LIST statement, separate the
values with a comma. For example:
VOLUME_EXCLUDE_LIST=/vol/Hr_allfiles_vol01,/vol/testvol*
ALL_FILESYSTEMS
You can also specify more than one VOLUME_EXCLUDE_LIST statement with an
ALL_FILESYSTEMS directive. For example:
VOLUME_EXCLUDE_LIST=/vol/Hr_allfiles_vol01
VOLUME_EXCLUDE_LIST=/vol/testvol*
ALL_FILESYSTEMS
A VOLUME_EXCLUDE_LIST statement may include a maximum of 256 characters.
Create multiple VOLUME_EXCLUDE_LIST statements if necessary to avoid exceeding
the limit of 256 characters. If you specify more than 256 characters, the volume list
is truncated. A truncated statement may result in a backup job failure, and the error
message Invalid command parameter(20) is displayed.
If the backup selection includes read-only volumes or full volumes, an NDMP backup
job fails with the status code 20 (Invalid command parameter(20)). If you
encounter a similar NDMP backup job error, review the ostfi logs to identify the
volumes for which the failure occurred. You can use VOLUME_EXCLUDE_LIST
statements with the ALL_FILESYSTEMS statement to exclude the read-only volumes
and the volumes with insufficient space.
93
Configuring backup policies for snapshots and snapshot replication
About NDMP support for Replication Director
In a NetBackup Replication Director environment where snapshots are replicated
to a secondary filer, Veritas recommends that you use storage lifecycle policies to
control backups on the secondary filer.
On NetApp 7-mode storage systems, it is generally not recommended for users to
store files in /vol/vol0 because the volume contains filer system files. For this
reason, vol0 should be excluded from the backup if the ALL_FILESYSTEMS directive
is used in the backup policy. The following is a backup selection list that excludes
/vol/vol0:
VOLUME_EXCLUDE_LIST=/vol/vol0
ALL_FILESYSTEMS
■
Do not use ALL_FILESYSTEMS to backup all volumes on a secondary filer.
Inconsistencies may occur when automatically created NetApp FlexClone
volumes are backed up or restored. Such volumes are temporary and used as
virtual copies or pointers to actual volumes and as such do not need to be backed
up.
■
If you must back up all volumes on a secondary filer, Veritas recommends that
you exclude the FlexClone volumes as well as replicated volumes. For example:
VOLUME_EXCLUDE_LIST=/vol/Clone_*
VOLUME_EXCLUDE_LIST=/vol/*_[0-9]
VOLUME_EXCLUDE_LIST=/vol/*_[0-9][0-9]
VOLUME_EXCLUDE_LIST=/vol/*_[0-9][0-9][0-9]
ALL_FILESYSTEMS
This example assumes all FlexClone volumes and only FlexClone volumes
begin with /vol/Clone_. Adjust the volume specifications appropriately for your
environment.
■
VOLUME_EXCLUDE_LIST applies only to ALL_FILESYSTEMS. It does not apply to
explicit backup selections or wildcard-based backup selections.
If you use the ALL_FILESYSTEMS directive in an NDMP policy for Clustered Data
ONTAP, you must exclude each selected SVM's root volume using the
VOLUME_EXCLUDE_LIST directive. Otherwise the backups fail.
For more information, refer to the following topic:
See “About creating backup policies for Clustered Data ONTAP with Replication
Director” on page 141.
Backups from snapshots for NDMP policies fail when the import of a snapshot fails
for volumes where logical unit numbers (LUNs) reside with status code 4213
(Snapshot import failed). To avoid this error, use the VOLUME_EXCLUDE_LIST
directive to exclude any volumes that are used to create LUNs accessed through
a storage area network (SAN).
94
Configuring backup policies for snapshots and snapshot replication
About NDMP support for Replication Director
Configuring an NDMP policy in a multi-network environment
In an environment where NetApp storage systems are connected to multiple
networks, the NDMP policy for Replication Director can be configured to use a
specific network for the NDMP backup traffic. To do this, use the Backup From
Snapshot operation in the storage lifecycle policy.
If the backup is from the primary storage system (that is, a Snapshot operation
plus a Backup From Snapshot operation in one SLP), then the host name
associated with the network to use should be entered in the Clients tab of the
policy.
Note: The following examples use commands that are specific to NetApp Data
ONTAP 7-mode. Commands can change from version to version. For the latest
vendor-specific commands, refer to the vendor's documentation.
For cases where the snapshot is replicated, the default primary name of the
secondary storage system is used. To use a different network, set the
ndmpd.preferred_interface options on the storage system to the interface that
is connected to that network.
For example, in a setup where the secondary storage system is connected to a
private network on the e0b interface, connect to the storage system and set the
ndmpd.preferred_interface to e0b, as follows:
Netapp3140a2> options ndmpd.preferred_interface e0b
ndmpd.preferred_interface e0b
In this way, the NDMP backup of all the snapshots that are replicated to that storage
system will use the private network.
In NetBackup, add NDMP host credentials to indicate the IP address or hostname
that is associated with e0b.
See “Authorizing NetBackup access to a NAS (NDMP) host” on page 90.

Restoring from a snapshot
About restores from array-based snapshots
File-level restore from the
snapshot
NetBackup directs the storage device to restore individual
files or folders from the snapshot. The storage device moves
the data on the storage device.
Several methods exist for file-level restore from a snapshot,
a replica, or a backup, as follows:
■
■
■
The Backup, Archive, and Restore interface.
See “Restoring files and folders from an array-based
snapshot” on page 98.
The NetBackup bprestore command.
For more information, see the NetBackup Commands
Reference Guide.
The Veritas OpsCenter interface.
See “Using OpsCenter to restore from array-based
snapshots” on page 103.
For more information, see the NetBackup OpsCenter
Administrator’s Guide.
Volume-level rollback restore NetBackup directs the storage device to replace the volume
from the snapshot (copy one) with the snapshot of the volume. The storage device may be
able to restore the volume without moving data.
See “How NetApp performs a volume-level rollback restore”
on page 103.
See “Restoring (rolling back) from an array-based snapshot”
on page 105.
Note: NetBackup supports snapshot restore of copy one
only to the primary site. To restore at a remote site, use
file-level restore.
Only a system administrator can perform an array-based restore.
Note: To restore from backups created using Replication Director: If you select
more than one image in the Backup, Archive, and Restore interface, it may take
longer than expected to display the contents of the images. NetBackup performs
a separate browsing operation for each selected image. For faster restores, select
one image at a time.

From a Replication Director snapshot of a virtual machine, you can restore the
following:
■
The entire virtual machine.

Restoring from a snapshot
About restores from array-based snapshots of virtual machines
See the topic on restoring the full VMware virtual machine in the NetBackup for
VMware Guide.
■
Individual files in virtual machines.
To restore virtual machine files, refer to the following topic.
Restoring files from array-based snapshots of virtual machines
Note: When you browse files to restore, the Backup, Archive, and Restore interface
displays the files and folders from the primary backup copy. A storage lifecycle
policy however can create several images or copies from one job. To restore files
from a different copy, set that copy as the primary. See the topic on how to promote
a backup copy to a primary copy in the NetBackup Administrator's Guide, Volume
I.
The initial steps for restoring individual files are described in the NetBackup for
VMware Guide.
Note the following when restoring files from Replication Director snapshots:
In the Backup, Archive, and Restore interface, under Files > Specify NetBackup
Machines and Policy Type, select VMware for the policy type.
If the SLP does not index the VM (or indexing is not complete), the BAR interface
browses the files directly from the hardware snapshot. The All Folders pane displays
an ALL_LOCAL_DRIVES node at the top level:
If the SLP was configured to index the virtual machine, the folders appear as follows
when the indexing is complete:
102
Restoring from a snapshot
Using OpsCenter to restore from array-based snapshots
Note: If you select an indexed snapshot and a non-indexed snapshot for the same
virtual machine, the folders appear twice under All Folders. Do not select files to
restore from two different images: the restore fails.
See “Configuring a policy for virtual machines to use Replication Director”
on page 185.
Using OpsCenter to restore from array-based
snapshots
Replication Director enables administrators to use the Restore operation in
OpsCenter to browse and restore files and directories from any copy of a snapshot
that is created as part of a storage lifecycle policy, even those in long-term storage.
The Restore operation in OpsCenter also offers greater flexibility with the advanced
search capabilities.
To use the Restore operation in OpsCenter requires that the Index From Snapshot
operation was used in the SLP that generated the snapshots and replications.
See “Index From Snapshot operation in an SLP” on page 62.
For more information about Operational Restore using OpsCenter, see the Veritas
NetBackup OpsCenter Administrator's Guide.
How NetApp performs a volume-level rollback
restore
NetBackup directs the array or storage device to do a volume-level rollback restore
(point-in-time restore) of the snapshot. The device determines how to accomplish
the restore.
103
Restoring from a snapshot
How NetApp performs a volume-level rollback restore
Several factors affect how the array accomplishes the restore, as follows:
■
Whether the rollback is from the most recent snapshot or not.
■
The NetBackup restore option: Force rollback even if it invalidates later
snapshots restore.
■
Whether the mount point from backup selection is a volume or qtree/folder in
the volume.
Note: Using NetApp storage, if a point-in-time rollback restore is performed for one
of the volumes in a backup image that consists of multiple volumes, the snapshots
corresponding to the remaining volumes will not be immediately deleted from the
storage system but they will be immediately removed from the NetBackup catalog.
Any subsequent image cleanup job will cause the remaining snapshots to be deleted
from the storage system.
Table 8-1 describes the interaction between the various factors.

Restoring (rolling back) from an array-based
snapshot
The following procedure describes how to perform a volume-level rollback restore
(point-in-time restore) from a snapshot that NetBackup Replication Director manages.
The storage device replaces the protected volume with the snapshot of the volume.
NetBackup supports point-in-time rollback restores for only NAS devices and only
for copy one. Point-in-time rollback restores are not supported for SAN devices on
Windows or UNIX.
Note: Do not perform a point-in-time rollback restore on a volume which is shared
across multiple policies because it retains the stale catalog entries for another policy
or policies.
See “About restores from array-based snapshots” on page 96.
See “How NetApp performs a volume-level rollback restore” on page 103.

■
Skip verification and force rollback
By default, NetBackup performs several checks on the file
system during the restore. If the checks fail, the restore stops.
Select this option to skip verification.
Warning: Select this option only if you are sure that you want
to replace all of the files in the original location with the
snapshot. Rollback deletes all files that were created after the
creation-date of the snapshot from which you restore.
■
Force rollback even if it invalidates later snapshots
This option applies only if you restore from a snapshot other
than the most recent one.
Warning: Select this option only if you are sure that you want
to replace the original volume with the snapshot. If more recent
snapshots that have been replicated exist and you do not select
this option, the rollback restore fails.

Veritas OpsCenter reporting
Use Veritas OpsCenter to provide unified reporting on Replication Director-related
activity. This includes monitoring the lifecycle of the snapshot copies at the various
storage locations. Administrators can use this information to help make
retention-related decisions.
Veritas OpsCenter offers the following reports:
■
Storage space utilization
■
Capacity planning reports that display forecasted and historical views.
All OpsCenter reports are described in the NetBackup OpsCenter Reporting Guide.
Configuring an alert for OpenStorage events
The administrator can configure OpsCenter to send alerts based on events on
OpenStorage devices (storage servers):
■
The storage server can generate threshold or Volume Almost Full alarms.
OpsCenter reporting
Storage lifecycle policy reporting
■
Alerts based on the auto-discovery of unprotected NAS file services data.
The alert policy can consider the following information before OpsCenter sends an
alert:
■
Whether the event is considered to be an error, an informational notification, or
a warning; or to consider all events regardless of classification. For example,
send alerts only when the storage server generates a warning.
■
Whether the event contains specific words or if it is generated by a specific
vendor. For example, send alerts that are generated only from the NetApp device
of label xyz.
■
Whether the event is from a specific master server; or to consider events from

Using NetApp disk arrays with Replication
Director
Replication Director can replicate snapshots on a NetApp disk array in two different
situations:
■
In non-cluster mode: 7-mode is used to replicate snapshots on NAS and SAN.
The plug-in must be installed on the OnCommand Unified Manager (OCUM)
server (Figure 10-1).
■
In cluster-mode: Clustered Data ONTAP (cDOT) is used to replicate snapshots
between storage virtual machines (SVMs or vServers). Support is for NAS only.
The plug-in must be installed on either a Windows or a Linux computer other
than the OCUM server, the master server, or any media servers (Figure 10-2).
Both modes support the same topologies.
Table 10-1 describes the association between NetBackup versions and the NetApp
plug-ins.

Determining the version of the plug-in
To determine the NBUPlugin version, look for the following version file on the system
where the NBUPlugin is installed:
On Windows: Install_path\Program Files\Netapp\NBUPlugin\version.txt
On UNIX: /usr/NetApp/NBUPlugin/version.txt
The contents of the file lists the product name, the build date, and the NBUPlugin
version. If more than one plug-in is installed, both are listed.
117
Using NetApp disk arrays with Replication Director
Supported NetApp topologies
Upgrading the plug-in
If upgrading the NetApp Plug-in for Veritas NetBackup, make sure that all storage
lifecycle policy jobs that use the old plug-in are complete before upgrading.
To determine whether all of the jobs that are associated with a storage lifecycle
policy are complete, in process, or not started, use the following command:
On Windows: install_path\NetBackup\bin\admincmd>nbstlutil.exe stlilist
-U
On UNIX: /usr/openv/netbackup/bin/admincmd/nbstlutil stlilist -U
Supported NetApp topologies
Table 10-2 describes the NetApp topologies that Replication Director supports.
Replication Director supports the same NetApp topologies for both cDOT and
7-mode. All begin with a snapshot of the data on the primary volume.

About using NetApp SAN-connected storage with Replication Director
Use Replication Director to back up NetApp block data on SAN-connected storage
using Fibre Channel or iSCSI.
If the same LUN is accessible through iSCSI and Fibre Channel, Fibre Channel is
used to mount the LUN.
If using the iSCSI protocol, establish sessions with the disk array using the CHAP
security protocol. The client and the alternate client may have sessions with different
users. The different sessions do not affect snapshot imports and restores, and do
not affect the following operations: Snapshot, Replication, and Backup From
Snapshot. If a session is already established on the alternate client, the LUN is
exposed to that host without any CHAP authentication.
See the following topics for iSCSI setup information:
■
See “Using SnapDrive for iSCSI setup on Windows” on page 129.

■
■
The following are not supported:
■
Windows boot file system on SAN.
■
RAW disks (on both Windows and UNIX).
■
Dynamic disks on Windows.
■
Fibre Channel over Ethernet (FCoE) protocol.
■
Point-in-time rollback restores are not supported when using SAN-connected

130
Using NetApp disk arrays with Replication Director
Using NetApp Data ONTAP 7-mode with Replication Director
If the OnCommand Unified Manager root or administrator password
has changed
If the root or the administrator password for the OnCommand Unified Manager is
changed, you must also perform the following actions:
■
Use the tpconfig command to update the storage server password in
NetBackup.
On Windows:
Install_path\Veritas\NetBackup\Volmgr\bin\tpconfig -update
-storage_server sshostname -stype server_type -sts_user_id UserID
-password Password
On UNIX:
usr/openv/volmgr/bin/tpconfig -update -storage_server sshostname
-stype server_type -sts_user_id UserID -password Password
The server_type is the vendor-provided string that identifies the type of storage
server. In the case of NetApp, enter Network_NTAP.
Note: The server_type is case-sensitive.
■
Restart the NBUPlugin service.
The processmanager command can be used.
On Windows:
Install_path\Program Files\NetApp\NBUPlugin\ProcessManager.exe
shutdown
Install_path\Program Files\NetApp\NBUPlugin\ProcessManager.exe
startup
On UNIX:
/usr/Netapp/NBUPlugin/processmanager shutdown
/usr/Netapp/NBUPlugin/processmanager startup
A replication job run after the password has been changed may fail with a status
83 (media open error) or a policy validation error of 4225. However, the job details
may indicate that the job ran successfully.
Considerations when configuring an OnCommand Unified Manager
as a NetBackup storage server
The following items are OCUM-specific and are helpful when configuring an OCUM
as a storage server.
131
Using NetApp disk arrays with Replication Director
Using NetApp Data ONTAP 7-mode with Replication Director
Storage server type
Select NetApp OnCommand server (7-mode) to create a storage server (for either
NAS volumes or SAN devices).
By default, the storage server has 5 minutes to communicate with NetBackup before
it times out. When creating a NetApp storage server (type NETWORK_NTAP),
more time may be required. To increase the timeout, edit the nbsl.xml file, the
configuration file that interacts with the NetBackup Service Layer process (NBSL).
Locate the nbsl.xml file in the following directory:
On Windows: C:\Program Files\Veritas\NetBackup\var\global\nbsl.xml
On UNIX: /opt/openv/var/global/nbsl.xml
Find the entry for TPCommandTimeout and change the default from 300 to a greater
value. For example:
TPCommandTimeout="600"
After making the change, restart the NBSL process so that the change takes effect.
Determining whether the OCUM server name is fully
qualified or short
Use the bpstsinfo command to verify whether a short name or a fully qualified
name is used for the storage server. The command is located in the following
directory:
■
Windows: Install_path\NetBackup\bin\admincmd\
■
UNIX: /usr/openv/netbackup/bin/admincmd/
Enter the bpstsinfo command as follows:
bpstsinfo -serverinfo -storage_server known_storage_server_name -stype
storage_server_type
For example, to ensure that the name of the OnCommand Unified Manager is
OCUMServer, enter the following command:
bpstsinfo -serverinfo -storage_server OCUMServer -stype Network_NTAP
Use the storage server name that is indicated in the output.

When the NBUPlugin is installed on the OnCommand Unified Manager, a
NetBackup group is automatically created on the OnCommand Unified Manager.
On the OnCommand Unified Manager, use the NetApp Management Console
to add resource pools to the NetBackup group so that the resource pools are
exposed to NetBackup. If the NetBackup group does not contain resource pools,
no LSUs display in the disk pool configuration wizard.
The available size that is listed is the total amount of space available in the pool.
The raw size is the total raw, unformatted size of the storage in the disk pool.
For OnCommand Unified Managers, the sizes on the primary volume always
display as 0 bytes, as indicated by a dash.
Importing existing NetApp relationships for NetBackup control
NetApp offers an import tool to migrate OnCommand Unified Manager data sets
and Data ONTAP relationships into NetBackup. Once in NetBackup, the snapshot
data can be managed using Replication Director.
The NetApp import tool allows the administrator to perform the following actions:
■
Export the data set configuration from the OnCommand Unified Manager into
an XML file.
■
Edit the XML file to change the backup policies or topology.
■
Import the XML file into NetBackup.
For more information on the import tool, see the NetApp Plug-in for Veritas
NetBackup Installation and Administration Guide, available from the NetApp Support
Site.
Enabling Unicode and language settings on NetApp disk arrays
Enable Unicode on each volume of the storage system. Use the NetApp vol
command options to enable convert_ucode and create_ucode on all NetApp
storage:
■
convert_ucode on
Forces the conversion of all directories to Unicode format.
■
create_ucode on
Forces the creation of Unicode directories by default.
Enable the volume language setting using UTF-8 so that the correct language
format is used for the NAS data.

Using NetApp Clustered Data ONTAP with Replication Director
Note: Replication Director does not support widelinks in a CIFS environment on
NetApp disk arrays.
Using NetApp Clustered Data ONTAP with
Replication Director
Replication Director for NetBackup 7.7 supports the NetApp Clustered Data ONTAP
operating system versions 8.2 and 8.3. Upgrade your master server, any media
servers, and any NetBackup clients to NetBackup 7.7 to protect the data in a
Clustered Data ONTAP environment using the existing Replication Director tools
and features.
Replication Director requires the NetApp OnCommand Unified Manager for Clustered
Data ONTAP 6.x for Clustered Data ONTAP support. The Clustered Data ONTAP
operating system lets you host Storage Virtual Machines (SVMs, formerly known
as Vservers). When you create backup policies in NetBackup, you work with volumes
on SVMs. Use Replication Director to protect volumes on SVMs with snapshot,
replication, and backup operations. You can replicate volumes to an SVM residing
on the same cluster as the source SVM or to a different cluster entirely (inter-cluster
replication).
NetApp developed an OST plug-in for Clustered Data ONTAP called the NBUPlugin
2.0. You install the NBUPlugin 2.0 to allow Replication Director to work with
Clustered Data ONTAP. The plug-in cannot be installed on the OnCommand Unified
Manager server, the master server, or any media servers. You must install the
plug-in on a separate Windows or Linux computer.

Considerations
Standard
For a Standard policy, make sure that the Storage Virtual Machine (SVM) can resolve
the NetBackup client’s host name by running the following command on the cluster
shell:
network ping -lif-owner vserver -lif lif-name -destination
NetBackup-client
When you create a mount point, you should keep the following in mind:
■
■
If the SVM name is used to create a mount point for a volume that is exported by
an SVM on the NetBackup client, you should enter the name of the SVM exactly
as the OnCommand Unified Manager sees it. If the SVM name in the OnCommand
Unified Manager is a fully qualified domain name, you must use the SVM's fully
qualified domain name when you create the mount point. The name is case-sensitive.
Alternatively, you can use the IP address of the SVM LIF to specify a mount point
instead of the SVM name.
Consider the following examples:
■
■
■
When you create a mount point on the NetBackup client for volume "vol_nfs" that
is exported by an SVM named "vs1", the nfs volume name must be specified as
"vs1:/vol_nfs".
You would use the command "mount vs1:/vol_nfs /mnt/vol_nfs".
If you specify the nfs volume name as "VS1:/vol_nfs" or "vs1.example.com:/vol_nfs"
then the snapshot job fails.
When you create a mount point on the NetBackup client for volume "vol_nfs2" that
is exported by an SVM named "VS2.example.com", the nfs volume name must be
specified as "VS2.example.com:/vol_nfs2".
You would use the command "mount VS2.example.com:/vol_nfs2 /mnt/vol_nfs2".
If you specify the nfs volume name as "vs2.example.com:/vol_nfs2" or
"VS2:/vol_nfs2" then the snapshot job fails.
When you create a mount point on the NetBackup client for volume "vol_nfs3" that
is exported by an SVM with the LIF "10.67.212.20", the nfs volume name must be
specified as "10.67.212.20:/vol_nfs3".
You would use the command "mount 10.67.212.20:/vol_nfs3 /mnt/vol_nfs3".
See “Configuring a Standard or MS-Windows policy to protect NAS volumes or
SAN-connected devices” on page 85.
Note: Replication Director for NetApp Clustered Data ONTAP supports NAS only at
this time.

Considerations
MS-Windows
For a MS-Windows policy, make sure that clocks are in sync for the following: the
domain controller that is used for the Storage Virtual Machine's (SVM) CIFS server
and the cluster hosting the SVM.
Make sure that the NetBackup Client Service and the NetBackup Legacy Client Service
are running under an account which has read and write access to the shares that the
SVM exports.
When you create a mount point, you should keep the following in mind:
■
■
If the SVM name is used to specify a share that is exported by an SVM in a policy,
you should enter the name of the SVM exactly as the OnCommand Unified Manager
sees it. If the SVM name in the OnCommand Unified Manager is a fully qualified
domain name, you must use the SVM's fully qualified domain name when you create
the mount point. The name is case-sensitive.
Alternatively, you can use the IP address of the SVM LIF to specify a share instead
of the SVM name.
Consider the following examples:
■
■
■
When you select a share "vol_cifs" that is exported by an SVM named "vs1" as a
backup selection, the selection must be entered as "\\vs1\vol_cifs".
If you enter the backup selection as "\\VS1\vol_cifs" or \\vs1.exqample.com\vol_cifs"
then the snapshot job fails.
When you select a share "vol_cifs2" that is exported by an SVM named
"VS2.example.com" as a backup selection, the selection must be entered as
"\\VS2.example.com\vol_cifs2".
If you enter the backup selection as "\\VS2\vol_cifs2" or
"\\vs2.example.com\vol_cifs2" then the snapshot job fails.
When you select a share "vol_cifs2" that is exported by an SVM with the LIF
"10.67.212.20" as a backup selection, the selection must be entered as
"\\10.67.212.20\vol_cifs3".

Standard or MS-Windows
with NDMP Data Mover
enabled
For a Standard policy with NDMP Data Mover enabled:
■
The Storage Virtual Machine (SVM) must be added as an NDMP host in NetBackup.
■
You should keep in mind the following naming conventions:
■ The junction name cannot be different from the volume name. When you mount
the volume in the SVM's namespace, make sure that the junction name is the
same as the volume name.
For example, if you have a volume "vol_nfs" on the SVM "vs1", you should use
the junction name "vol_nfs" when you mount the volume.
■ The mount path must use the host name as the SVM name. The SVM name
must be spelled out exactly as it appears in the OnCommand Unified Manager.
You cannot use the IP address of a data LIF when you mount an SVM's volumes.
For example, the mount point "/mnt/vol_nfs" on the NetBackup client refers to
"vs1:/vol_nfs", where vs1 is the SVM name and "vol_nfs" is the junction path
for the volume "vol_nfs".
For a Windows policy with NDMP Data Mover enabled:
■
The SVM must be added as an NDMP host in NetBackup.
■
You should keep in mind the following naming conventions:
■ Any share that is created as an export volume must have the same name as
the volume name.
For example, the volume "cifs_vol" on SVM "vs1" must be exported using the
share name "cifs_vol". The name is case-sensitive.
■ The share name must use the host name as the SVM name. The SVM name
must be spelled out exactly as it appears in the OnCommand Unified Manager.
You cannot use the IP address of a data LIF as the share name.
For example, the share "cifs_vol" on the SVM "vs1", must be specified as
"\\vs1\cifs_vol".

To generate a password for the NDMP user, run the following command:
vserver services ndmp generate-password –vserver vserver_name

■
Remote NDMP and three-way NDMP backups are supported for Clustered Data
ONTAP Backup From Snapshot operations. To perform three-way backup
operations, any devices and storage units must be configured for the tape devices
that are attached to the clustered storage system. You must add the NDMP host
using the cluster-management LIF in NetBackup. After the storage units are
configured for the cluster storage system, they can be used as the destination in
an SLP for three-way backups. Refer to the NetBackup NDMP Administrator's
Guide for more information.
Add the Storage Virtual Machine (SVM) as an NDMP host in NetBackup.
You must enter the SVM name exactly as the OnCommand Unified Manager sees
it when you create the policy. For example, if the SVM name in the OnCommand
Unified Manager is a fully qualified domain name, you must use the SVM's fully
qualified domain name when you create the policy. The entry is case-sensitive.
When you select a volume named "vol_nfs" that is on an SVM named "vs1" as a
backup selection, the selection must be entered as "/vs1/vol_nfs". Alternatively,
you can use the IP address of a LIF belonging to the SVM to configure a backup
policy for NDMP.
For the Backup From Snapshot operation to work correctly, make sure that an
Intercluster LIF is created on each node of the cluster.
■
■
You should enable a firewall policy for NDMP service on the Intercluster LIF:
■ You can use following NetApp command to verify that the firewall policy is
enabled for NDMP:
system services firewall policy show-policy intercluster
■
■
■
Make sure that the NDMP services are allowed for the "intercluster" policy. If
the "Allowed" column displays "0.0.0.0/0", it means that the firewall policy is
enabled and that all clients can connect to the NDMP service on the Intercluster
LIF.
If the firewall policy is not enabled for NDMP, use the following NetApp command
to enable it:
system services firewall policy modify -vserver cluster1
-policy intercluster -service ndmp 0.0.0.0/0
The destination SVM must be added as an NDMP host in NetBackup for Backup
From Snapshot to work from a replica.

If you use the ALL_FILESYSTEMS directive in an NDMP policy for Clustered Data
ONTAP, you must exclude the SVM's root volume using the
VOLUME_EXCLUDE_LIST directive.
For example, to exclude the root volume "root_vs1" of the SVM "VS1" you would
use the following directive:
VOLUME_EXCLUDE_LIST=/VS1/root_vs1
ALL_FILESYSTEMS
■
For more information, refer to the following topic:
See “ALL_FILESYSTEMS and VOLUME_EXCLUDE_LIST directives” on page 92.
To enable indexing, you must add a disk array host to NetBackup. Complete the
steps in the following procedure:
See “Configuring an NDMP policy to protect a NAS host” on page 78.
VMware
When you create an NFS datastore on a VMware ESX host and the datastore refers
to a volume that the SVM exported, the server name must be entered exactly as it
appears in the OnCommand Unified Manager. The server name entry refers to the
SVM name. This entry is case-sensitive. If the server name is not entered correctly,
the NetBackup snapshot job fails. Alternatively, you can use the IP address of the SVM
LIF to specify a server name instead of the SVM name.
If the NetBackup VMware host is a Windows computer, make sure that the appropriate
name-mapping rule is created on the SVM that exports the volume for the VMware
datastore. The name-mapping rule should map the user under which the NetBackup
Client Service is running to the UNIX user "root".
For example, SVM1 is a storage virtual machine that exports a volume to the ESX NFS
datastore. You should create a Windows-UNIX name-mapping rule on SVM1 that maps
the Windows user "DOMAINAME1\Administrator" to the UNIX user "root", where
"DOMAINAME1\Administrator" is the account for NetBackup Client service on the
VMware backup host. You should create similar name-mapping rules on any other
peer SVMs where replicated volumes are created.

Oracle
Oracle provides specific requirements for the mount commands that you use when
you mount Oracle database components to NetApp filers. Refer to your Oracle
documentation for more information. When you create a mount point for Oracle
operations, you must use an NFS version 3 volume. Make sure that the volume is
created using the parameters that are specified in the Oracle documentation.
Oracle backup policies may only include any data files that exist on the filer mount
point. Backup selections can include tablespaces, individual data files, or whole
databases so long as they exist on the filer mount point. If backup selections include
any file other than a data file or any files that do not exist on the mount point, the backup
operations fail.
Refer to the following topics for more information about configuring Oracle backup
policies:

Protecting volumes with nested junctions for Clustered Data ONTAP
When you snapshot or replicate volumes, any mounted volumes that reside under
the top-level volume are not necessarily protected. You should consider the following
example scenarios when you create backup policies for volumes with nested
junctions.
You may have a volume that is mounted under another volume, as in the example
below. Volume B is mounted under Volume A in the SVM VS1's namespace.

Replication Director does not support Infinite volumes.
■
NetApp Clustered Data ONTAP does not support qtree-level, SnapVault
replication. 7-mode supports qtree-level replication, however.
■
Clustered Data ONTAP SnapVault only supports volume level replication
The following limitations concern using Clustered Data ONTAP with NDMP:
■
NDMP Live Browse is supported with Clustered Data ONTAP 8.3 and higher
only.
For Clustered Data ONTAP 8.2, you can select the Index From Snapshot
option for any NDMP policies, so that you can search images for backed up
data.
■
Snapshot and Replication SLP workflows do not support NDMP backups to
local, node-attached tape devices.
■
Replication Director enabled NDMP policies only support any NDMP hosts that
are added using data LIFs. Any NDMP hosts that are added using
Cluster-management or Intercluster LIFs are not supported as Replication
Director enabled policies.
■
NDMP policies fail if you do not enter the SVM name exactly as the OnCommand
Unified Manager sees it when you create the policy. For example, if the SVM
name in the OnCommand Unified Manager is a fully qualified domain name,
you must use the SVM's fully qualified domain name when you create the policy.
The entry is case-sensitive.

Requirements for Oracle support
Oracle support for Replication Director allows the backup and restore of snapshots
of the Oracle database.
The following software is required:
■
Oracle Extension.
■
NetBackup Snapshot Client.
Currently, support is for NetApp NAS on UNIX platforms only.
The Oracle database must be installed on the NetApp disk array.
About Oracle support for Replication Director
Replication Director can be used to create snapshots of the Oracle database and
replicate the snapshots to other NetApp disk arrays. To use Replication Director,
the Oracle database must exist on a NetApp NAS disk array. (It is not supported
on SAN storage at this time.)
Oracle snapshot backups that use Replication Director are supported on UNIX
platforms only.

Description and notes
Make array-based snapshots Configure a storage lifecycle policy (SLP) and a backup policy to create array snapshots
of virtual machines on NFS
of virtual machines. The snapshots remain on the array or filer (NetBackup storage
datastores
server) and are not backed up to a NetBackup media server storage unit. This type of
backup is the foundation for the other Replication Director operations.
Note the following:
■
The snapshots are created on NFS datastores only.
■
The virtual machine or its individual files can be restored directly from the snapshots
on the storage server. The snapshots can also be replicated to other locations.
For faster browsing of files to restore, include the Index From Snapshot option in
the SLP. This option catalogs the metadata of the virtual machine.

■
■
■
To restore files from a replica of the snapshot, the replica must exist in the same
NetBackup domain as the snapshot.
To restore files to the original virtual machine, a NetBackup client must be installed
on the original virtual machine.
As an alternative, you can use an alternate client to restore to a shared UNC location.
You must manually copy the files back to the original location.
See the topic on restoring individual files in the NetBackup for VMware Guide.
To restore multiple directories that have named streams, the Windows NetBackup
client on the destination virtual machine must be at 7.6 or later.
For setting up Replication Director for virtual machines, the initial steps are the
same as Replication Director for physical computers as follows:
■
Verify that your backup environment contains the necessary hardware and
software to configure and run Replication Director. Make sure you can
successfully back up a physical computer with Replication Director.
Note: NDMP is not required for Replication Director and virtual machines.
■
Install or upgrade NetBackup.
■
Configure the following:
■
The disk array storage of the OpenStorage partner.
■
The NetBackup storage server.
■
The disk pool(s).
■
The NetBackup storage lifecycle policy (SLP).
Create a new operation in the SLP for each task that the SLP is to perform.
For example, create a snapshot operation to perform the snapshot and a
replication operation to copy the snapshot.

Notes on Replication Director for virtual machines
Note the following about Replication Director for virtual machines:
■
For supported vCenter versions and datastores, see the NetBackup Software
Compatibility List available from the following location:
NetBackup Master Compatibility List
■
For additional support details, see the following Veritas tech note:
Support for NetBackup 7.x in virtual environments
■
Replication Director for virtual machines does not support Accelerator.
■
Instant Recovery supports disk storage units only. To use Instant Recovery to
restore a VM that was backed up with Replication Director for virtual machines,
note: The virtual machine backup must have been copied to a disk storage unit.
■
Although applicable to Replication Director for physical computers, NDMP backup
does not apply to Replication Director for virtual machines.
■
Replication Director supports virtual machines on NetApp NFS datastores only.
■
To create virtual machines on the NFS datastore, enter anon=0 in the
/etc/exports NetApp file on the NetBackup storage server. The anon=0 entry
is the equivalent of the no_root_squash option. See the following VMware
document for more information on the anon=0 entry:
183
Using Virtual Machines with Replication Director
About virtual machines and Replication Director
Best Practices for running VMware vSphere on Network Attached Storage
■
The NetApp OnCommand Unified Manager (formerly DataFabric Manager) must
be able to resolve the host name that was used to mount the vCenter datastore.
Hardware snapshots cannot succeed if the OnCommand server is unable to
resolve the host name
■
If the NetBackup master and media server are UNIX and the backup host is
Windows, the backup host must have a fully qualified domain name. Otherwise,
the backup fails.
■
You must have a valid NFS export (share) for each qtree that is mounted as an
NFS datastore.
■
Supports restore of virtual machines and of individual files in virtual machines.
Does not support volume-level rollback restore. (In the Replication Director
Solutions Guide, references to rollback restore do not apply to virtual machines.)
■
If the datastore name contains special characters, the datastore name in the
backup image contains @ followed by the value of the special character. For
example, a datastore that has the name “NFS datastore1” (with a space) appears
in the NetBackup catalog as NFS@20datastore1.
■
If changes occur to virtual machine configuration (such as adding, deleting, or
moving VMDKs), it may be necessary to set Reuse VM selection query results
for to 0. (Reuse VM selection query results for is on the policy Clients tab.)
With a setting of 0, NetBackup rediscovers the virtual machines and their
configuration each time the policy runs. Note: If the vmdk files are reconfigured
and the next backup runs without rediscovery, NetBackup is not aware of the
vmdk changes. It attempts to back up the virtual machines in their previous
configuration. The result may be an incorrect backup.
■
VMware vSphere uses the Space Efficient Virtual Disk (SEsparse) for snapshots
of the disks that are larger than 2 TB. VMware's VDDK however does not support
backup or restore of SEsparse disks with the host-based file transport mode.
Because Replication Director for VMware requires host-based file transport,
Replication Director cannot support the vmdk files that are larger than 2 TB. To
back up the vmdk files that are larger than 2 TB, use NetBackup for VMware
without Replication Director.
■
When restoring from Replication Director backups, note the following:
■
If you select more than one image in the Backup, Archive, and Restore
interface, it may take longer than expected to display the image contents.
NetBackup performs a separate browsing operation for each selected image.
You should select one image at a time when browsing for restore.
■
Do not select files or folders from two different images. The NetBackup
Backup, Archive, and Restore interface, and the OpsCenter interface do
184
Using Virtual Machines with Replication Director
About virtual machines and Replication Director
not support restoring data from two different images in the same restore job.
Restore from one image at a time.
When you use the Backup, Archive, and Restore interface to browse for
an image to restore, only the primary copy is made available for restore. In
the NetBackup Administration Console, use the Catalog node to select
a different copy (such as a backup image or replica) as the primary copy.
■
Note: NetBackup automatically selects the correct hardware (datastore)
snapshot to restore, based on the virtual machine snapshot that is designated
as the primary copy. Make sure the virtual machine snapshot that you want
to restore is set as the primary.
See “About jobs in the Activity Monitor that use Replication Director for virtual
machines” on page 188.

About jobs in the Activity Monitor that use Replication Director for
virtual machines
You can use the NetBackup Activity Monitor to keep track of virtual machines
backups as they occur. The number of jobs that appear in the Activity Monitor
depends on the policy's Application Consistent Snapshot option.
Note: The Application Consistent Snapshot option is enabled by default. In most
cases, Veritas recommends that you keep this option enabled. If this option is
disabled, data in the virtual machine may not be in a consistent state when the
snapshot occurs.

Backup
The process of creating a copy of user data and creating backup images of the data.
■
The process of creating a new tar-formatted backup image of the client's data.
■
The process of creating a snapshot of the client's data.
Cluster Data ONTAP
The operating system that is used on NetApp storage systems in a clustered mode.
Copy
An instance of a NetBackup image which can standalone; it can be read or deleted without
affecting any other copy.
Data mover
The mechanism that is used to copy data from storage on the production client to backup
storage. Or, to duplicate, the data mover copies data from backup storage to different backup
storage.
Traditionally, NetBackup functions as the data mover and data travels through clients and
media servers. Storage devices can provide more efficient mechanisms to move the data,
such as NDMP, built-in replication, or OST (as in Optimized Duplication).
Data ONTAP
The operating system that is used on NetApp storage systems in 7-Mode.

Definition
Disk array
A disk array which exposes storage or network shares to a host server over SAN, NFS, CIFS,
or iSCSI protocols.
Duplication
NetBackup creates a copy by using a media server to move the data or by using the optimized
duplication method.
Local domain
The domain in which the storage device resides and in which it is configured.
Mirror
This term can mean either of the following:
■
■
Mount host
A disk that maintains an exact copy (duplicate or replica) of another disk. A mirror disk is
often called a secondary, and the source disk is called the primary. All writes to the primary
disk are also made to the mirror disk.
A type of snapshot that is captured on a mirror disk. At the appropriate moment, all further
writes to the primary disk are held back from the mirror, which splits the mirror from the
primary. As a result of the split, the mirror becomes a snapshot of the primary. The
snapshot can then be backed up.
The host on which NetBackup mounts a snapshot when NetBackup needs to access the
snapshot for any reason. Typically, NetBackup accesses the mount host to browse or to
restore backups, or to perform either an Index From Snapshot or a Backup From Snapshot
operation in a storage lifecycle policy.
To mount a snapshot on a host other than the production client is generally more efficient
because it avoids a negative impact on the performance of the production client. Media
servers make excellent mount hosts because the media server is both a client and a media
server (data mover). As such, NetBackup can often avoid an additional network hop. If no
compatible media servers exist, dedicated clients are the next best choice.
Note: The mount host and the production client must run the same operating system for the
mount host to access the production client. The mount host must be at the same OS version
or later.
See the NetBackup Snapshot Client Administrator's Guide for more details.
NetApp Plug-in for

OST device
A storage server that has implemented the OST plug-in interface.
Point-in-time rollback
A snapshot is a point-in-time, disk-based copy of a file system or volume. A restore from a
snapshot rolls the entire file system or volume back to a specific point in time. Therefore, a
snapshot restore is called restoring from a Point-in-time rollback. All of the data in the snapshot
is restored. Any data changes or snapshots that were made after that point-in-time are lost.
Primary volume
A unit of storage space that a disk array exposes to a host in the form of a network share
(NFS or CIFS) or LUN block device. Primary volumes store an application’s active data.
Replica
A replica is a block copy of the snapshot.
Replication
The process of replicating a snapshot onto a separate disk array using NetBackup Replication
Director.
Replication source
A NetBackup-configured disk pool and storage unit that contains the volumes that serve as
the source for subsequent replications.
Replication target
A NetBackup-configured disk pool and storage unit that can receive or accept replications
from a replication source.
Snapshot
A point-in-time, read-only, disk-based copy of a client volume or of a filer. A snapshot is
created with minimal impact on other applications. NetBackup provides several types of
snapshots, depending on the device where the snapshot occurs.
An image copy that is a snapshot is also considered a replica. A snapshot copy consists of
one or more snapshot fragments.
Snapshot method
A set of routines for creating a snapshot. The NetBackup administrator can select the method,
or let NetBackup select it when the snapshot begins (auto method).
Snapshot mirror
A disk mirror that is an exact replica of a primary volume at a particular moment, reproduced
on a physically separate device.
Snapshot source
The production data (file system, raw partition, or logical volume) to which a snapshot method
is applied. NetBackup automatically selects the snapshot source according to the entries in
the Backup Selections list of the snapshot policy.
