Purpose of the Guide (see page 10)
Introduction to the Enterprise Module
CA ARCserve Backup is a distributed comprehensive storage solution for
application, databases, distributed servers, and file systems. It provides backup
and restore capabilities for databases, business-critical applications, and
network clients.
The CA ARCserve Backup Enterprise Module (Enterprise Module) is a
separately-installed component that includes the following options and features:
■
Multistreaming: two or more streams of backup data.
■
Disk staging backups and tape staging backups with multistreaming and
transmit three to 32 streams of backup data.
Note: If you do not license the Enterprise Module, CA ARCserve Backup lets
you transmit two streams of backup data for disk staging and tape staging
backup jobs, and one stream for custom backup jobs. A "custom" job is a job
that does not utilize a rotation schedule, a grandfather-father-son (GFS)
rotation, or media pools. For more information, see the Administration
Guide.

Chapter 2: Image Option
This section contains the following topics:
Introducing the Image Option (see page 11)
Installing the Image Option (see page 13)
Using the Image Option (see page 14)
Introducing the Image Option
CA ARCserve Backup offers the Image option, which backs up data at a high
speed. The option bypasses the file system, creates a snapshot image of the
drive, and reads data blocks from the disk. The option treats the entire drive like
a single file, and replaces the traditional method of traversing the file system
file-by-file.
The option provides device independence. It writes to any device supported by
CA ARCserve Backup, including media devices, media libraries, and media RAID
devices.
Using the CA ARCserve Backup Image Option, you can do the following:
■
Scan files to optimize performance. During this process the drives are
scanned, and the information about the files present on the drive is used to
optimize backup and restore performance.
■
Perform optimized image drive level backup and restore operations. When
backing up and restoring at the drive level, the option bypasses the file
system to optimize the process.
■
Restore individual files as well as full drives. The option can restore data at
the file level and at the drive level.
■
Back up both Windows NT File System (NTFS) and File Allocation Table (FAT)
file systems. In addition, back up NTFS with compressed and encrypted files,
directories, and drives.
■
Maintain all of the file information, such as file name, file size, date, and
security.
Chapter 2: Image Option 11
Introducing the Image Option
How the Option Works
The CA ARCserve Backup Image Option performs a backup job in two phases.
1. Scanning phase
The option collects information about all of the files on a drive including file
name, file size, date, time, attributes, clusters used by the file, file security
attributes, and any other information required to back up the file during the
backup phase.
File Scanning is always enabled for FAT/FAT32. File scanning for NTFS is only
done when Enable File Level Restore is selected from the Image/Serverless
Backup Options dialog. The option still does a minimal scan of the drive to
find the occupied drive spaces to back up.
2. Backup phase
The CA ARCserve Backup Image Option backs up data in this phase. The
backup engine reviews the information from the scanning phase, and then
streams the data as fast as possible on to the backup media.
12 Enterprise Module Guide
Installing the Image Option
Backup Method
The CA ARCserve Backup Image Option backs up data by taking a snapshot of
the drive at a specific point in time. Although the drive appears to be frozen at a
particular time, it functions normally and lets other applications send read and
write requests. This feature is known as the Snapshot feature, and it is
automatically installed when you install the option.
This method has the following advantages:
■
At the start of the backup process, the option does not attempt to lock the
drive about to be backed up.
■
If applications write to the drive while a backup operation is in progress, the
integrity of the backup data is maintained at all times. The backup operation
continues and is successful even when files are being written to during the
backup process.
Installing the Image Option
To install the Image option, you should be familiar with the characteristics and
requirements of the specified Windows operating systems, and with
administrator responsibilities on those operating systems.
Installation Prerequisites
Before installing the option, verify the following:
■
Your system configuration meets the minimum requirements needed to
install the option.
For a list of requirements, see the readme file.
■
You have administrator privileges on the computers on which you want to
install the option.
■
You have the following applications installed and working properly:
–
CA ARCserve Backup
–
CA ARCserve Backup Enterprise Module
Important! You must install the Enterprise Module (which automatically
includes this option) and CA ARCserve Backup on the same computer. This
computer can be located either locally or remotely.
Chapter 2: Image Option 13
Using the Image Option
Install the Image Option
The Image Option is installed locally when you install the Enterprise Module.
To install and configure the option
1. Install and configure the option using the Enterprise Module Configuration
utility (EMConfig.exe) during the post-installation process.
Note: You can also access the EMConfig.exe utility from the Windows Start
menu (click Start, All Programs, CA, ARCserve Backup, Enterprise Module
Configuration).
2. Complete the installation and configuration procedure, and restart your
computer when prompted.
Post-Installation Tasks
You must complete two post-installation tasks before you start using the CA
ARCserve Backup Image Option:
■
Verify that the driver for the CA ARCserve Backup Image Option is loaded
successfully by checking the registry key for the presence of the driver. An
example of a registry key location is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hbmnt
■
After rebooting, check the Windows Event Viewer to ensure that the driver
HBMNT5.SYS loaded successfully. The driver is installed in the following
location:
[System Root]\System32\drivers\hbmnt5.sys
Using the Image Option
This section explains how you can use the CA ARCserve Backup Image Option
Backup Manager to configure your backup jobs and restore data.
14 Enterprise Module Guide
Using the Image Option
General Considerations
To run successful backup and restore jobs, consider the following:
■
Keep some empty space on the drive where the option is installed. Because
the option creates logs and temporary files to enhance performance, it needs
space on this drive. Ideally, 15-20 MB free space should be sufficient.
■
To accommodate the Snapshot feature, the option creates a temporary
storage file on a local drive that has the greatest amount of free space
available. In addition to the 15-20 MB free space suggested in the previous
point, you must have at least 20 MB free for the Snapshot feature.
■
While restoring an active system drive, you must have at least 50 MB
available on the drive. This amount of space is needed to store additional
temporary files and registry files when you back up and restore data.
Backup Job Definition
You can use the Backup Manager to configure and set up your backup jobs. You
can back up an image only on a computer where CA ARCserve Backup and the
option are both installed.
You can back up a partition to a File System Device. The File System Device can
be on the same partition, but the backup job may fail if the other drives do not
have sufficient disk space. We recommend that you have the File System Device
on a different drive.
During backup, the Snapshot feature is required to freeze the drive. The drive is
then synchronized, which means that it waits for a period when nothing is being
written to the drive. If this write-inactivity period cannot be found, the
synchronization times out after a specified time and the freeze request fails. The
inactivity period is the number of seconds of inactivity on the drive before the
drive is deemed safe to freeze.
Chapter 2: Image Option 15
Using the Image Option
To change the default registry value for SyncTimeout, InactivityPeriod, and
PreviewFilename, you must create the following key and set the values for these
parameters:
Software\ComputerAssociates\CA ARCserve Backup\Base\TapeEngine\Image
While SyncTimeout is 80 seconds by default, the Inactivity Period is 3 seconds by
default.
If the registry contains a value and a key for PreviewFilename, the path name
identifies the location of the preview file. If the file name is not specified, the
path name identifies the volume that contains the most free space and is on a
drive that is not being backed up. (If there is only one drive, the path name
identifies the only drive). If the PreviewFilename specifies one or more
subdirectories, the subdirectories will automatically be created.
Note: There is no attempt to validate the directory. During backup, if the
directory cannot be accessed or created (usually due to an invalid volume), the
backup job fails.
The global backup option, Encryption is not supported at this time.
16 Enterprise Module Guide
Using the Image Option
Define Backup Jobs Using the Backup Manager
You can use the Backup Manager to configure and set up your backup jobs.
To configure and set up backup jobs
1. Open the Backup Manager and select the Source tab.
All sources available for backup are listed in the left pane.
Note: To successfully complete a backup job using the Backup Manager, you
must select an entire drive on the computer that you are backing up.
2. Right-click on a computer node listed in the Source tab of the Backup
Manager and select Use Image/Serverless Backup Option.
The Image/Serverless Backup Options dialog opens.
3. Complete the fields in the dialog, and then click OK.
4. Right-click a disk node listed in the Source tab of the Backup Manager and
select Use Image/Serverless Backup Option.
The Image/Serverless Backup Options dialog opens.
5. Repeat steps 3 and 4.
You have configured and set up your backup jobs with the help of Backup
Manager.
For more information on backing up using the Backup Manager, see the online
help.
Chapter 2: Image Option 17
Using the Image Option
More information:
Image/Serverless Backup Option Dialog (see page 18)
Image/Serverless Backup Option Dialog
The Image/Serverless Backup Options dialog lets you configure a backup job.
The Image/Serverless Backup dialog displays the following fields:
These settings take precedence over machine options
Indicates that the settings on this dialog override any options that you may
have set on the disk or volume.
Enable Image/Serverless Backup for this drive/volume
Sets values for the entire computer.
The dialog has the following options:
Enable file level restore (Slows down backups for NTFS volumes)
Enables restoring at the file level. However, this slows down the process
when you back up NTFS volumes, because the IO has to generate the
file/folder information by parsing the file system layout on the disk.
Add file records to database
Adds details of files to the database. This is helpful when you choose to
enable restoring at file level, as the backup sessions will have the details of
files in the database. If you do not add these details to the database, when
you restore at the file level, you will have to merge the backup sessions with
the file details before restoring.
18 Enterprise Module Guide
Using the Image Option
The following fields let you specify the action when a volume freeze fails:
Fail backup immediately
Stops the backup process when a volume freeze fails.
Continue with backup

Chapter 2: Image Option 21
Using the Image Option
Restore Methods
Use one of the following methods to restore data backed up by the CA ARCserve
Backup Image Option:
■
Restore by Image
Restores the entire drive in one pass. To be successful, the restore job must
be completed from beginning to end. Canceling leaves the drive in an
inconsistent stage, and therefore inaccessible. The following are the
limitations of this method:
–
The Restore by Image method supports only full volume restores. When
you use the Restore by Image method, the agent overwrites the target
volume, so be sure that the target drive selected is the one that you want
to restore.
Important! The Restore by Image option overwrites your drive
completely. Be sure this is what you want to do.
22 Enterprise Module Guide
–
In the Restore by Image method, selecting multiple sources is only
permitted when using the Restore to Original Location option.
–
The Restore by Image method supports cluster sizes up to 16 KB for
NTFS partitions, and requires multiple drives or partitions to function
properly. This option does not support single partitions.
–
The Restore by Image method always overwrites existing files during
restore operations, regardless of the restore options selected.
Using the Image Option
■
–
The Restore by Image sessions cannot be restored to network drives.
They require the same or greater local hard disk drive.
–
During a Restore by Image session, the drive cannot have any open files.
The option attempts to lock the drive before the restore process begins,
and, if any files are open, the drive cannot be locked and the restore job
fails.
Restore by Session
Restores individual files and directories. Canceling a job that is in progress
can leave many incomplete restored files on the drive.
The following global restore options are not supported at this time:
■
Destination
Directory Structure and File Conflict Resolution
■
Operation
Restore Registry Files and Event Logs
■
Virus
Enable Virus Scanning, Skip, Rename, and Delete
The CA ARCserve Backup Image Option does not support the Restore by Backup
Media method at this time.
Restore a Drive
CA ARCserve Backup restores the entire drive backed up by the CA ARCserve
Backup Image Option.
To restore a drive
1. Open the Restore Manager.
2. On the Source tab, select the Restore by Image/Serverless option in the
drop-down list.
3. Select the drives containing the backup taken using the option.
4. (Optional) On the Destination tab, select the destination where you want to
restore.
5. Click Submit on the toolbar.
The restore process starts or is scheduled to be executed.
Chapter 2: Image Option 23
Using the Image Option
Restore Individual Files
CA ARCserve Backup restores individual files backed up by the CA ARCserve
Backup Image Option.
To restore individual files
1. Open the Restore Manager.
2. On the Source tab, select Restore by Session from the drop-down list.
The sessions appear in the session directory tree.
3. Select the files, folders, or both that you want to restore.
(Optional) On the Destination tab, clear the check mark next to Restore files
to their original location(s) and then specify the location where you want to
restore the data.
Click Submit on the toolbar.
The restore process starts or is scheduled to be executed.

Chapter 3: Serverless Backup Option
This section contains the following topics:
Introducing the Serverless Backup Option (see page 25)
Installing the Serverless Backup Option (see page 29)
Using the Serverless Backup Option (see page 30)
Introducing the Serverless Backup Option
Among the options CA ARCserve Backup offers is the CA ARCserve Backup
Serverless Backup Option. This option helps you do the following:
■
Back up data with near-zero impact to the system CPU.
■
Let applications on servers continue to run while the backup job is in
progress.
■
Eliminate the need for a backup window, ensuring the highest possible
backup and restore performance.
■
Let applications continue to access the data while the data is being backed
up.
The Serverless Backup Option is implemented using the extended copy
command and currently supports SAN environments with devices that support
this command.
Backup Methods
The following sections describe the different backup methods available in the
Serverless Backup Option.
Chapter 3: Serverless Backup Option 25
Introducing the Serverless Backup Option
Traditional Server-Based Backup
In traditional backup operations, the backup application reads the data from the
primary storage device to the system memory, and does the necessary
formatting. It then sends the data back to the media storage devices, requiring
use of CPU, I/O channels, and the system memory. The data path is illustrated in
the following diagram:
Typically, when backup operations are in progress, application processing on
servers is impacted. This is one of the reasons for which system administrators
prefer to perform backup operations at a time when the application load on the
server is at a minimum.
SAN Backup
SANs have improved system administration by addressing the potential
limitations of traditional backup operations. In traditional backup operations,
one network server is connected to a device and, as a result, is the only server to
receive the benefits of high-speed backup operations. SANs allow several
servers to directly link to a device, thus eliminating the LAN bottleneck and
slower transmission.
SANs improve backup operations by:
■
Centralizing backup hardware and media
■
Economizing by allowing servers to share multiple tape libraries
■
Reducing processing time by eliminating the need for remote backup
operations
26 Enterprise Module Guide
Introducing the Serverless Backup Option
The basic SAN architecture is shown in the following diagram:
High Performance Serverless Backup
SANs incorporate various devices referred to as data movers. These devices
support the extended copy (or sometimes called third party copy) command.
The Serverless Backup Option uses these data movers to extend SAN technology
by facilitating the fastest possible backup and restore speeds.
Using the extended copy command, the option completely eliminates the server
from the data transfer path and achieves direct disk-to-media or media-to-disk
data transfer. Initiating the data transfer is the only activity that occurs at the
server level; the actual data transfer occurs at the level of the data mover on the
SAN. Serverless operation is illustrated in the following diagram:
The Serverless Backup Option uses data movers to transfer data between media.
This eliminates the need for moving the data to the server, and achieves the
shortest data path. Data movers enhance the backup performance considerably,
and yield the highest possible backup and restore speeds.
The option freezes the backup drive at a consistent point in time (like a
snapshot), but still allows applications to continue to access volumes while the
backup job is in progress. This functionality eliminates the need to schedule
backup jobs when the application load on the server is at a minimum, and lets
system administrators back up data at any time.
Chapter 3: Serverless Backup Option 27
Introducing the Serverless Backup Option
Unsupported Functions
The following CA ARCserve Backup functions are not available when using the
Serverless Backup Option:
■
The CA ARCserve Backup Tape RAID Option
■
The CA ARCserve Backup Disk Staging Option
■
Filters for backup
■
Multiplexing
■
Virus scan
■
Encryption
Operational Considerations
The Serverless Backup Option allows you to perform serverless backup and
restore of hard drives in a SAN environment, with the following considerations:
■
The option does not support restore using the Restore by Media method.
■
The option supports full volume backup in serverless mode.
■
The option supports full volume restore using the Restore by
Image/Serverless method.
Note: Because serverless backup is a full volume backup, you will overwrite
the target volume if you use the Restore by Image/Serverless from the
Restore Manager. You must make sure that the target drive you have
selected is the one you really want to restore.

Using the Serverless Backup Option
Image/Serverless Backup Option Dialog
The Image/Serverless Backup Options dialog lets you configure a backup job.
The Image/Serverless Backup dialog displays the following fields:
These settings take precedence over machine options
Indicates that the settings on this dialog override any options that you may
have set on the disk or volume.
Enable Image/Serverless Backup for this drive/volume
Sets values for the entire computer.
The dialog has the following options:
Enable file level restore (Slows down backups for NTFS volumes)
Enables restoring at the file level. However, this slows down the process
when you back up NTFS volumes, because the IO has to generate the
file/folder information by parsing the file system layout on the disk.
Add file records to database
Adds details of files to the database. This is helpful when you choose to
enable restoring at file level, as the backup sessions will have the details of
files in the database. If you do not add these details to the database, when
you restore at the file level, you will have to merge the backup sessions with
the file details before restoring.
The following fields let you specify the action when a volume freeze fails:
Fail backup immediately
Stops the backup process when a volume freeze fails.
Continue with backup
Continues with the backup process although a volume freeze has failed.
Retry specified number of times then fail backup
Attempts to continue the backup process for a preset number of times.
Number of retries
Specifies the number of times that the option attempts to complete the
backup process.
Interval between retries (mins)
Specifies the number of minutes that the option waits after a failed
backup attempt.

Introducing Enterprise Tape Library 3494 and StorageTek
ACSLS
CA ARCserve Backup offers two solutions for tape libraries, namely the CA
ARCserve Backup Enterprise Option for IBM 3494 and the CA ARCserve Backup
Enterprise Option for StorageTek ACSLS. These options let you use the large
tape volume capacities of the IBM® TotalStorage® Enterprise Automated Tape
Library 3494, and the tape libraries controlled by StorageTek Automated
Cartridge System Library Software (ACSLS) Manager software. CA ARCserve
Backup server interfaces with the IBM TotalStorage Enterprise Automated Tape
Library 3494 and StorageTek Automated Cartridge System Library Software to
manage backup and restore operations, tape volume movement, and tape
volume organization.
This section uses the following conventions:
Enterprise Tape Library 3494

the option
Identifies Enterprise Option for IBM 3494 or Enterprise Option for
StorageTek ACSLS in general.
tape library
Identifies Enterprise Tape Library for 3494 or StorageTek ACSLS in general.
The options let several CA ARCserve Backup servers share a network-connected
tape library. By using several CA ARCserve Backup servers, you can divide large,
complex backup requirements into manageable subsets and maximize backup
and restore efficiency. Backup and restore jobs run simultaneously on all CA
ARCserve Backup servers with complete storage data integrity.
These options also provide services that let CA ARCserve Backup perform
backup, restore, and device management operations on the tape volumes. Each
CA ARCserve Backup server performs these operations as if it is controlling its
own separate library. CA ARCserve Backup server interprets the assigned tape
volumes on the tape library as local tape volumes; however, the physical
movement of tape volumes is managed exclusively by the tape library.
Important! The tape volumes in the tape library must have bar codes to use the
option.
36 Enterprise Module Guide
Introducing Enterprise Tape Library 3494 and StorageTek ACSLS
Enterprise Tape Library IBM 3494
After you install and configure the Enterprise Option for IBM 3494 on the CA
ARCserve Backup server, you can use CA ARCserve Backup to manage backup
and restore operations on the Enterprise Tape Library 3494.
Using the Enterprise Option for IBM 3494, the CA ARCserve Backup server can
automatically associate known or discovered physical tape drives in the
Enterprise Tape Library 3494 with a logical local library on the CA ARCserve
Backup server. The option lets you assign tape volumes in the Enterprise Tape
Library 3494 to the logical library on the CA ARCserve Backup server. This
configuration lets you use the features of CA ARCserve Backup to control the
Enterprise Tape Library 3494.
Note: Each CA ARCserve Backup server can be physically connected to one
Enterprise Tape Library 3494 and can manage one logical library configuration
for the Enterprise Tape Library 3494.
Chapter 4: Enterprise Tape Library 3494 and StorageTek Options 37
Option Architecture
StorageTek ACSLS
After you install and configure the Enterprise Option for StorageTek ACSLS on
the CA ARCserve Backup server, you can use CA ARCserve Backup to perform
the following functions:
■
Manage backup and restore operations
■
Update the configuration of the virtual library on the CA ARCserve Backup
server with device or tape volume changes on the StorageTek ACSLS tape
library
The Enterprise Option for StorageTek ACSLS lets several CA ARCserve Backup
servers share a network-connected StorageTek ACSLS tape library. StorageTek
ACSLS functions as a central service provider for StorageTek ACSLS library
operations in heterogeneous environments. This configuration lets you manage
different application-dedicated libraries using one centralized library or string of
libraries.
Note: The term mixed media (or heterogeneous environment) refers to a
mixture of tape drives and tape volumes in the StorageTek ACSLS tape library.
In configurations where more than one tape drive is connected to a CA ARCserve
Backup server, both tape drives must use media of the same type.
Using this option, the CA ARCserve Backup server can assign tape volumes in the
StorageTek ACSLS tape library to the logical library on the CA ARCserve Backup
server. This virtual library configuration lets you use the features of CA ARCserve
Backup to control the remote StorageTek ACSLS tape library as if it were
connected locally.
Note: Each CA ARCserve Backup server can manage one logical library
configuration for the StorageTek ACSLS tape library. Each CA ARCserve Backup
server can physically connect to multiple tape drives of the same type.
Option Architecture
This section describes the architecture of each tape library.
The options are separate software components installed on servers running CA
ARCserve Backup. Several CA ARCserve Backup servers can share one tape
library.
While the CA ARCserve Backup server logical library essentially partitions a large
Enterprise Tape Library 3494 into independent, user-defined logical libraries, the
CA ARCserve Backup server virtual library essentially partitions a large
StorageTek ACSLS tape library into independent user-defined logical libraries.
38 Enterprise Module Guide
Option Architecture
Enterprise Tape Library 3494
The tape volume assignments on the CA ARCserve Backup server define the
logical library. The tape volumes configured for the Enterprise Option for IBM
3494 are not part of a physical library connected to the CA ARCserve Backup
server, but are interpreted by CA ARCserve Backup as a local library. The logical
library configurations have a mutually exclusive set of tape volumes or a shared
set of tape volumes, depending on whether the CA ARCserve Backup server is in
a SAN.
Note: In configurations where multiple backup servers share the Enterprise
Tape Library 3494, ensure that tape drives assigned to CA ARCserve Backup
server are not assigned to any other backup servers.
Communication Interface
Each backup server communicates directly and independently with the
Enterprise Option for IBM 3494. Although multiple backup servers may exist on
the same network, CA ARCserve Backup servers do not communicate with other
backup servers.
Note: For more information about using CA ARCserve Backup in a SAN, see
Appendix A: Storage Area Network Support in the Administration Guide.
Communication between the Enterprise Tape Library 3494 and the CA ARCserve
Backup server occurs through the following communication interfaces:
■
The IBM Automated Tape Library service on the CA ARCserve Backup server
connects to the Enterprise Tape Library 3494 through an Ethernet LAN
control path.
■
Each CA ARCserve Backup server independently connects to one or more
tape drives in the library through SCSI or fiber channel data paths.
■
Other backup servers can also exist on the network and share the Enterprise
Tape Library 3494.
Library Request Flow for Enterprise Tape Library 3494
The IBM Automated Tape Library service sends library requests over the control
path to the IBM Library Manager. The Library Manager queues and handles
library requests from multiple backup servers in the order it receives the
requests.
Chapter 4: Enterprise Tape Library 3494 and StorageTek Options 39
Option Architecture
Mutually Exclusive Tape Volumes
In configurations where the CA ARCserve Backup server is not in a SAN, each CA
ARCserve Backup server is configured to control a mutually exclusive set of tape
volumes in the Enterprise Tape Library 3494. As a result, each CA ARCserve
Backup server manages a user-defined subset of tape volumes on the Enterprise
Tape Library 3494 that are unique to that CA ARCserve Backup server.
Mutually Exclusive Tape Volume Architecture
Each CA ARCserve Backup server has an autonomous view of the Enterprise
Tape Library 3494 that shows only the locally assigned volumes. The following
illustration shows the architecture of the CA ARCserve Backup Enterprise Option
for IBM 3494 and the communication interfaces to the Enterprise Tape Library
3494:
40 Enterprise Module Guide
Option Architecture
If multiple backup servers are sharing the same Enterprise Tape Library 3494,
you must ensure that each tape volume is assigned to only one backup server.
The tape volumes assigned to each backup server should be mutually exclusive,
which means they cannot be used or accessed by other backup servers attached
to the network.
Assigning mutually exclusive tape volumes requires careful planning. To assist
you in your planning effort, you should document the tape volume assignment
for each backup server that will share the Enterprise Tape Library 3494.
Important! If tape volumes are not mutually exclusive, or, are shared between
backup servers, you risk losing important backup data.
Note: If you are adding backup servers to an established configuration, avoid
duplication by checking the current tape volume assignments before adding the
new backup servers.
More Information:
Library Configuration Tasks (see page 62)
Chapter 4: Enterprise Tape Library 3494 and StorageTek Options 41
Option Architecture
Volume Configuration Example
The tape volume assignments determine the volume configuration for the logical
user-defined library on each CA ARCserve Backup server. In the following
example, a unique set of tape volumes defines the logical library for each CA
ARCserve Backup server:
The example shows that the Enterprise Tape Library 3494 has four tape drives
directly attached to several backup servers on the network. The unique tape
volume assignments for each CA ARCserve Backup server are:
■
Server A has six assigned tape volumes: MKT686, MKT710, MKT713,
MKT547, MKT016, and MKT 980
■
Server B has eight assigned tape volumes: MK1970, MK1963, MKT002,
MKT355, MKT774, MKT345, MKT657, and MKT114
■
Server C has four assigned tape volumes: MKT384, MKT674, MKT962, and
MKT031
Another backup server on the network that is not running CA ARCserve Backup
may have a different configuration. Other backup servers on the network can
also share the Enterprise Tape Library 3494.
42 Enterprise Module Guide
Option Architecture
Shared Tape Volumes in a SAN
In a SAN, each CA ARCserve Backup server connects directly to a SAN, which, in
turn connects to at least one tape drive in the Enterprise Tape Library 3494. In
configurations with multiple CA ARCserve Backup servers in a SAN, each backup
server is configured to control and share the same set of tape drives and tape
volumes in the Enterprise Tape Library 3494. As a result, each CA ARCserve
Backup server in the SAN shares the same user-defined subset of tape volumes
on the Enterprise Tape Library 3494.
In a SAN, the CA ARCserve Backup servers share the same logical library
configuration, the same tape volume configuration, and the same tape drive
configuration.
Note: For more information about using CA ARCserve Backup in a SAN, see
Appendix A: Storage Area Network Support in the Administration Guide.
The Enterprise Option for IBM 3494 must reside on the Primary Server in the
SAN. The following illustration shows the option architecture in a SAN and the
SAN communication interface to the Enterprise Tape Library 3494:
Chapter 4: Enterprise Tape Library 3494 and StorageTek Options 43
Option Architecture
SAN Shared Volume Configuration Example
The tape volume assignments determine the logical user-defined library shared
by all CA ARCserve Backup servers in the SAN. In the following example, a single
set of tape volumes defines the logical library for the SAN:
The example shows that the Enterprise Tape Library 3494 has three tape drives
directly attached to a SAN. The tape volume assignments are the same for each
CA ARCserve Backup server in the SAN. Another backup server on the network
that is not running CA ARCserve Backup may have a different configuration.
Tape Categories
The Enterprise Tape Library 3494 tracks the category number of each tape
volume in the library. A single category number identifies all tape volumes used
for the same purpose or application. The tape volumes imported into the
Enterprise Tape Library 3494 by the CA ARCserve Backup server are assigned to
the CA ARCserve Backup category F00F.
Insert Category
When a tape volume is first inserted into the library, either manually or
automatically at the convenience I/O station, the tape volume is assigned to the
insert category FF00. When tape volumes are imported into the CA ARCserve
Backup server, the tape volumes move from the insert category FF00 to the CA
ARCserve Backup category F00F.
44 Enterprise Module Guide
Option Architecture
Unique Application Category
Each backup server that shares the Enterprise Tape Library 3494 has its own
access defined by tape volume categories. Each backup server must use a
unique set of category numbers to identify that application. The unique
application category for CA ARCserve Backup server is F00F.
Eject Category
When a tape volume is assigned to the eject category, the tape volume is
unavailable to the CA ARCserve Backup server. The eject category is FF10.
StorageTek ACSLS
The virtual library is defined and configured by tape volume assignments for the
CA ARCserve Backup server. The virtual library configuration is defined with
mutually exclusive sets of tape volumes or with a shared set of tape volumes,
depending on whether the CA ARCserve Backup server is in a SAN.
Chapter 4: Enterprise Tape Library 3494 and StorageTek Options 45
Option Architecture
Communication Interface
Each backup server communicates directly and independently with the
Enterprise Option for StorageTek ACSLS. Although multiple backup servers may
exist on the same network, CA ARCserve Backup servers do not communicate
with other backup servers unless they are in a SAN.
Note: For more information about using CA ARCserve Backup in a SAN, see
Appendix A: Storage Area Network Support in the Administration Guide.
The communication interfaces between the StorageTek ACSLS tape library and
the CA ARCserve Backup server consist of an Ethernet LAN control path and a
(SCSI) Small Computer System Interface or fibre channel data path. The control
path and the data path are two different paths.
Control Path
The StorageTek ACSLS Library Attach software on the CA ARCserve Backup
server is connected to the StorageTek ACSLS library through an Ethernet LAN
control path. The StorageTek Library Attach software sends library requests over
the Ethernet LAN control path directly to the ACSLS Manager software on the
StorageTek ACSLS server.
Note: You can verify the network connectivity between the CA ARCserve Backup
server and the StorageTek ACSLS tape library by using the StorageTek Library
Attach software.
Data Path
Each CA ARCserve Backup server is independently connected to one or more
tape drives in the StorageTek ACSLS tape library through SCSI or fiber channel
data paths. The CA ARCserve Backup server reads and writes data on tape
volumes in the tape library managed by StorageTek ACSLS by interacting
directly with tape drives through the SCSI or fibre channel data path. In SAN
configurations, the CA ARCserve Backup servers are connected to the SAN that
is connected to the StorageTek ACSLS tape drives.
The following configurations support fibre attached tape drives:
■
The fibre attached tape drive is directly connected to the CA ARCserve
Backup server
■
The StorageTek ACSLS tape library is not shared by other CA ARCserve
Backup servers
■
In a SAN, where the CA ARCserve Backup SAN Option is installed on the
primary SAN server
46 Enterprise Module Guide
Option Architecture
Library Request Flow for StorageTek ACSLS
StorageTek ACSLS processes the requests for library operations as follows:
■
The CA ARCserve Backup server initiates requests for library operations.
■
The StorageTek Library Attached software on the CA ARCserve Backup
server transmits these requests to the ACSLS Manager on the StorageTek
ACSLS server.
■
The ACSLS Manager receives and interprets a library request, and performs
the requested operation on the StorageTek ACSLS library.
■
The ACSLS Manager also forms and returns a response to the CA ARCserve
Backup server.
The StorageTek ACSLS library request flow is shown in the following illustration:
Mutually Exclusive Tape Volumes
In configurations where the CA ARCserve Backup server is not in a SAN, each CA
ARCserve Backup server is directly connected to at least one tape drive in the
StorageTek ACSLS tape library using independent SCSI data paths.
Chapter 4: Enterprise Tape Library 3494 and StorageTek Options 47
Option Architecture
In configurations with multiple CA ARCserve Backup servers, each backup server
is configured to control a mutually exclusive set of tape volumes in the
StorageTek ACSLS tape library. Mutually exclusive tape volumes cannot be used
or accessed by other backup servers attached to the network. As a result, each
CA ARCserve Backup server manages a user-defined subset of tape volumes on
the StorageTek ACSLS tape library that are unique to that CA ARCserve Backup
server.
Mutually Exclusive Tape Volume Architecture
The following illustration shows the architecture of the Enterprise Option for
StorageTek ACSLS and the communication interfaces to the StorageTek ACSLS
tape library:
Because multiple backup servers share the StorageTek ACSLS tape library, you
must ensure that each tape volume is assigned to only one backup server. The
tape volumes assigned to each backup server must be mutually exclusive.
Important! If your CA ARCserve Backup servers are not in a SAN, tape volumes
must be mutually exclusive to each backup server or you could lose important
backup data.
Assigning mutually exclusive tape volumes requires careful planning. To assist
you in your planning effort, you should document the tape volume assignment
for each backup server that will share the StorageTek ACSLS tape library.

Appendix A: Troubleshooting
This appendix provides troubleshooting information to help you resolve issues
that you can encounter in the Enterprise Module options.
You can encounter job failures and errors while performing backup and restore
operations. To check the problems that can occur, select the Activity Log tab in
the Job Status Manager.
The Activity Log contains time-stamped events with applicable error
descriptions. Error incidents have the prefix E followed by a number (for
example, E11018).
This section contains the following topics:
Backup Process is Slow (see page 79)
Image Option: Drive Cannot be Frozen (see page 80)
Enterprise Tape Library 3494: Drives Cannot be Mapped to the Library (see page
81)
Serverless Backup Option: Drive Locking Problems (see page 81)
Backup Process is Slow
Symptom:
The backup process is very slow.
Solution:
The most common reasons and solutions for which a backup process may be
slow are:
■
Slow processor
Older computers have slow processors and may not be able to handle the
volume of data processed during the backup and restore process. This is
normal if you have an older computer with a slow processor. If your
computer is up-to-date, check your hardware performance and reboot your
computer.
■
Poor processor performance
Check your hardware performance and reboot your computer.
■
Open applications
You may have applications running that use excessive processing power.
Close all of your applications before you begin the backup and restore
process.
Appendix A: Troubleshooting 79
Image Option: Drive Cannot be Frozen
Image Option: Drive Cannot be Frozen
Symptom:
The drive cannot be frozen during a backup operation.
Note: This problem is specific to Image Option.
Solution:
If there is any activity on the drive, the CA ARCserve Backup Image Option may
not be able to freeze the drive. The following occurs if the drive cannot be frozen
during a backup operation:
■
If the drive does not freeze, and the Continue with Backup option has been
selected for the freeze fail action, the option tries to lock the drive for
exclusive access.
■
If the drive cannot be locked and you change any data, the backup data may
be inconsistent and unusable.
The drive cannot be locked for the following reasons:
■
Windows Explorer has this drive expanded. Make sure the drive is not
expanded.
■
An MS-DOS command prompt dialog is opened with this drive letter. Close
the MS-DOS command prompt dialog associated with the drive letter.
■
An application has opened a file on the drive. Make sure you close all
applications that may open a file on the drive that you are backing up.

Enterprise Tape Library 3494: Drives Cannot be Mapped to the Library
Enterprise Tape Library 3494: Drives Cannot be Mapped to
the Library
Symptom:
Drives cannot not be mapped to the library.
Note: This problem is specific to the Enterprise Option for IBM 3494.
Solution:
The reason for drives not being mapped to the library could be a registry entry,
named Device Name.
To determine if drives are mapped
1. Click Settings, Control Panel, Administrative Tools, Computer Management,
Device Manager.
2. Locate the IBM tape drives that are connected to the server from Enterprise
Tape Library 3494.
3. If the tape drives appear under Other Drives, then you must download and
install the latest device drivers for the tape drives from the IBM website.
Serverless Backup Option: Drive Locking Problems
Symptom:
Sometimes the drive lock fails.
Note: This problem is specific to the Serverless Backup Option.
Solution:
During a serverless backup or restore operation, the option attempts to lock the
drive before the backup or restore process begins. Under the following
circumstances, the lock fails and therefore the backup or restore job also fails:
■
The drive is expanded in Windows Explorer. Make sure the drive is not
expanded.
■
An MS-DOS command prompt dialog is opened with this drive letter. Close
the MS-DOS command prompt dialog associated with the drive letter.
■
An application has opened a file on the drive. Make sure you close all
applications that may open a file on the drive that you are backing up.
