Release Announcement
1.1 Notes
1.
AhsayUBS is bundled with the latest version of AhsayCBS.
2.
The maximum total number of supported processor cores has been
increased from 16 to 32. Please refer to Chapter 4.1.1 for more details.
3.
The minimum memory requirement for AhsayUBS is 2GB RAM, if
the AhsayUBS installer detects the machine has less than 2GB
RAM it will not proceed with the installation or upgrade.
4.
For machines installed with 64bit CPU, AhsayUBS will now only run in 64
bit mode. The option to switch to 32bit mode has been removed from
the AhsayUBS "System Management Console (64bit)" menu.
5.
For machines installed with 32bit CPU. The option to switch to 64bit
mode has been removed from the AhsayUBS "System Management
Console (32bit)" menu.
6.
AhsayUBS is not supported running as a guest O/S under Microsoft
Hyper-V as FreeBSD 8.3-stable release is not a supported Hyper-V guest
O/S.
7.
The upgrade of AhsayUBS installations running on both the UFS storage
model and the previous ZFS storage model.
8.
Supports both iSCSI and Additional Storage features.
www.ahsay.com
1
Ahsay Universal Backup System Administrator’s Guide
1.2 The UFS storage model
For backwards compatibility with older AhsayUBS versions, the UFS storage
model is also supported. After upgrading, the 'geom_concat.ko',
'geom_stripe.ko', and 'geom_raid5.ko' module will be loaded by the FreeBSD
to support the UFS storage model. To check if these kernel modules have
been loaded correctly you can run the “kldstat” command, which will return
the following output.
The 'Master Storage Device' on AhsayUBS is preserved in UFS format which is
mounted on '/ubs/mnt/eslsfw' upon system boot time. The following example
shows a UFS filesystem mount as '/ubs/mnt/eslsfw'.
The Optional Labelled Device in the old AhsayUBS will migrated in this
version of AhsayUBS which is one of the storage types called “Optional
Storage” inside the “Additional Storage”. Volume status and UFS filesystem
integrity checking (fsck) are also available in this AhsayUBS version. For
details, please refer to the section [Storage].
www.ahsay.com
2
Ahsay Universal Backup System Administrator’s Guide
1.3 The ZFS storage model
AhsayUBS v7 is implemented with ZFS v5 and ZPOOL v28. The existing
ZPOOL(s) will not be upgraded and only newly created ZPOOL will be applied
with the ZIL. As the ZFS storage model is based on a GMIRROR and ZFS
design, therefore the 'geom_mirror.ko', 'opensolaris.ko', and 'zfs.ko' kernel
modules will be loaded by the FreeBSD. The GEOM kernel modules used
previously for UFS support 'geom_concat.ko', 'geom_stripe.ko', and
'geom_raid5.ko' will also be loaded. To check if these kernel modules have
been loaded correctly you can run the “kldstat” command, which will return
the following output.
The 'Master Storage Device' on AhsayUBS is configured as a ZPOOL with the
following pool name 'eslsfwx{UID}' format. The ZFS pool will be mounted on
'/ubs/mnt/eslsfw' upon system boot time. The following example shows a
zpool volume of size 191GB “eslsfwx839830C2” mount as '/ubs/mnt/eslsfw'
For volume status and ZFS filesystem integrity checking, please refer to the
section [Storage] for details
The other “esgpbt”, “esosfw”, and “esfmfw” System Firmware Devices are
still mounted from the /etc/fstab file.
www.ahsay.com
3
Ahsay Universal Backup System Administrator’s Guide
The ZFS storage model is used for the following AhsayCBS locations:
1.
%USER_HOME%
2.
%SYSTEM_HOME%
3.
%POLICY_HOME%
4.
%CONF_HOME%
5.
%WEBAPPS_HOME%
6.
%RECEIVER_HOME%
The other “System Firmware Devices” such as “esgpbt”, “esosfw”, and
“esfmfw” will remain unchanged as GEOM MIRROR based UFS volumes. The
GEOM device names are in the following formats:
1.
GPT Boot - {UID}xesgpbt
2.
Operating System Framework - {UID}xesosfw
3.
Firmware Module Framework - {UID}xesfmfw
Note:
For production AhsayUBS servers configured with ZFS volume(s). It is
strongly recommended to install at least 4 GB RAM, as ZFS volumes require
relatively large amount of memory to run. The amount of memory required is
dependent on the size of the ZFS volume and the amount of I/O activity.
www.ahsay.com
4
Ahsay Universal Backup System Administrator’s Guide
1.4 ZFS Integrity Checking
In order to safeguard the data integrity of the files on the ZFS volume, a
weekly “zpool scrub” (zpool volume data integrity check) is performed
starting at 00:00 every Sunday morning. To verify the checksums of all the
data in the specified ZFS pools are correct. The scheduled started time of the
“zpool scrub” is currently not user configurable and it cannot be disabled in
this version of AhsayUBS. Once the “zpool scrub” job has started it is not
possible to stop it.
To check the status of the “zpool scrub”, you can use the “zpool status”
command which will return the following output. For the following example
the “zpool scrub” has checked 56.33% of the pool: eslsfwx839830C2
If an additional data integrity check is required in between the scheduled
weekly checks. It is possible to initiate a manual “zpool scrub” using the
“zpool scrub {% POOL_NAME%}” command. As with the weekly “zpool
scrub”, the AhsayCBS service and backup/restore operations can continue to
run as normal.
Note:
There may be some performance overhead associated with a “zpool
scrub”, i.e. CPU utilization, memory, and increased I/O activity. The
performance overhead is proportional to the amount of data on the
ZFS volume.
www.ahsay.com
5
Ahsay Universal Backup System Administrator’s Guide
1.5 FreeBSD and ZFS Implementation
The ZFS version 5 and ZPOOL v28 on AhsayUBS has undergone an extended
period of intensive performance and load testing, which has consistently
delivered superior performance and data integrity results in comparison to
UFS.
1.6 Storage Model Migration
For existing AhsayUBS customers who wish to migrate from UFS to ZFS
storage model, only a manual migration method is available.
The migration process will involve:
1.
Copying the existing user data from AhsayUBS server to another
storage device.
2.
Use the latest AhsayUBS installer to install a new version of AhsayUBS
on the existing machine, which will overwrite all existing data.
3.
Copy the user data from the storage device back to the AhsayUBS
server.
www.ahsay.com

Ahsay Universal Backup System Administrator’s Guide
Overview
The process to setup Ahsay Universal Backup System (AhsayUBS) firmware
on a machine is divided into 4 stages:
1.
Installer Image Development
Deploys Ahsay Universal Backup System Installer image on removable
USB storage device.
2.
Firmware Installation/Upgrade
Install / upgrade Ahsay Universal Backup System Firmware into a
machine.
3.
Ahsay Universal Backup System Configuration
Configures the Ahsay Universal Backup System Firmware.
4.
Backup Server Configuration
Configures the Backup Server and Replication Server (AhsayCBS)
There are different software/hardware requirements for each stage. Please
ensure that all the requirements are met before deploying the Ahsay™
Universal Backup System to the machine. For information on the
software/hardware requirements, please refer to Chapter 4 System
Requirements of this document.
2.1 Ahsay Universal Backup System Firmware
AhsayUBS Firmware is a customized FreeNAS firmware with AhsayCBS
bundled and it is optimized to run AhsayCBS. Apart from AhsayCBS, it also
contains some basic features that system administrator require, e.g. SSH and
system monitor.
2.1.1 AhsayUBS Storage Concepts
The AhsayUBS installer will automatically detect all available local hard disk(s)
during the installation progress. The selected hard disk(s) will be partitioned
to form “Systsem Storage”. Several RAID devices will be created on the
“System Storage”:
1.
GPT Boot (GPBT)
2.
Operating System Framework (OSFW)
3.
Firmware Module Framework (FMFW)
www.ahsay.com
7
Ahsay Universal Backup System Administrator’s Guide
4.
Logical Storage Framework (LSFW)
The GPBT, OSFW and FMFW volume are configured as RAID1 in UFS file
system to form the core system. The LSFW RAID device:
Supports JBOD, RAID0, RAID1 and RAID5 in UFS format for old version
of AhsayUBS.
Supports RAID0, RAID1 and RAIDZ in ZFS format for the new version of
AhsayUBS (The raid type depends on the number of hard disks installed
and selected during AhsayUBS installation, for RAID0 the minimum
number of disks is required is 1, for RAID1 and RAIDZ the minimum
number of disks required is 2).
These volumes are named “System Storage”. The OSFW, FMFW devices will
be created on the Unix File System (UFS). The firmware configuration files
will be stored on OSFW and the AhsayCBS configuration files and backup data
will be stored on LSFW.
If the LSFW file system runs out of disk space, extra storage can be added to
the system by either:
1.
Adding a new block device to the system hardware.
2.
Creating an iSCSI connection to a remote storage server.
The added block devices will be partitioned and formatted to form "Modular
Storage (ZFS + ZIL)". The previously suported additional storage 'Modular
Storage (ZFS)', 'Expandable Storage (ZFS)' and 'Optional Storage (UFS)' will
also be listed in the summary page. However, only removal of those
additional storage is allowed. Expandable Storage volumes (ZFS) can no
longer be created.
There are three types of Additional Storage:
1.
Modular Storage (ZFS / ZFS+ZIL)
can be created by one or more local block device to form a volume
either in RAID0, RAID1 or RAIDZ (is dependent on the number of hard
disks used to form the volume). Since this AhsayUBS version, the
underlying ZPOOL will be added with a ZIL layer.
2.
Expandable Storage (ZFS)
created in the former AhsayUBS versions with a hardware raid volume
or an iSCSI initiator session connected to this AhsayUBS machine. A
RAID0 ZFS filesystem will be formed for each of the Expandable Storage.
It is for supporting the old migrated AhsayUBS only and cannot be
created in this version of AhsayUBS.
www.ahsay.com
8
Ahsay Universal Backup System Administrator’s Guide
3.
Optional Storage (UFS)
called “Optional Labelled Device” on earlier AhsayUBS versions. It is for
supporting the older migrated AhsayUBS installations only and cannot
be created in this version of AhsayUBS.
By configuring the AhsayCBS, the “Additional Storage” can be used as
additional storage for storing server configuration files and backup data.
Note:
Minimum size 100GB is required for the AhsayUBS Backup System block
devices (i.e. System Storage and Additional Storage). Otherwise, the added
block device will not be allowed for fail disk replacement and additional
storage.
The AhsayUBS WebAdmin page, under [Storage] > [Summary] will show the
overview of the volumes created on AhsayUBS.
www.ahsay.com

Ahsay Universal Backup System Administrator’s Guide
Important Notice
The Ahsay™ Universal Backup System provides console access to the
“System Management Console” by connecting a keyboard and a VGA monitor
to the machine. To prevent unauthorized access to the AhsayUBS System
Management Console, it is advised to change the AhsayUBS administrator
password.

Ahsay Universal Backup System Administrator’s Guide
System Requirements
This chapter describes the system requirements for the Installer Image
Deployment, Backup System firmware Installation/ Upgrade, Backup System
and Backup Server Configuration.
4.1 Backup System Requirements
The selected machine must meet the following requirements:
CPU: At least 1 CPU that is FreeBSD i386 / amd64 compatible.
Memory Size: 2 GB minimum
Disk Storage Space: 100GB per disk minimum
Network interface card (NIC): At least 1 NIC that is FreeBSD
i386/amd64 compatible.
If an AhsayUBS server motherboard supports Unified Extensible Firmware
Interface (UEFI) standard. The boot mode must set to BIOS boot manager
and the AhsayUBS installed hard disk specified as the first the boot device.
If the AhsayUBS installer detects that the machine is installed with
less then 2GB RAM the installation or upgrade process will be aborted.
AhsayUBS is not supported running as a guest O/S under Microsoft
Hyper-V, as FreeBSD 8.2-stable release is not a supported Hyper-V
guest O/S.
For production AhsayUBS servers configured with ZFS volume(s). It is
strongly recommended to:
1.
Install AhsayUBS on a 64bit machine.
2.
Install at least 4 GB RAM, as ZFS volumes require relatively large
amount of memory to run. The amount of memory required is
dependent on the size of the ZFS volume and the amount of I/O activity.
For the list of FreeBSD i386/amd64 compatible processors, please refer to
Appendix A.
WARNING:
For 32bit production AhsayUBS servers configured with ZFS volumes. Due to
FreeBSD kernel memory limitations on 32bit CPU’s, combined with the
relatively high memory usage requirements of ZFS volumes. AhsayUBS
servers hosting large amounts of data can become unstable and even crash,
which could result in data corruption on AhsayCBS.
www.ahsay.com
11
Ahsay Universal Backup System Administrator’s Guide
4.1.1 AhsayUBS Processor Configuration
AhsayUBS supports up to a maximum of 32 virtual processors for both
i386/amd64 compatible CPU’s.
In order to comply with the maximum supported virtual processors limit on
FreeBSD, the system administrator should verify the number of virtual
processors enabled on the AhsayUBS machine and apply the correct
processor setup on the machines BIOS before proceeding with AhsayUBS
installation or upgrade.
The maximum number of virtual processors is calculated as:
(No. of sockets) * (No. of cores per processor) * (Hyper Threading).
The following are examples of processor configurations.
Supported Processor Configurations
1.
One Socket, Dual-Core Intel CPU, Hyper Threading Enabled
(1) * (2) * (2) = 4 virtual processors
2.
Two Sockets, 6-Core Intel CPU, Hyper Threading Enabled
(2) * (6) * (2) = 24 virtual processors
3.
Two Sockets, 8-Core Intel CPU, Hyper Threading Enabled
(2) * (8) * (2) = 32 virtual processors
4.
Four Sockets, 4-Core Intel CPU, Hyper Threading Enabled
(4) * (4) * (2) = 32 virtual processors
Non-supported Processor Configurations and workarounds
1.
Two Sockets, 12-Core AMD CPU, Hyper Threading Enabled
(2) * (12) * (2) = 48 virtual processors
It is recommended the number of cores per CPU be set at 8 on the
machine BIOS:
(2) * (8) * (2) = 32 virtual processors
2.
Four Sockets, 8-Core Intel CPU, Hyper Threading Enabled
www.ahsay.com
12
Ahsay Universal Backup System Administrator’s Guide
(4) * (8) * (2) = 64 virtual processors
It is recommended that Hyper Threading is disabled on both CPU’s on
the machine BIOS:
(4) * (8) * (1) = 32 virtual processors
3.
Four Sockets, 10-Core Intel CPU, Hyper Threading Enabled
(4) * (10) * (2) = 80 virtual processors
It is recommended that Hyper Threading is disabled on both CPU’s and
the number of cores per CPU be set at 8 on the machine BIOS:
(4) * (8) * (1) = 32 virtual processors
WARNING:
If AhsayUBS is installed on a machine where the number of virtual processors
configured exceeds the maximum supported value of 32. This will cause
FreeBSD to become unstable and crash, which could result in data corruption
on AhsayCBS.
4.2 Installer Media Requirements
AhsayUBS installer is available in img format and ISO format. For img format,
you can deploy it on the USB flash drive (minimum 1GB), while the ISO
format is used for VMware installation only.
4.3 Installer Deployment
Please ensure the following requirements are met before deploying Ahsay™
Universal Backup System image to a USB flash drive.
1.
The USB flash drive is listed in our supported hardware list. Please refer
to Chapter 4.2 for more information on the supported USB flash drives.
2.
The USB flash drive should meet the minimum 1GB storage size
requirements.
3.
Previous data stored on the USB flash drive should be backed up
properly. Once the deployment process begins, all data on the
USB flash drive will be OVERWRITTEN.
4.
To avoid selecting the incorrect drive for deployment, it is advised to
remove all other USB storage devices such as USB portable hard disk
and other USB flash drive.

The installation process will destroy all the data in the local block
devices installed in the machine. To protect the data in some of the local
block devices, it is recommended to remove them before the installation
of AhsayUBS Firmware.
The upgrade process requires the existing RAID storage configuration to
be healthy. The upgrade process will not be able to continue on system
configuration with one or more DEGRADED RAID devices.
4.4 AhsayUBS and Backup Server Configuration
The following requirements must be met before setting up the network in the
AhsayUBS console:
Configure the firewall of your computer to enable traffic for the following
ports:

8.2.1.7 SNMP
SNMP (Simple Network Management Protocol) is a protocol defined for
managing the computer devices such as servers, workstations and desktop
etc. through IP networks. The software which monitors and configures the
devices in the network is called NMS (Network Management Server). When a
SNMP agent daemon is enabled in the AhsayUBS, the AhsayUBS
administrator may monitor the system status such as performance of CPU,
memory, disk and network with a proper setup NMS from a remote machine.
The AhsayUBS has been bundled with the FreeBSD SNMP agent ‘bsnmpd’
daemon which supports up to SNMP v2c standard. The functions of this
daemon include:
report OID object value upon SNMP query from the NMS via UDP port
‘161’.
send traps to the NMS upon defined events in the AhsayUBS.
It is better for the AhsayUBS administrator to install a ‘bsnmpd’ supported
NMS for communication.
Here are the SNMP modules bundled with the ‘bsnmpd’ daemon:
MIB-II
Implements parts of the internet standard MIB-II.
Netgraph
Enable remote access to FreeBSD Netgraph subsystem.
Host resources
Implements the HOST-RESOURCES-MIB as standardized in RFC 2790.
UCD-SNMP-MIB
Retrieve system performance information and device detail.
www.ahsay.com
72
Ahsay Universal Backup System Administrator’s Guide
The SNMP daemon will be started once the settings are saved in the page
[System] > [Settings] > [SNMP]. SNMP triggered event can be found in the
AhsayUBS system log at page [Information] > [System Logs].
SNMP Settings
AhsayUBS Administrator can configure the SNMP settings and check the
SNMP daemon status in the page [System] > [Settings] > [SNMP].
Please enter / select the fields below to configure the ‘bsnmpd’ daemon:
Enable ‘checkbox’: Enable / Disable the ‘bsnmpd’ daemon.
Status: ‘bsnmpd’ daemon current status [ Running / Cannot be enabled
/ Stopped ].
Location: The physical location of the AhsayUBS machine.
Contact: The textual identification of the contact person for this
AhsayUBS machine, together with information on how to contact this
person.
Community: The community string acts as a password to communicate
with the NMS. Default is ‘public’. It is better to set a value different from
the default one or any dictionary words in order to prevent brute force
attack. Only read-only community is supported by AhsayUBS.
Traps: Enable traps (notifications) send from the SNMP daemon.
www.ahsay.com
73
Ahsay Universal Backup System Administrator’s Guide
Trap host [shown when ‘Traps’ is enabled]: Enter hostname that the
trap will be sent to.
Trap port [shown when ‘Traps’ is enabled]: The listening port of the trap
host for receiving traps. Default is UDP port ‘162’.
Trap string [shown when ‘Traps’ is enabled]: The passcode for the trap.
It should match the one defined in the NMS.
Please click [Save and Restart] button to save the above settings and update
the status of the ‘bsnmpd’ daemon in the AhsayUBS.
Import MIB files to the NMS which are supported by this ‘bsnmpd’
daemon:

WebAdmin page. The zip file contains all the MIB files which are supported by
the ‘bsnmpd’ daemon. Please extract the files and import them to the NMS /
MIB browser.
Browse the OID in the MIB browser to get / monitor the information:
After importing the MIB files into the MIB browser, the system information
can be browsed in the MIB tree. Administrators may configure the MIB
browser to monitor AhsayUBS by selective OID. Please refer to the Appendix
for the OID list and the OIDs’ description.

default settings is leave to n, default is interface specific (i.e. blank).
The MTU is used to limit the size of packets that are transmitted on an
interface. Not all interfaces support setting the MTU, and some
interfaces have range restrictions.
Device polling: Device polling is a technique that lets the system
periodically poll network devices for new data instead of relying on
interrupts. This can reduce CPU load and therefore increase throughput,
at the expense of a slightly higher forwarding delay (the devices are
polled 1000 times per second). Not all NICs support polling.
Type: Select the speed of network from the drop down list.
Extra options: You can enter extra options for the FreeBSD command
“ifconfig” here. For more information of this command, please refer to

the volume are missing though the volume can still be used. The
volume can become healthy again with a rebuild after replacing the
missing providers. For details, please refer to the [Troubleshooting]
section.
Rebuilding
This state will occur after the provider is replaced in the volume. After
rebuilding completed, the status will become healthy again. The
rebuilding state will not affect the read or write operation of the
volume.
Critical
The volume is not available. It is better to suspend all I/O activity
before the volume has undergone further damage.
Missing
The volume is missing. It cannot be accessed by the AhsayUBS. It
may be caused by:
 The volume is exported.
 The local storage is disconnected.
For details, please refer to the [Troubleshooting] section.
Disconnected
The corresponding remote disk’s connection is lost. Please bring the
remote storage host up (e.g. iSCSI initiator) to reconnect the remote
disk. In order to prevent any data access to the remote storage, the

8.4.4.2 Additional Storage(s) in Disconnected State
The additional storage DISCONNECTED state will only appear in the volume
which is created on a remote disk (i.e. iSCSI initiator session). This states
that the addition storage corresponding remote disk provider (i.e. iSCSI
initiator session) is disconnected from the AhsayUBS.
In order to identify disconnected additional storage, an additional schedule
job has been added to AhasyUBS. When any additional storage has been
detected in disconnected state, the following actions will be taken in order to
prevent further loss of data:
Service stop and prohibit the service start of the following services:
AhsayCBS
Share OBSR
The enabled additional storage volumes will remain mounted. The
system will wait for iSCSI initiator reconnection. In case the iSCSI
initiator exits due to session timeout, AhsayUBS administrator may
create another iSCSI initiator sessions by the ‘Retry’ button at page
“Storage > iSCSI”.
Email will be sent to AhsayUBS administrator (The ‘To email’ defined in
the ‘General email setting’).
At this stage,
the corresponding remote disk’s (i.e. the iSCSI initiator session)
network connection to this UBS machine is lost.
though the corresponding additional storage is still mounted, the data in
this volume cannot be accessed nor written anything to the storage.
To fix the problem, login the AhsayUBS WebAdmin
www.ahsay.com
120
Ahsay Universal Backup System Administrator’s Guide
Alert dialog contains the disconnected additional storage and their
corresponding iSCSI initiator information will be shown after AhsayUBS
WebAdmin login.
The lost of iSCSI connection may result from network connectivity issue.
Try to use “Network > Ping / Traceroute” tool to test if the iSCSI target
host is reachable. After resolving the network issue, the iSCSI target
host will be reconnected with AhsayUBS machine and the data in the
additional storage can be accessed again.
After resolving the additional storage disconnection issue, service start
will be allowed for the following services. Please refer to the section
[Backup Server] for details.

8.4.5 Additional User Storage Migration
8.4.5.1 Introduction
AhsayUBS additional user storage migration is performed using a UNIX shell
script. The migration process only supports additional user storage volumes,
the system storage (firmware) volume, i.e. FreeBSD and AhsayCBS binaries
are not supported. After a successful migration, the data on the file system
can be used by the AhsayCBS service on the new AhsayUBS server.
Supported Hard Disk Interfaces:
Local: IDE, SCSI, SATA, Hardware RAID
Foreign: iSCSI
Supported Additional Storage Types:
The storage migration script only supports the migration of additional storage
with only one provider (single hard disk). The storage volume to be migrated
must in a healthy state. The support storage types include:
Optional Storage (GPT Partition 6 with UFS)
Expandable Storage (No Partition with ZPOOL on entire disk)
Modular Storage with CLOG only (GPT Partition 7 with ZFS)
Modular Storage with CLOG & SLOG (GPT Partition 11 / 13 with ZFS)
www.ahsay.com
121
Ahsay Universal Backup System Administrator’s Guide
WARNING:
1.
AhsayUBS system storage (esosfw/eslsfw) is NOT supported by the
storage migration shell script.
2.
After volume migration the original storage label in the migrated storage
volume will be updated. The previous AhsayUBS installation will no
longer be able to use the migrated storage volume.
3.
Since the profile.ini file (/ubs/conf/profile.ini) will be updated by this
shell script. DO NOT perform any add or remove storage operations via
the AhsayUBS webadmin console when the volume is migration is in
progress.
8.4.5.2 Storage Migration Procedure
Assumptions
1.
The volume to be migrated is in a healthy state.
2.

8.5.2 Tape Utility
8.5.2.1 Introduction
The AhsayUBS administrator may backup selected user accounts to tape
cartridge while the backup server remains online. The AhsayCBS user account
data can be restored to the AhsayUBS server either to the original or an
alternate location. The tape backup/restore operation is managed from the
AhsayUBS webadmin console.
‘User Home’ setting in the Backup Server
For AhsayCBS that stores all user accounts locally under the ‘User Home’
directories. When a new user account is being created, AhsayCBS will create
a directory with the user’s login name under the assigned ‘User Home’ path.
The created user directory is used for storing user configuration and backup
files. The list of user names can also be found from the AhsayCBS WebAdmin.
Tape Device and Tape Standards
FreeBSD provides full support for SCSI-I, SCSI-II and SCSI-III tape drives.
As AhsayUBS is built on top of the FreeBSD operating system, SCSI tape
drives are therefore supported. The ‘sa – SCSI Sequential Access device
drive’ will be used for accessing the tape device.
Note: Tape libraries and tape changers are NOT supported by AhsayUBS.
The following tape drive standards are supported by FreeBSD. Each tape
standard has its own maximum data capacity and transfer rate. For each
hardware type and supported tape standard, the cost of the tape drive and
tape cartridge varies.

Ahsay Universal Backup System Administrator’s Guide
2.
DLT - Digital Linear Tape (halted development since 2007)
3.
LTO - Linear Tape Open
Before purchasing a tape drive, please consult your hardware vendor to
confirm compatibility of the device with the FreeBSD operating system.
The following factors should also be considered:
1.
Compatible hardware interfaces with the AhsayUBS
connecting tape drive.
2.
Tape cartridge capacity for storing user data.
3.
Tape transfer rate.
machine for
Note: Tape backup/restore on AhsayUBS has been developed and tested
using a DELL PowerVault LTO-4 tape drive, connected to a DELL 6GB HBA
SAS controller using 800GB LTO-4 tape cartridges.
Tape Backup/Restore Process via the AhsayUBS WebAdmin
An AhsayUBS administrator may backup/restore user home data to/from tape
cartridges via the AhsayUBS webadmin console [Backup Server] > [Tape
Utility] menu option.
Before using the [Tape Utility] option, the tape device must be:
1.
Connected with the AhsayUBS server.
2.
The tape device must be powered on.
www.ahsay.com
128
Ahsay Universal Backup System Administrator’s Guide
3.
AhsayUBS must be able to detect the tape hardware. The identified tape
device will be shown in the [Backup Server] > [Tape Utility] > [Tape
Device] (As shown in the following example).
In most cases, a single tape cartridge will not be sufficient to store all the
data on a user home volume. During a backup operation if the current tape
cartridge is full, AhsayUBS will prompt for a new tape cartridge to be inserted
into the tape drive. For tape restore operations if the data spans more than
one tape cartridge, AhsayUBS will prompt for the insertion of the next tape
cartridge.
If a tape device is not supported or no tape drive is installed on the
AhsayUBS machine, the AhsayUBS webadmin [Backup Server] > [Tape Utility]
menu option will be disabled, the following message “The system cannot
find any supported tape device.” (As shown in the following example).
Notes:
1.
Tape cartridges must be managed, handled, and stored properly. Proper
care by trained staff is important to prevent inadvertent errors and
media damage.
2.
Only ONE tape backup/restore process can be started at a time.
www.ahsay.com
129
Ahsay Universal Backup System Administrator’s Guide
3.
Only ONE tape cartridge can be used for tape backup/restore process at
a time.Therefore, manual tape cartridge replacement is required when
the current tape cartridge full.
4.
Only ONE AhsayCBS ‘User Home’ path can be selected for backup at a
time.
5.
Only CONSECUTIVE tape cartridge can be used for restore.
6.
Any corrupted or damaged intermediate tape cartridge(s) will result in
the failure of the entire tape restore process.
7.
The AhsayCBS service MUST BE stopped prior to a tape restore, if
restoring to an existing AhsayCBS ‘User Home’ path.

Method 1: Serial Number
The “Serial Number” is the unique identifier for a block device. Thus, the
block device can be found physically in the machine by its serial number.
Here are the steps to look for the serial number in the AhsayUBS WebAdmin:
1.
In the page [Storage ] > [Summary], click on the block device icon ‘ ’
that looking for.The page then will be redirected to [Storage] >
[Summary] > [Block Device Information].
2.
If the “Serial Number” can be retrieved by the block device, the row
“Serial Number” will exist in the table.
Method 2: Device name
If a block device is connected to a specific controller e.g. 'ad' for ATA or 'da'
for SCSI. The connector will be named and ordered starting from 0, e.g. ad0,
ad1, da0, da1 … etc. Therefore, the block device can be identified according
to the controller name and the connector number.
To look for the device name, please follow the steps below:
1.
In the page [ Storage ] > [ Summary ], click on the block device icon
‘ ’ that looking for. The page then will be redirected to [ Storage ] >
[ Summary ] > [ Block Device Information ].
2.
The “Device Name” exists in the information table.

www.ahsay.com
169
Ahsay Universal Backup System Administrator’s Guide
‘below’ the network layer in the protocol stack.
For interfaces which do not have such an address (e.g.,
a serial line), this object should contain an octet string of
zero length.

combination of the ‘ssCpuRawWait(54)’ and
‘ssCpuRawKernel(55)’ counters, so care must be taken
when summing the overall raw counters.
ssCpuRawUser
The number of ‘ticks’ spent processing user-level code
over the last minute.
ssCpuRawIdle
The number of ‘ticks’ spent idle over the last minute.
www.ahsay.com

MIB Browser allows administrators to load MIB definition files and connects to
SNMP enabled network devices and applications. Some MIB browsers provide
both text view and table view for the retrieved MIB values. In the following,
we are going to demonstrate with the ‘iReasoning MIB Browser Personal
Edition’.
(http://ireasoning.com/downloadmibbrowserfree.php)
1.
The MIB Browser GUI includes the following views:
Address and Advanced (menu bar, for SNMP agent connection
configuration)
MIB Tree (top left panel, presenting the supported MIB entities)
MIB Description (bottom left panel, presenting the MIB entity detail)
Result Table (top right panel, presenting the OID query result)
www.ahsay.com
172
Ahsay Universal Backup System Administrator’s Guide
2.
Additional MIB definition files can be loaded to the MIB Browser.
Download and extract the MIB archive from UBS [ System -> Settings > SNMP ].
Click on ‘File -> Load MIBs’ to load the following MIB definition files:
BEGEMOT-HOSTRES-MIB.txt
BEGEMOT-IP-MIB.txt
BEGEMOT-MIB.txt
BEGEMOT-MIB2-MIB.txt
BEGEMOT-NETGRAPH.txt
BEGEMOT-SNMPD.txt
FOKUS-MIB.txt

Ahsay Universal Backup System Administrator’s Guide
3.
SNMP ‘Get’ and ‘Walk’ operation
By selecting specific OID entities, the SNMP ‘Get’ operation will retrieve
the selected OID values. The OID entities will be mapped with the
corresponding name defined in the MIB files. For example, we may
retrieve
the
all
entity
values
under
the
OID
‘iso.org.dod.internet.mgmt.mib-2.system’ via the MIB Browser.
www.ahsay.com
174
Ahsay Universal Backup System Administrator’s Guide
On the other hand, the MIB Browser may walk through the entire MIB
Tree by the SNMP ‘Walk’ operation. All OID entities will be retrieved
from the SNMP agent. If the corresponding MIB definition file is not
found, the retrieved OID will be displayed in numeric format.
4.
MIB Browser Table View
Some OID may exist as customized entry type. Multiple instances of
entity value may exist under certain OID. For example, a system may
contain multiple disks that each disk could be indexed by a unique index
value. In such case, the MIB Browser may provide the ‘Table View’ that
all supported entity values can be presented in table format.
From OID ‘iso.org.dod.internet.private.ucdavis.dskTable.dskEntry’, we
may retrieve the system disk detail in table view with the corresponding
‘dskPath’, ‘dskDevice’, ‘dskTotal’, ‘dskUsed’ and ‘dskPercent’ entity
values.
