Backup of iSCSI Disks
166 SnapServer Administrator Guide
Backup of iSCSI Disks
iSCSI disks can be backed up from iSCSI clients using any standard backup
application on the client operating system. These backups run independently of the
SnapServer since the client backs up the contents of the iSCSI disk as if the iSCSI
disk were a local hard disk.
Windows clients can make backups of VSS-based snapshots of iSCSI disks using
VSS-compatible backup applications. See “Backing up an iSCSI Disk using VSS
Snapshots” on page 141 for instructions.
Using Backup Exec to Take VSS-based Snapshots of SnapServer iSCSI
Disks
To configure Backup Exec to take native VSS snapshots of SnapServer iSCSI disks
using Backup Exec’s Advanced Open File or Advanced Disk-Based Backup feature, you
must first add a Windows registry entry to the systems running the Backup Exec
Server and all of the Backup Exec agents backing up iSCSI disks.
After the Backup Exec Server or agent has been installed, modify the registry to add
the SnapServer as a Backup Exec VSS provider:
1
Run the following command:
regedit
2
Navigate to the following key:
[HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Backup Exec For
Windows\Backup Exec\Engine\Misc\VSSProviders]
3
Underneath VSSProviders are other keys numbered sequentially from 0 to some
number. Create a new key in VSSProviders named after the highest key value
plus 1 (i.e., if the highest key value is 9 , create a new key value 10 ). For example:
[HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Backup Exec For
Windows\Backup Exec\Engine\Misc\VSSProviders]\10
4
Inside the new key, create three string values:
5) Close
regedit
.
The Snap VSS Provider should now be available to Backup Exec to use for VSS-
based backups.
