iSCSI Disk Backups

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

Using Backup Exec for 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:
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
(such as, 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:
VALUE NAME
ID
Name
Version
5. Close
The SnapServer VSS Provider should now be available to Backup Exec to use for VSS-based
backups.
