Backup of iSCSI Disks 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: VALUE NAME VALUE DATA Id Name {759c7754-6994-46c9-9cf9-c34ac63a0689} SnapServer VSS Hardware Provider Version 5.2 5) Close regedit. The Snap VSS Provider should now be available to Backup Exec to use for VSSbased backups. 166 SnapServer Administrator Guide
