How to Perform Backup of Cluster Shared Volume

Arcserve UDP supports the backup of Cluster Shared Volume (CSV) from v6.5 Update 4. The CSV volumes are created upon Storage Space and are transparent to Arcserve UDPAgent (Windows). CSV is always considered for full backup at volume level, irrespective of the backup job type ( full or incremental). The CSV backup protects the data of all popular file systems such as NTFS, NTFS Dedupe, ReFS and CSVFS.

You can create an agent-based plan or update an existing agent-based plan from Arcserve UDP Console to perform backup of specified CSV.

Follow these steps:

1. Select Cluster Shared Volume in Agent Machine. For more information, see Modify Agent Machine Settings to Backup CSV Volume.
2. Note: You can also run the backup job from Windows Agent machine. For more information, see How to Perform Backup from Windows Agent Machine.
2. To perform backup from Arcserve UDP Console, navigate to the Resources tab.
3. From the left pane, navigate to Plans, and click All Plans.
4. On the center pane, click Add a Plan and specify a plan name.
5. From the Task Type drop-down list, select Backup: Agent-Based Windows.
6. From the Source tab of Plan, select the checkbox of Back up all volumes as Protection Type.
7. Specify the Destination, Schedule, and Advanced details. For more information, see How to Create a Windows Backup Plan.
8. Now, after saving the plan when you run the backup job, the specified CSV volume is backed up for Windows agent.
8. Verify the status of backed up jobs. For more information, see Verify the Backup.
9. Notes:
• The activity log of the owner node displays the progress of the backup job and logs the success message upon completion of the backup. The activity log of the member node (which is not the owner) displays a warning message as below, but the backup status shows as successful.
• Warning: Failed to fetch physical location of Cluster Shared Volume[C:\ClusterStorage\Volume1]. This volume will be excluded from the backup.
• If you want to exclude the CSV volume during the backup, perform the following steps:
1. On the UDP Agent node, open the Registry to the following path:
2. HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine\AFBackupDll
2. Create a DWORD as ‘BackupCSV’.
3. Set the value to 0.
4. The CSV volume is now excluded during the backup.
