Use Hardware Snapshot for VMware Agentless Backup

Follow these steps:

1. Verify if the following prerequisites are met:

For NetApp Snapshot

• Arcserve UDP supports NetApp iSCSI//FC LUNs and NetApp NFS Volume exports that are configured as Data stores. iSCSI, FC, and NFS must meet certain conditions to use the hardware snapshot.

Considerations for NetApp iSCSI/FC Support for VMware

Considerations for NFS Support for VMware

• To create a hardware snapshot for VMware, add the storage array to the Console. For more information on adding a storage array, see Add a Storage Array.
• To use a hardware snapshot, Flexclone license is recommended for NetApp storage arrays running with data ONTAP, operating in the 7-Mode and Cluster mode.

Note: For more information on configuring NetApp, refer the NetApp documentation or contact the NetApp Support team.

HPE 3PAR hardware snapshot:

• To support the VMware VM hardware snapshot, HP RMC must manage the HPE 3PAR storage array.
• The storage array needs to have Virtual copy license.
• Supported protocols for VMware hardware snapshot: FC and iSCSI
• To create a hardware snapshot for VMware, add the storage array to the Console. For more information on adding a storage array, see Add a Storage Array.

Nimble hardware snapshot:

• Supported protocols for VMware hardware snapshot: FC and iSCSI
• To create a hardware snapshot for VMware, add the storage array to the Console. For more information on adding a storage array, see Add a Storage Array
• Considerations for Nimble Storage When CHAP Authentication is enabled
2. Log on to the Console and create a plan for backup.
3. Note: For more information on creating an agentless backup plan, see How to Create a Host-based Agentless Backup Plan.
3. Verify that you have selected the Use hardware snapshot wherever possible option in the Advanced tab.
4. Note: To run backup only from hardware snapshot (not software snapshot), Arcserve UDP provides the following registry key: FallbackToSWSnapshot =0(dword)
5. You can apply this registry key for a specific node as well as all nodes.
• To apply for a specific node create the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine\AFBackupDll\(Nodeid)

Note: The (Nodeid) is created only after one backup.

• To apply for all nodes create the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine\AFBackupDll

Important! If "AFBackupDll" sub-key is not available, then you need to manually add sub-key AFBackupDll under engine as Engine\AFBackupDll\ and then add DWORD FallbackToSWSnapshot under AFBackupDll.

4. Save the plan and submit the backup job.

The backup job runs using the hardware snapshot.
