Instant access restore of a VMAX storage group backup

A Storage Direct host instant access restore enables you to mount the primary or replicated storage group snapshot backup, which is on a protection storage system, to the FTS devices which are the resource storage groups, in order to mask to the host to view and recover from the backup. This restore type, also known as Export, is primarily useful for granular level restore. You can access the instant access restore option in the PowerProtect Data Manager UI.

Prerequisites

  • For a virtual environment, ensure that you add and discover the vCenter server in the PowerProtect Data Manager server.
  • When you select Export, you must specify on which host (virtual or physical) you want to mask the backup. Therefore, the WWPN for this host must be discovered. Otherwise, the host will not appear for selection.
  • Ensure that you unmount all of the LUNs in the destination storage group.

Steps

  1. In the PowerProtect Data Manager UI, go to Restore > Assets and select the VMAX Storage Groups tab.
    The Restore window displays all of the storage groups.
  2. Select the check box next to the storage group that contains the backup, and click View Copies.
    You can also use the Search field, the filter in the Name column to locate a specific storage group.
    The Restore > Assets window provides a map view in the left pane and copy details in the right pane.

    When you select a specific location in the left pane to view the copies, for example, on a protection storage system, the copies on that system are displayed in the right pane.

  3. In the left pane, click the first DD icon to display the copies on the primary protection storage system, or the second DD to display the replica copies on the secondary protection storage system.
  4. In the right pane, select the check box next to the storage group snapshot backup or replica that you want to restore, and then click Restore.
    The Restore wizard opens on the Select Copy page.
  5. On the Select Copy page, select Restore all the copies linked with Backup Operation if you want to restore all Storage Groups that are part of this backup, and then click Next.
    NOTE If you leave the check box unselected, the backup of only the storage group that you selected in the Restore > Assets window will be restored.
  6. On the Restore Type page, select Export, and then click Next.
  7. On the Export Host page, select the physical or virtual host that you want to mask the backup to, and then click Next.
  8. On the Summary page, click Finish.
  9. Go to the Jobs window to view the entry for the instant access storage group restore and verify when the mount completes successfully. An instant access job will indicate Instant access for backup ID storage group ID. You can also click Detail icon next to the job to verify what steps have been performed, for example, when the instant access session has been created.

Results

To monitor and manage the instant access storage group restores, select Restore > Running Activities, and then click the Instant Access Sessions tab. When finished with the session, select the session and click Delete in order to unmount the backup from the host.
NOTE You cannot extend or migrate an instant access storage group session. Also, there is no default retention period. The session remains mounted until deleted.
