Performing a snapshot restore of a Database Availability Group (DAG)

To perform a snapshot restore of a Database Availability Group (DAG)

  1. Manually suspend replication. This step applies for any snapshot provider you use.

  2. Dismount all Exchange databases that you want to restore.

    Or, when you perform the restore, click the Dismount database prior to restore option.

  3. Open the Backup, Archive, and Restore interface.

  4. Click File > Select Files and Folders to Restore > from Normal Backup.

  5. Select the Exchange policy type. For the source client, specify the DAG name.

  6. From the NetBackup History pane, click the backup image that contains the objects you want to restore as follows:

    • The last full backup or user-directed backup

    • The last full backup and all subsequent differential backups

    • The last full backup and the last cumulative backup

  7. In the All Folders pane, select the objects you want to restore, as follows:

    • The Database Availability Group.

      Selecting this object restores all the databases.

    • Databases.

      Expand the DAG. Then select the database(s) and log files you want to restore.

  8. Click Actions > Restore.

  9. Click the Microsoft Exchange tab.

  10. Click Start Restore.

    The restore is directed to the active Exchange database, regardless of which database was backed up. NetBackup automatically detects the Exchange server that currently contains the active Exchange database.

  11. When the restore completes, resume replication.

  12. If necessary, update the mailbox database copy.
