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.

    http://technet.microsoft.com/en-us/library/dd298159.aspx

  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 File > Specify NetBackup Machines and Policy Type.
  6. In the Specify NetBackup Machines and Policy Type dialog box, provide the following information:
    • The server that performed the restore.

    • For the source client, select the DAG virtual name.

      See About selecting a source client for an Exchange Server backup operation.

    • For the policy type, select MS-Exchange-Server.

  7. 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

  8. In the All Folders pane, choose the objects you want to restore.
    • For restores from a VMware policy, Exchange databases are displayed under the node Microsoft Exchange Database Availability Groups. You can restore the following objects:

      • The Database Availability Group.

        Expand Microsoft Exchange Database Availability Groups and select DAG_Name. When you select this object, NetBackup restores all the databases.

      • Databases.

        Expand Microsoft Exchange Database Availability Groups > DAG_Name > Microsoft Information Store. Then select the database(s) and log files you want to restore.

    • For restores from an Exchange policy, Exchange databases are displayed under the node Microsoft Information Store. You can restore the following objects:

      • The Microsoft Information Store.

        Click the check box next to Microsoft Information Store.

      • Databases.

        Select Microsoft Information Store. Then select the database(s) and log files you want to restore.

  9. Click Actions > Restore.
  10. Click the Microsoft Exchange tab.

  11. 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.

  12. When the restore completes, resume replication.
  13. If necessary, update the mailbox database copy.
