Veritas NetBackup™ for Microsoft Exchange Server Administrator's Guide

To redirect an Exchange snapshot backup to another database or to the recovery database

1. The following applies to suspending replication:

   • If redirecting to another database, manually suspend replication. This step applies for any snapshot provider you use.

   • If redirecting to the RDB, NetBackup suspends replication on the target server.

2. The database or the recovery database must already exist.

   To restore to the RDB, create the RDB on an Exchange server, if necessary. Leave the RDB dismounted.

3. Open the Backup, Archive, and Restore interface.
4. Click File > Select Files and Folders to Restore > from Normal Backup.
5. Click File > Specify NetBackup Machines and Policy Type.
6. In the Specify NetBackup Machines and Policy Type dialog box, provide the following information:

   Server to use for backups and restores	Select the server that performed the restore.
   Source client for restores	Select the virtual DAG name.
   Destination clients for restores	To restore to another database in the same DAG, leave the destination client the same as the source client. NetBackup redirects the restore to the server that hosts the active copy of the database. To redirect the restore to a different DAG, indicate the DAG name where that database exists. To restore to a specific mailbox server, enter that server name. To restore to the RDB, indicate the DAG name. If the RDB exists on a standalone server, indicate that server name as the destination client. If applicable, review the notes and limitations for redirecting to a different client.
   Policy type for restores	Select MS-Exchange-Server.

7. From the NetBackup History pane, select one of the following:

   • The last full backup, or

   • The last full backup and all subsequent differential backups, or

   • The last full backup and the last cumulative backup

8. In the All Folders pane, expand Microsoft Exchange Database Availability Groups > Forest or domain name.
9. Select the database you want to restore.
10. Click Actions > Restore.
11. Change the destination path to another database or to the RDB:

    • Click the General tab.

    • Select Restore everything to a different location.

    • In the Destination box, provide the name of the alternate database you want to restore to. Or provide the name of the RDB you previously created.

      Exchange does not automatically redirect a database to its RDB, if it exists.

    
12. Click the Microsoft Exchange tab.
    
13. Check Commit after last backup set is restored.

    If you choose to restore backup images separately, you must check Commit after last backup set is restored only when you restore the last incremental backup set.

    If you do not select Commit after last backup set is restored, manually mount the database after the restore is complete.

14. 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.

15. When the restore completes, resume replication.
16. If necessary, update the mailbox database copy.
