Renaming Mailbox Databases in Exchange 2010

The Plug‑in for Exchange allows you to rename a Mailbox Database during VSS-based restores. Renaming is useful if you do not want to overwrite the existing version and want to create a copy of the Mailbox Database. The following prerequisites are met before initiating the restore:

Ensure that the following prerequisites are met before initiating the restore:

•
Target Mailbox Database must exist: The target Mailbox Database must be created in the Exchange System Manager or Exchange Management Console.
•
Database names must be different from the original: The name of the target Mailbox Database must be different from the name of the original database.
•
Database filenames must be different from the original: The database filenames in the target Mailbox Database must be different from the database filenames used in the original Mailbox Database.
 
* 
NOTE: Due to a scripting limitation of the Windows PowerShell, the plug-in does not support the use of single or double quotation marks in Mailbox Database names.

To complete the rename process, perform the following steps.

1
After the prerequisites have been met, click Create Restore Job.
2
Select Plug‑in for Exchange from the Plugin Type list.
3
Select the Mailbox Database to restore from the backup saveset by following the instructions outlined in Selecting data for a restore, and click Next.
4
On the Create Selection Set page, click the Mailbox Database that you want to rename and select Rename from the context menu.
5
In the Rename/Relocate dialog box, enter the existing name of the target Mailbox Database in the Rename box, and click Ok.
The name of the Mailbox Database is updated to reflect the rename information in parentheses.
6
Continue with the restore procedure as explained in Setting restore and recovery options and Finalizing and submitting the restore job.
7
Open the Exchange Management Shell.
8
Run the following command:
Get-Mailbox -Database <SourceDatabase> |where {$_.ObjectClass
-NotMatch '(SystemAttendantMailbox|ExOleDbSystemMailbox)'}
| Set-Mailbox -Database <TargetDatabase>
Replace <SourceDatabase> with the name of the original database and <TargetDatabase> with the name of the destination.

Restoring data to a Recovery Database (RDB)

An RDB is a special database that is created to hold a restored database where data can be extracted without disturbing user access. The RDB enables the recovery of accidentally deleted mailboxes and other email items, as well supporting data recovery for legal inquiries.

You can find a complete description of RDBs and their usage in the relevant Microsoft Exchange documentation. For more information, see http://technet.microsoft.com/en-us/library/dd876954.aspx.

•
Supported Backup Method: VSS only

The following procedures illustrate the steps required to establish an RDB, and how to use NetVault Backup to restore backed-up data to it. To create an RDB, use the Exchange Management Shell.

Creating an RDB

1
Open the Exchange Management Shell.
2
Enter the following command:
New-MailboxDatabase ‑Recovery ‑Name <RDB_Name> ‑Server <Exchange_Server_Name>
 
* 
IMPORTANT: When you create the RDB, do not use Mount-Database. If the database is mounted, the initial Exchange Server database transaction logs are generated. These logs might interfere with the restore job and cause it to fail.

You can find complete instructions for this procedure in the relevant Microsoft Exchange documentation. For more information, see http://technet.microsoft.com/en-us/library/ee332321.aspx.

Restoring data to an RDB

With the RDB successfully created, you can restore data to it by completing the steps outlined in Renaming Mailbox Databases in Exchange 2010. Amend those steps to including the following steps:

1
After you select the Rename to check box in the Rename/Relocate dialog box, enter the name of the RDB in the text box to direct the backup to the RDB.
2
On the Create Selection Set page, click Edit Plugin Options, and select the following options on the Restore and Recovery Options tab:
•
Set ‘This database can be overwritten by a restore’ Flag for Databases
•
Perform Recovery (Enable only on Last Step in Restore Sequence)
•
Mount Databases after Recovery
3
If you created the RDB on an Exchange Server that is not the active server, select the applicable NetVault Backup Client from the Target Client list on the Create Restore Job page.
In a DAG, the plug-in automatically directs the restore job for an RDB to the active server in the cluster. If you created the RDB on an Exchange Server that is not the active server, select the client in the Exchange Server that hosts the RDB.
