Restoring data to an RSG in Exchange 2007

•
Supported Backup Methods: ESE and VSS
The procedures that follow illustrate the steps required to establish an RSG in Exchange 2007 as well as how to use NetVault Backup to restore backed-up data to it.
Creating an RSG
Setting up an RSG involves two basic steps:
•
Creating an RSG.
•
Adding databases to restore.
You can find complete instructions for these procedures in the relevant Microsoft Exchange documentation. For more information, see Working with Recovery Storage Groups in Exchange 2007 at http://www.msexchange.org/tutorials/Working-Recovery-Storage-Groups-Exchange-2007.html?printversion.
Restoring data to an RSG
With the RSG successfully created and the appropriate databases added to it, you can begin restore procedures of the applicable data to the RSG.
 
* 
IMPORTANT: To avoid complications in a restore of this type, Dell recommends that you restore individual Storage Groups on a one-per-job basis; that is, only select an individual Storage Group for inclusion in a single restore job.
Depending on your backup-and-recovery strategy, see the applicable procedure in Examples of restore sequences for instructions on restoring data items in a backup saveset to an RSG.
During an RSG restore operation the Plug‑in for Exchange will redirect recovered data to the RSG rather than overwriting the original database.
Viewing data restored to an RSG
For Exchange Server 2007, the Exchange Troubleshooting Assistant (ExTRA) and Windows PowerShell® included with Exchange 2007 may be used to extract data from a database in an RSG. For information on using these utilities, see the relevant Exchange documentation. For additional information, see How to Recover a Mailbox by Using a Recovery Storage Group at: http://technet.microsoft.com/en-us/library/aa997694.aspx

Restoring data to a Recovery Database (RDB) in Exchange 2010 and later

Because Exchange 2010 and later do not use Storage Groups, it includes the RDB feature as a replacement for the RSG. An RDB is similar to RSG in that it 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 Recovery Databases at http://technet.microsoft.com/en-us/library/dd876954.aspx.
Restoring data to an RDB
•
Supported Backup Method: VSS only
The following procedures illustrate the steps required to establish an RDB in Exchange 2010 or later, as well as how to use NetVault Backup to restore backed-up data to it. To create an RDB, you must use the Exchange Management Shell.
To create an RDB:
1
Open the Exchange Management Shell.
2
Enter the following command:
New-MailboxDatabase ‑Recovery ‑Name <RDB_Name> ‑Server <Exchange_Server_Name>
You can find complete instructions for this procedure in the relevant Microsoft Exchange documentation. For more information, see Create a Recovery Database at 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 Storage Groups/Mailbox Databases. After you select the Rename to check box, enter the name of the RDB in the text box to direct the backup to the RDB.
Extracting the data from the RDB
After you have restored the database to the RDB, use the Exchange Management Shell to extract the data from the RDB to the active mailboxes.
The following example restores a mailbox for a user named Scott from the RDB named RDB1:
Restore-Mailbox ‑Identity Scott ‑RecoveryDatabase RDB1
You can find complete instructions for this procedure in the relevant Microsoft Exchange documentation. For more information, see Restore Data Using a Recovery Database at http://technet.microsoft.com/en-us/library/ee332351.aspx.

Performing a disaster recovery of an Exchange Server

This section briefly describes how to recover an Exchange system by using backups performed with the Plug‑in for Exchange. You can use this procedure to rebuild an Exchange Server if the original was destroyed or is otherwise unusable. If you are rebuilding an Exchange Server, the Active Directory service should be available in Disaster Recovery Mode.
The restore sequence performed should bring the Exchange Server up to the most current point before the failure of the Exchange Server. This sequence could include restoring a Full Backup, a Full Backup plus a Differential Backup, or a Full Backup plus Incremental Backups depending on your Exchange Server backup-and-recovery strategy. However, Dell strongly recommends that you consult the Microsoft documentation for the Exchange version in use for complete details on the proper way to perform this type of recovery.

To perform the restore:
1
Reinstall the OS.
The OS and service pack must be identical to the OS and service pack that was installed when the backup saveset was created.
2
Reinstall Exchange in Recovery Mode.
The Exchange version, edition, and service pack must be identical to the version, edition, and service pack of Exchange that was installed when the backup saveset was created. For complete instructions, see the relevant Microsoft Exchange documentation identified earlier.
3
If you are using Exchange 2007, create an Exchange Server.
This server functions as the target of the relocation restore. If the original Exchange Server had continuous replication such as LCR, CCR, or SCR, continuous replication should not be configured before performing the restore. Additionally, the new Exchange Server must be accessible to the Plug‑in for Exchange on the new restore target.
4
Reinstall the NetVault Backup Client and the Plug‑in for Exchange.
5
Add the Exchange Server to the NetVault Backup Domain as a Client.
For more information, see the Dell NetVault Backup Administrator’s Guide.
6
For details on restoring Exchange backups, see Restoring data using the plug-in.
 
* 
IMPORTANT: Because continuous replication is not enabled before initiating the restore, it is not necessary to disable or resume and update replication when restoring in a disaster-recovery scenario.
7
If applicable, enable continuous replication including LCR, CCR, and SCR.

Recovering to an alternate Exchange Server

The Plug‑in for Exchange also lets you take the backup of a Storage Group/Mailbox Database performed on one Exchange Server and restore it to a secondary Exchange Server. This option can be beneficial when you must recover a Storage Group/Mailbox Database to access its contents while leaving the initial Exchange Server untouched and operational. In addition, restoring to a secondary Exchange Server can be a good method for testing the integrity of backed-up data without interfering with a running Exchange Server. This section offers instructions on restoring Full, Incremental, and Differential Backup types to a secondary Exchange Server.
