Working with backup sets : Microsoft Exchange Server backup sets (Windows) : Restoring a Microsoft Exchange Server backup set : Specifying the database(s)
 
Specifying the database(s)
Browse the Database Tree, select the check box(es) of the database(s) and/or individual items you want to restore, and click Next.
To view and/or select individual items, select a database and click Show Files.
To see the total size and number of files selected, select Calculate amount.
DS-Client will try to detect if a Recovery Storage Group (RSG) exists on the selected Exchange server. Depending on your network environment, this process may take a while. The Restore Now Wizard will proceed to the next screen after this process is completed.
If an RSG exists, the selected database will be restored to that location. A popup message will confirm this.
NOTE:  If the RSG on an Exchange server is the destination location, the RSG must use the name “Recovery Storage Group”.
For more information about restoring to Recovery Storage Groups, see “Restoring Microsoft Exchange 2007”.
