About restoring snapshot backups

From a snapshot backup you can restore the Microsoft Information Store, Exchange 2010 databases, and Exchange 2007 and earlier storage groups and storage group databases. If you enabled Granular Recovery Technology (GRT) for the backup, you can also restore mailbox and public folder items from the backup.

Note the following when you restore snapshot backups:

(Exchange 2007 and earlier) All databases in a storage group must be dismounted before you begin a restore operation. You can instruct NetBackup to dismount the databases before the restore begins.
All of the images you select for the restore must be from snapshot backups.
Only Exchange 2007 allows snapshot restores to the Recovery Storage Group (RSG).
Exchange 2010 allows restores to the Recovery Database (RDB).
(Exchange 2007 and later) For Instant Recovery restores:

Select Normal Backup even if you want to perform volume rollback. NetBackup automatically rolls back volumes whenever it is appropriate
One of the following occurs:
- NetBackup snaps back (resyncs) the selected database volumes from the snapshot to the original volume.
- NetBackup copies back the files of the selected databases from the snapped volume to the original volume
