Guidelines for restoring from a SnapManager backup copy

You must follow some guidelines about the type of restore operation, the restore destination, and naming of the Storage Groups before you begin to restore from a backup.

Use the most recent backup copy for an up-to-the-minute restore process; otherwise, more transaction logs need to be replayed, and the restore process takes more time.
The most recent backup copy's name contains recent if you did not use the unique naming convention; otherwise, it uses the most recent timestamp.
You can restore an entire Storage Group or, if you configured your Exchange Server storage groups and databases appropriately, individual databases.
If you need to restore more than one Storage Group, run SnapManager Restore more than once.
If you rename a Storage Group after backing it up, you cannot recover it from that backup copy.
If you must recover a Storage Group from a backup copy made before the Storage Group was renamed, return the Storage Group to its former name, then recover it from the backup copy by the same name.
If you rename a Storage Group, make sure that you back it up as soon as possible.
Note: When you rename a Storage Group, unmount all of the databases in that Storage Group. After they are all unmounted, you can remount the databases. At this point, Exchange recognizes the new Storage Group name, and SnapManager can make new backup copies.
If you restore the Storage Group to the Recovery Storage Group, you can perform only a point-in-time restore process.
Store all databases that reside on the same LUN together.
