You can restore backup sets from an archive created by third-party software to the same Storage Group or server or to the Recovery Storage Group or Recovery Database. Using the Recovery Storage Group or Recovery Database enables you to mount a mailbox store copy on a production server and recover data within the restored mailbox while the current mailbox store is still running.
While performing a restore operation from an archive, restore the archived SnapInfo directory to a temporary location. This SnapInfo directory must be part of the same backup set as the restored LUN that contains the Exchange databases. The restored SnapInfo directory must have the SnapInfo file and the .xml files.
Ensure that you have ready the SnapInfo directory path for the backup set that you want to restore.
