The Exchange Agent supports the Microsoft Volume Shadow Copy Service (VSS), a snapshot provider service only available on Windows Server 2003 or later. Using VSS, a point in time view of the Exchange database is snapped and then backed up, leaving the actual Exchange database open and available for users.

If the Advanced Disk-based Backup Option (ADBO) is installed on the media server, you can use the Backup Exec Granular Recovery Technology (GRT) option when you create an offhost backup for the Information Store.
