The following limitations and conditions exist for jobs using Granular Recovery Technology (GRT):
The feature is limited to certain versions of Exchange Server and Windows Server.
See Configurations that are supported for Exchange Granular Recovery.
The NetBackup media and server client must have NetBackup 6.5.3 or later.
You must configure NetBackup for browsing and restores of individual mailboxes and public folders.
See About configuring the NetBackup Client Service for backups and restores that use Granular Restore Technology (GRT) or MAPI.
This feature only supports full and user-directed backups. NetBackup lets you create a complete policy for disaster recovery, with all the various types of schedules. However, you cannot restore individual items from an incremental backup.
Backups must be made to a disk storage unit, not to tape, and restores that use GRT must be made from a disk storage unit. You can manually duplicate the backup image to disk, but you cannot restore from the tape copy.
See About disk storage units and restores using Granular Recovery Technology (GRT).
If you want to use instant recovery and GRT, you must select in the schedule properties.
Exchange Server provides a feature to retain deleted items for a period of time after you "permanently" delete them. Because the deleted items still exist, NetBackup includes them in the backup image. NetBackup displays these items when you browse the granular backup image and you can restore these items.
