The following limitations and conditions exist for jobs using Granular Recovery Technology (GRT):
The feature is limited to certain versions of SharePoint Server and Windows Server.
See Configurations that are supported for SharePoint Granular Recovery.
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).
Granular recovery of the SharePoint 2010 Central Administration Web site and the Shared Services Administration Web site is not supported.
