Granular information is only cataloged for a backup image that is made to a disk storage unit. A backup that is made directly to tape does not contain granular information. You can duplicate the image to tape, but you cannot directly back up to tape. If you configure backups to a disk storage unit, no further configuration is required. You can only perform restores of individual items using Granular Recovery Technology (GRT) if the backup resides on a disk storage unit.
