You can enable the Backup Exec Granular Recovery Technology (GRT) option for offhost backups of Exchange resources. When you select the GRT option for a backup, Backup Exec collects additional information for the catalog. This information lets you restore individual mailboxes, mail messages, and public folders from Information Store backups.
Offhost backup does not support the Exchange Server backup jobs that are configured to use Symantec Continuous Protection Server (CPS).
You should perform consistency checks before you run an offhost backup.

Check Use Backup Exec Granular Recovery Technology (GRT) to enable the restore of individual mailboxes, mail messages, and public folders from Information Store backups.
If you send the job to a backup-to-disk folder with file size limitations, ensure that Backup Exec can stage temporary metadata on the default path of C:\temp.
Select Automatic - Use hardware if available; otherwise use software.
If you include resources that are not supported for offhost backup, check the following check box: Process logical volumes for offhost backup one at a time. This allows the job to complete with errors.
