One of the really cool functions of BE is the Granular Recovery Technology (GRT). By the way, anytime you need more information on any aspect of BE please see the Backup Exec for Windows Servers Administrator’s Guide. In fact, don’t take my word for it, download from here:
http://seer.entsupport.symantec.com/docs/308400.htmJust a few tips to help you get the best out of BE’s GRT:
- Review the requirements for staging locations in the Administrator’s Guide.
- You must use a staging location for GRT-enabled jobs in the following scenarios:
- You back up to or restore from a volume with file size limitations.
- You restore granular items from tape.
- You run an off-host backup job.
- You are better off creating a separate backup-to-disk folder specifically for all GRT enabled backup jobs - this really simplifies media management. You will need to manage the IMG media that GRT enabled jobs create differently than other backup-to-disk media.
- Don’t allocate a maximum size for backup-to-disk files. If you do then you are in danger of getting failed jobs because of low disk space. This is because the backup-to-disk file often occupies extra space since GRT information is stored in IMG media and Backup Exec will only create a backup-to-disk file that is as large as the size that you specified.
- If you are using frequent incremental GRT enabled jobs it is a really good idea to run a full GRT enabled backup job every so often. This is because each incremental GRT enabled job requires a small amount of internal storage. If this storage amount increases too much, it can affect system resources. When you run the full GRT enabled backup job, you make available the storage space that has accumulated from incremental jobs.
12.5 delivers GRT for Exchange, Active Directory, SharePoint Server, and SharePoint Services which gives you the ability to recover granular data quickly and efficiently from a single-pass backup. It means, for example, that you do not have to run Exchange mailbox backups to recover granular data, including documents, list items and user attributes, or properties.
