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:

  1. Review the requirements for staging locations in the Administrator’s Guide.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

I've configured GRT to be able to restore individual mail items, however I don't see any mailbox
within the restore pane ? Can someone explain a consice and working method to backup and
restore emails successfully ?

Hi

If you are not able to see individual mailboxes in restore selections It may be the account that has insufficient credentials
Check
1) In backup job properties >>Microsoft exchange>> GRT opton should be checked
2) The account with which you are backing up exchange should have a active mailbox.( i.e atlest you have opened it once using OWA or you have sent an email to that account)
3) The mailbox should not be hidden from Global address list (http://support.veritas.com/docs/243328 )
4)the account name should be unique i.e when you go to active directory users and computers and click on find, and type just first 4 letters of the username and click find - Only one name should be displayed
if there are multiple names- the account is not valid for GRT backups (http://support.veritas.com/docs/256537 )
5)If you have exchange 2003
open the system manager >>right click on your enterprise name >>delegate control
aand ensure that your user is listed with Exchange Full Administrator  rights
6)If you have exchange 2007. In the Exchange Management Console, select Organization Configuration
Right click on Organization Configuration and select Add Exchange Administrator,On the Add Exchange Administrator page, click Browse and select the user Select the Exchange Server Administrator Role and click Add
7) Additionally only for exchange 2007 backups
Confirm that the Microsoft Exchange Server MAPI Client and Collaboration Data Objects are installed on the Exchange 2007 Server.
http://www.microsoft.com/downloads/details.aspx?Fa...
The Microsoft Exchange 2007 Management Tools are installed on the Backup Exec server.
32 bit - http://www.microsoft.com/downloads/details.aspx?fa...
64 bit - To download the 64-bit version of the management tools, use the same media or download that you used to install Exchange 2007

 So, Backup Exec copies the entire backup set or sets to the staging area. It does not matter what it is backing up.
The staging area must have enough disk space for the entire backup set or sets from which you want to restore an individual item.
Before you use a tape device for a GRT-enabled backup, to have to ensure that there is sufficient disk space is available to perform a restore.
Backup Exec deletes the data from the staging area when the restore job is complete.
From what I can gather from Tech Support most of the failures relate to insufficient disk space when the data set is restored from tape to the disk staging area.
Generally, I would have said that GRT from tape is not advisable.
I would let Tech Support do their best to sort out. In the meantime here is a forum on BE GRT that could be of assistance.
http://www.symantec.com/connect/backup-and-archivi...
pick out BE on the drop down menu.
Should be seamless, but you can only do a granular restore if you had the GRT option selected for the backup. So, if you went from 11d with GRT to 12.5 with GRT you restore of an 11d backup in 12.5 should be fine.
