Hello
I have a quick couple of questions about GRT for Exchange that I hope someone could help clarify for me please.
I have taken the below paragraph extract from the ‘Exchange Server Admin Guide’ and I think I have understood it correctly but I would like to ask someone in the know just to be sure!
Disk storage units supported with Exchange Granular Recovery Technology (GRT) Granular backups must be made to a supported disk device. During the backup operation, the mailbox name or top public folder is catalogued. When you duplicate ( -bc_only ) a backup, NetBackup catalogues the entire contents of the backup image and the duplication can be targeted to any media. When you perform a restore, the primary backup image must exist on a supported disk media. You may need to perform another duplicate operation to copy the backup to disk.
So
Method we wish to use.
Our questions!
Is the method we wish to use correct?
When the primary image (image on disk) expires and the duplicated image becomes primary copy 2 can we still restore emails and folders? Does copy 2 become the primary like usual duplications.
The extract above is a bit confusing does it require the backup to be on disk? Do we need to import from tape before we perform a restore? Will we be able to recover historical GRT Exchange backups from 3 months ago using this method?
Thanks in advance for you advice

Correction to point 3 in your method:
To restore from a couple of months ago – we would need to duplicate the whole GRT Exchange backup image from tape back to the storage for restore.
For item-level restore, the image needs to be on disk.

Hi Marianne
Ah as the original image has expired on disk. We would need to duplicate the image to disk and set as primary image, then we can recover individual emails.
Thanks for you assistance and prompt response!
