Do I need GRT enabled to perform differential backup of Hyper-V Virtual Machine ?
I wasn't able to find a clear answer anywhere and we are currently running Backup Exec 2010 so I cannot test this for myself.
I am not interrested in GRT backups, my backups are full images without the possibility to restore single items from the image.
(Sure, it could be great but the trade-off in longer backup jobs is a no-go)
That brings me to the questions,
a) with GRT disabled, will Backup Exec 2012 (or newer versions) be able to perform differential backup of a Hyper-V Virtual Machine image ?
b) if yes, how will it affect backup job length ?
