We had been hosting a relatively large file share on a NAS box so I was just backing up the file share on that NAS box. However, I recently migrated that over to a VHDX attached to a Windows file server. Ever since I've done that it looks like the Barracuda is now backing up the entire VHDX file every single night. The file itself is massive and takes a long time to complete the backup. This wasn't really my anticipated result. I just want to backup the changes to the file share living on the disk not the entire disk (we are only using about 50% of the disk right now) every night.
I'd just not include the large VHDX file in the backup and add a file share backup. But I don't see a way to exclude disks attached to a Hyper-V Guest OS. So if I want to backup the guest VM it seems I have to also backup all the attached disks?
Or maybe backing up the actual VM for the file server is trivial and I should just be running backup jobs for the individual file shares hosted by the server itself?
