Error: Entry \\ not found in snapshot

Hi all,

We used HV Backup on several systems and it works great. Thanks for releasing it.

On a new 2012 Hyper-V setup we're running into the error below. We're running version 1.0 beta1.

We're backing up 4 VMs. It will back up a few and then throw this error. If I reboot the host I can back up a few again and then the error will pop up. Rerunning the job won't work unless I reboot the host.

What doesn't make sense is where CRM4-AutoRecovery.avhdx is coming from or why this error happens.

Error: Entry "\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy4\VHDs\CRM 4\CRM4-AutoRecovery.avhdx" not found in snapshot

I started seeing the same error. The path is probably odd because it is a shadowcopy.
The real problem is that looks like the file is missing. I don't even know why is it supposed to exist, since that VM doesn't have snapshots at all and file doesn't exist on disk.
