Proxmox 4.4. I have a Windows Server 2012 R2 VM cloned from a newly created template. It is on a ZFS storage. If I try to back it up, it proceeds to the step where it says 'INFO: creating archive ...', and then sits there. If I stop it, it seems to leave the VM locked, as I can't do anything else without 'qm unlock VMID'. I haven't confirmed all other VMs can be backed up, but I did do 3 without issue (including the template VM.) Any tips as to where to look would be appreciated, thanks!
