Started testing Vertical Backup this weekend and my first VM backup went fine (if a little slow; 6MB/s, which I don’t know if is normal with a Windows/cygwin SFTP storage guest on the same host, but I’ll investigate that for later…).
My second test was a 2012 R2 Exchange 2013 Server VM but which errored out on snapshot creation:

The snapshots are created just fine, it’s just that Vertical Backup seems to think they weren’t. I can create snapshots for this VM in the vSphere Client, and with the vim-cmd vmsvc/snapshot.create command above. It works without issue, but verticalbackup goes no further.
There are no existing snapshots and I’ve already ran a consolidation as mentioned in other posts.
The backup completes OK if I exclude one of the disks (it has 2; 120GB OS and a 160GB thinly provisioned data disk). If I exclude the second disk, it runs and the OS disk is backed up. The second disk seems problematic. I’ve also tried --no-quiesce, doesn’t make a difference.
Here’s a (slightly sanitised) copy of the VMs vmware.log file, but I can’t find anything wrong.
Any help is appreciated.
