Backup stops VM but it restarts and backup fails

[jaytee129]

I've set up a backup job that is set to "stop" mode, which does stop running VM but then it restarts the VM and the backup end up failing.

What am I doing wrong.

your storage goes down during the backup apparently ..

oh, yes, my bad. My NFS storage is going through the VM in question (Sophos UTM). I will need to attach an external USB drive to back that one up while stopped.
Thanks.
