Hello,

I have been using Proxmox for 2 years now. Good tool.

With hindsight, one thing bothers me is the VM lock during backup. It happens often (about once a week) with VM windows or linux. No problem with LXC. I know the magic command to unlock (qm unlock vmID) but that as a consequence to make the vm unusable until we intervened.

How to solve this problem and avoid lock?

Thank you.
 
I share the error message. Maybe that explains the origin of the problem :
