Maybe I'm misreading your post...  But it sounds like you are trying to put your backup storage in the same physical box as the VMs you want to back up.

That's a really bad idea.  If you have a hardware failure, you could lose both the VMs *and* the backups in one fell swoop.

I strongly recommend that you keep your backup target on separate hardware -- leave it on the Pi if your backups don't need much bandwidth on the network.  Build a separate box if needed.

I am not familiar with OpenMediaVault's NFS config parameters, so I can't give specific advice there.  I use TrueNAS to host the storage of my VMs over NFS. I then use ZFS replication to perform the backups.  This is one thing I plan to change in the future, but it's working well for now.

I am also not familiar with the way Proxmox does its connections.  So this could be a misconfig on either end.  Are you using NFS 3 or NFS 4?  NFS 4 allows for more security, but in my little private homelab, I run NFS 3 for simplicity.

Sorry that I don't have more constructive advice.  I just wanted to jump in and advise to NOT put your backups on the same hardware as the stuff you are backing up.

Hope this helps (some),

Chad
