Any idea what this error is and what might have caused it?

The backup is still running?

The backup is still running?

Yes, the WebGUI shows backup still running. Even if i try to stop it it gives the error message instead of stopping. After VM forcefully restarted, backup does stops on its own.

What kind of backup storage - maybe NFS blocked?

What kind of backup storage - maybe NFS blocked?

FreeNAS NFS Shared Storage. Issue with NFS is what i am thinking. Although NFS host did not show any activity while Proxmox was still trying to back up. I would like add that Backup LAN is fully separated with their own NIC, Switches and Subnet. So there are no additional bandwidth sharing. This kind of issue i have only seen with NFS only. Tried to reproduce similar incident backing up same VM on CephFS Shared Storage. Although i/o is not the great, it never broke the backup even with 3 backups from 3 Proxmox nodes running simultaneously.
