When we want to revert to the old backup, we get the following error.
Our total disk capacity is enaugh.
When we returned to the backup 4 days ago, we did not detect any problems.
What could be the reason for this?
Can you enable thin provisioning on PVE or only on Proxmox backup server? I'm looking at datacenter-storage, and the zfs pools but cant find an option to enable thin provisioning
