Hi,

Hello, i got this error while trying to backip a ct :

the log you posted is for a restore task.

recovering backed-up configuration from '/dev/vzdump-lxc-101-2024_01_19-11_50_26.tar'

/dev is a very unusual place to store your backups. I'd suggest you move them somewhere else and try again. What is the exact command you used to attempt the restore?

You should monitor the space usage on your LVM-Thin pool. Can be done in the UI or using the command lvs and looking at the Data% column.
