Hi, one VM were stuck while backing up at line "INFO: issuing guest-agent 'fs-freeze' command" so I did stop the process and you see what followed next.


Code:
INFO: starting new backup job: vzdump 412 --notes-template '{{guestname}}' --storage SG8T --prune-backups 'keep-all=1' --mode snapshot --fleecing 0 --quiet 1
INFO: Starting Backup of VM 412 (qemu)

Any hint to figure why it was stuck? It is a scheduled backup running every 15 minutes and usually ending in 1-2 minutes.

After stopping the backup I did a "qm unlock 412" command to unlock it.

The next backup gone ok:
