Recently, there have been regular (once a few days, sometimes once a day) backup failures on proxmox backup server.

The log is below, in general, the machine is locked and has not been unblocked after. Subsequent viral machines are also all failed (Permission denied).

What can I do, do I need additional information or logs?

pve 8.0.3
pbs 3.0-1

Hi, please append the journal from around the time the error happens from the PBS host and the PVE host, journalctl --since <DATETIME> --until <DATETIME> > journal.txt.
