Backup to server is failing

[herrJones]

Hello,

I replaced a few months ago a server in my proxmox cluster (3 servers, proxmox backup server not included)
At first sight, everything seems to be running OK, unless I try to do a backup for some vm's / containers.

The error I get:
ERROR: VM 125 qmp command 'backup' failed - backup connect failed: command error: backup owner check failed (root@pam != backup@pbs)

(I have no idea where I could change this behaviour, tried looking in the config files on the servers itself)(No idea if I can safely change this...)
I can however, backup these vm's/containers to another backup datastore on the backup server (mounted volume on an external disk).
But that requires leaving that disk powered the whole time

The backup server itself doesn't seem to complain.
Any ideas how to solve this problem?

Kind regards,

Jan

each backup group has an owner in PBS, and to prevent accidents, you are not allowed to overwrite backups owned by another user. so either you need to change the owner on the PBS side, or you made a mistake when setting up PBS access on the PVE side and used the wrong login there..

Thanks!
Got it working again
