Why root permissions for execution of a backup job?

[steff123]

Hey, a scheduled backup job failed because the backup server wasn't up and I like execute the job manually in the pve web-ui. But I get the following error.
How can reexecute the job without login as root in the ui?

Some errors have been encountered:
node03: Parameter verification failed. (400)

prune-backups: Only root may set this option.
node01: Parameter verification failed. (400)

prune-backups: Only root may set this option.

Someone answered but deleted the reply. You can find the pveversion output below.
If it is necessary to be root@pam, is it possible to rerun a failed job from the command line with the parameters I can found in /etc/pve/jobs.cfg? Is there something like a command rerunjob backup-foobar where backup-foobar is the identifier in the jobs.cfg?
