PVE Backup to PBS tries to "prune" now and get permission error

[Apollon77]

hey,

I'm using PBS on PVE since some time and everything was ok. Yesterday I updated to the latest 0.9.4-1 and got a backup error. Basically it seems that since the last version PVE tries to call "prune" at the end of the backups.

INFO: running 'proxmox-backup-client prune' for 'ct/306'
ERROR: prune 'ct/306': proxmox-backup-client failed: Error: permission check failed
ERROR: Backup of VM 306 failed - error pruning backups - check log
INFO: Failed at 2020-10-30 10:00:34
INFO: Backup job finished with errors

I use a permission limited user in pbs that only have DatastoreBackup. In my eyes this should be enough because I do not want to give too high permissions.

So do I need to make that user now a PowerUser or what to allow why PVE is doing?! Or should you not do a config switch if prune should be done? (because PBS normally has it's schedules for this

yeah, pruning should be skipped if the storage and backup job are not configured for pruning..

Same issue here. Verified storage Max Backups is set to '0'

Same thing for me.

So you will fix that in a coming update?

 

[fabian]

yes. in the meantime you can add --remove 0 to the command line, it should stop pruning then.

You 've to back your data-store with Power-user Role. this role include Backup and Prune privilege.
