proxmox-backup-proxy rrd EINVAL error

[lifeboy]

I'm getting the error below after something happened (it was not happening before) and not sure that I changed anything deliberately.
It prevent the status graphs (rrd, right?) to be displayed on the PBS administration section.

Hi!
sadly this message is very vague and there could be a few points where this error would arise. You could try checking all the permissions though. Check if the directory `/var/lib/proxmox-backup/rrdb` (and all the containing files) have the correct owner `backup:backup` and the read and write permissions are set.
