Permission trouble on files

1

Hi. I was going to try and get to have a backup of my PBS (Proxmox Backup Server) files to the cloud provider pcloud.

My files is on my unraid 7 NAS. I have a docker instance of Duplicati v. 2.2.0.0_stable_2025-10-23 running as a docker app.

I seem to get into a file permission issue, and dont really know how to fix it.
After running a backup job i get this warning in the logs:

"2025-10-26 15:03:09 +01 - [Warning-Duplicati.Library.Main.Operation.Backup.FileEnumerationProcess-PermissionDenied]: Excluding path due to permission denied: /source/PBS/backups/prox2/.chunks/\nUnauthorizedAccessException: Access to the path '/source/PBS/backups/prox2/.chunks' is denied."

Anyone got a clue on how i should try and fix this problem?

Changing the owner of the duplicati docker to UID/GID 34:34, made things work. I am worried for other future backups not ran by PBS, but for now this worked

Welcome to the forum @rayalot

I don’t follow that. Something else is making backup that Duplicati will back up again?

Many people run Duplicati as root. LinuxServer.io image tends to run very restrictively.
Duplicati image used to run only as root, but is getting enhanced to allow UID controls.

EDIT 1:

If you want to see Duplicati user from its GUI, see About → System info → UserName.

Yes, the backup is made by Proxmox Backup Server. Duplicati is just copying the backup made by PBS.
It’s the linuxserver docker image I run.
