Hello everyone, I need help with my server. Since the very beginning of my adventure with Unraid, I’ve been having issues with permissions and possibly with user(s). The permissions for almost all Docker applications—including Radarr, Sonarr, Plex, Lidarr, Prowlarr, PiHole, etc.—keep changing on their own almost every day. I don’t change anything in the settings, and Unraid runs 24/7. The next day, the above applications stop working, and the only way to fix this annoying issue is to log in to the Unraid admin panel, go to the Main > Browse Share tab, select the appdata folder, and manually change the permissions to read/write. And I have to do this every day, which is pushing me close to the decision of giving up on Unraid entirely. I’ve attached a syslog file and a screenshot. Thank you in advance for your help.

Do you run any user scripts that touch the "appdata" share?

Also you should not be changing the permissions of the appdata, doing so will break docker containers. It's possible the containers themselves are reverting permissions but since you've messed with them, it breaks when they try to revert.

To be completely honest, I’ve never used and don’t use any user scripts. The only plugin I use in my Unraid is Appdata Backup, and nothing else. I noticed that this plugin in particular started messing with my permissions. Because of that, I disabled the scheduled backups. Everything was fine for a few days—until now. It’s enough that the next day, when I get home from work and log into Unraid, I already know that the Docker applications won’t be working. Also, after using Appdata Backup, I know with 1000% certainty that the permissions will be changed and the applications will stop working

curious what path did you set for the "backup destination" in the appdata backup plugin?

I have two pools, each with a 500GB SSD. The pool named ‘cache’ is used exclusively for Docker. The pool named ‘SSD’ is used only for virtual machines (Linux Ubuntu Server and Windows Server 2025). The location for the appdata backup is: /mnt/ssd/appdatabackup/

Anyone?

appdata permissions are controller by the containers, and they can be different from container to container, and you should not attempt to change them, also for that reason, that folder cannot be accessed over SMB, only locally.

Thanks for the comments and help but I still have the same problem. Problems with Unraid directed me towards the TrueNAS and there everything works as it should the first time. Plus it's free with no limits and no assigned USB key.

The issue is you've changed permissions, the docker containers are trying to use their own permissions so it is partially reverting those permissions to what they need.

This is how docker works. You should never change permissions in the appdata share manually as it will break docker containers.

Also I noticed in your appdata backup plugin you have both /mnt/user/appdata as well as /mnt/cache/appdata where you only really need to specify /mnt/user/appdata as that location covers all disks/pools. You should remove /mnt/cache/appdata.

If this is NOT the case, best suggestion is to post a before and after screenshot of the permission changes for further evaluation.
