I can run the scripts by hand but I have to do everything else (logging, rollovers, notifications, etc.) by hand too, that is what I wanted to avoid.
Permissions are not a big deal inside the containers and even If there is an issue, this is for my home nas. I don’t really care If I have to spend a couple of hours to fix broken permissions after restoring something from a backup.
That seems like the solution I was looking for. Google wasn’t really helpful for me here :).
