Hello @miednr

var/libs/docker/overlay2 takes 47 GiB and var/libs/docker/volumes takes 12 GiB. That all seem quite much. What could be the reason?
I can not evaluate if this disk usage is appropriate or not without knowledge about what apps you have installed.
But does not look to bad.

It may be possible, that I was entering the wrong path first, and it did "restore" not only the WordPress-Instance, but also Ubuntu and all the other 18 apps to this container. Is this possible?
If you used the normal Cloudron app restore, this would not be possible.
A Cloudron app backup does only include the app data and not the whole system.

What could I do? Should I delete the whole container? Or may I "repair it" by deleting obsolete files?
If a WordPress grows to such an extent without our knowledge, I would advise verifying what is happening.
This is unusual behaviour and might be a hint that something is wrong with your WordPress, may even be compromised.
