during backup No space left on device at ..., / Failed to open system journal: No space left on device

Do you have an idea how to solve this problem? Maybe add some memory space to pve-root? I can't start a new VM and create a user because this partition is full.

Well, you have 2.5TB in /mnt, which is normally empty (it is only a place to mount external storage). Maybe you can move whatever is there to somewhere else, like an external storage? Also 3.7 TB in /var, that is probably ISO files and the like that can also be removed/moved.

Backing up to /mnt is a really bad idea unless you then move those files somewhere else. It would be better to mount some external storage there and back up to that.

To get more relevant information from "du" use

~# man du |grep one
       -x, --one-file-system

My personal suspicion follows @BobhWasatch regarding "/var/", if it is not a separate mountpoint ...
