Won't backup any files.

[fire-hawk-86]

In the resulting .tar file, there only one file .meta.mint with the line num_files:0.
Is it maybe conflicting with timeshift? Becauce Timeshift excludes the home directories.
Where can I find the configuration file of mintbackup

Maybe something broke when I tried to add invisible directories together with invisible files, instead of doing two separate actions.

Edit: Works now as expected.
It was a new Linux installation. So there is not much to backup, I guess.
