This is an interesting failure.  rmtree is mean to to remove everything
regardless, so what is remaining in the not-empty directory?

Is there an immutable file somehow?

Does a shell 'rm -rf' work on that directory?

The logs indicate it got as far as putting files into the backup, it is
possible all the files were added, or otherwise that there was a
failure adding some file, we can't tell from the logs which.

It is a long shot, but consider/rule out filesystem corruption - run
the backup on another filesystem perhaps?
