Yes, it did but something strange happened (2 e.g. enforcing was used) 
_or_ some file was not backed up at all (4 e.g. because it's not 
readable) or had some warning (8 e.g. because some attributes couldn't 
be read or applied).

This said, it is important to understand that it is work in progress and 
that the codes aren't yet everywhere implemented, especially the file 
related ones.

Ah, I didn't realize, this needs indeed to be fixed.
