How do I update only new files backup?
I accidentally backed up to /home/username/username how to I copy that folder so it goes in /home/username/ and that it only moves new or recently changed files??
Can't Deja-Dup do it?
I am not quite sure I understand the problem but here is a command to "move" (you probably do not want to "copy") every under /home/username/username to /home/username/:
$ mv /home/username/username/* /home/username/
And, yes, Déjà-Dup is great: https://trisquel.info/forum/buck-using-rsync#comment-96275
Maybe the '-u' option would be of interest
$ mv -u /home/username/username/* /home/username/
From mv manual:
-u, --update
move only when the SOURCE file is newer than the destination file or when the destination file is missing
I just used lucky backup instead and just modify the option to not delete files on destination not in source folder.
