You would do those commands from xterm.. not from Chroot - although it wouldn't really matter as long as you were the user "user" and not root in the debian chroot (because he mounts the home drive over /home). But yeah.. simple: use xterm.

Make those directories by hand.

When I said "for the copy" it was a bit out of place.. sorry.. I had submitted my original and then saw your post about how to copy the backups over.. so INSTEAD of manually recreating the directories in the first half.. if you know the FULL PATH to the backup directory in /media/mmc1 .. you would run that copy command from xterm, as user. If you don't know the full path.. try:

If that outputs a path for you then copy/paste that path into the cp -pr command.
