This extra thread is sort of ridiculous. In the previous thread you've
shown already that /media/backup is a separate mount point:

Now you try to remount /, which makes no sense because you would need
to (re)mount /media/backup properly. Not /. You could avoid confusion
like this if you provided enough details in all your posts rather than
letting list members do the tedious guess-work. ;)
