I think I'd try to avoid changing the mounts around while logged in;
that seems to me a recipe for confused software. In particular,
unmounting it while it's in use isn't going to work.

And I think I'd leave the backup directory mounted on both /home/peter
and /home/peter.bak all the time, and just mount the removable drive
over the top.
