just to highlight the trap, as I've fallen into it too:

if $variable is unset for some reason, 'rm "$variable".*' becomes
'rm "".*' which is processed by the shell as 'rm .*'

lesson: be very careful with rm, try to anticiapte failure modes, and
set up that rsync cron job to backup your home directory.
