That's the clever thing about rdiff-backup saving reverse diffs... if
the file hasn't changed, it doesn't consume any space.  There can
still be a subtle advantage over rsync, because if something bad
happens (like files or directory being inadvertently deleted) to the
source and you don't notice before the cron job does the periodic
rsync you end up with a second copy of that new tree... while
rdiff-backup would let you back-up in time before the accident.
