As Eric suggests, the problem is almost certainly something to do with
rsync. It can be quite picky about what has changed and what has not; a
close read of the man page can pay off. Filesystem type and option
settings are worth checking.

It may also be worth noting that it's pretty easy to set up a bogus
directory tree somewhere and then make a bogus vault somewhere well away
from your existing backups. That may reduce the risks of any accidental
damage as well as allowing test runs to complete more quickly!

Cheers, Dave
