It wouldnt be too difficult to write a perl script that periodically
checked the textdump for such changes, and could in addition make a
backup copy (and do other nifty maintenace things). Of course how much
processor time would be eaten up by it, I'm not sure. You could even
(I think) modify backup so that it called this script first, and only
the site admin could turn it off. (of course, being able to just
change shutdown would make that useless). But if the script didnt
overwrite the backup if certain criteria were met, and could kill the
server if others were met, then it might be useful for a high-security

Of course, I want to get a running server and DB before I work on
extra security measures :)
