Heh. "Let the punishment fit the crime" ... and let the backup
strategy fit the risk model.

Might wanna keep an eye on the DVD's. I hear the dyes aren't quite as
stable and long-lived as the manufacturers claim. I've heard rumors of
discs being stored undisturbed in safety-deposit boxes for 5yrs
starting to break down. Some people I know with a rather small set of
backup DVDs read the existing discs and burn a new set every 6-12mo.
This serves the purposes of verifying that you can restore from your
backup and that your media is fresh.

Heard about how "high security" locks may not be as secure as the
manufacturers claim? hackaday.com and toool.nl... the lesson from that
is to keep reviewing your backup strategy. The chances that someone
will have the means, motive and opportunity to come after your safe is
probably pretty low. Low enough that you sleep well at night.

So yeah, I think we're very much in agreement: think about what you
have to lose balanced against how much it'll cost to protect against.
And don't rest on your laurels. :)


GDB has a 'break' feature; why doesn't it have 'fix' too?
