You really don't comprehend do you? Bad ram, controller or power supply
could easily corrupt both hard drives before the corruption is noticed. A
corrupt OS is probably the least likely reason why a backup would also
become corrupted. Your method of backing up is good for quick backups. It is
probably the least bulletproof of any backup method. Most knowledgable users
use a similar method for quick backups and another method less often for
redundancy.

So data corruption (as opposed to OS corruption) can be caused by faulty
hardware and render useless ANY connected drive? That's a good reason to
maintain a copy of my data on disconnected media.

I suspect it is a fairly dim bulb though ... sort of like
a Christmas tree light maybe ...

Just don't raise them close to deserted areas, some people might steal them
to ride on

You are so lucky, i wish i had the need for bullet-proof backup systems. My
work has a backup system (like most should), but i probably won't be allowed
to destroy the Windows Server 2003 O/S.
