A great discussion, Paul!
My biggest danger to data loss is--me. I've modified my working
procedures as much as possible and keep backups, but every once in a
while, I'll do something stupid, such as "rm -rf *", in the mistaken
assumption that the system I'm on contains a .bashrc file with "alias
rm='rm -i'" in it somewhere.
I know of no RAID setup that can save me from stupid.
