Gary,
You can *ask* about best practice, but in this case no one can say
what's universally best, not to mention what's best for you. I still
think you got some answers and a few examples of what people are
doing.
It depends on what events do you want to protect yourself against, how

Yes. Mirroring does not make any tape backups redundant, but they do
drop to plan B in case of disaster. They remain plan A if you lose a
file or a disk and even then

Mike,
I didn't mean to be smart, sorry if it came out that way. I just wanted to
stress that everything you need to perform a DR, including hardcopy reports,
