John, Ron, to split hairs a bit, RAIDs and Arrays offer *redundancy* in the event of inevitable drive failures, and are not “backup”. They certainly are not “archive” either!
Ron, I for one would also LOVE to see a dedicated backup and archive forum, and I would be active in it. I’m an IT consultant with a strong Pro Video focus, and there are LOTS of smaller businesses using hard drives as archive/backup, which is a REALLY bad idea! It’s my mission to protect businesses and especially, their data/footage.
