NOTE: I hope this is an acceptable forum to post this in, if not, I apologize. This being the "digital age" I'm curious as to what professional recording studios back-up their data to. I mean obviously it would be a disaster if the Goo Goo Dolls (or whoever) lost all their latest sessions because they recorded at a studio that didn't have sufficient back-up and redundancy. Do studios still have 'Master Tapes'? If so, do they still use tape or do they use CD/DVDs? If they use CDs and DVDs, what brand would be the 'industry standard'?
