Ross - that's exactly the info I was looking for. Thank you! Up until now, we were looking at having both DPM and Lagged Copies in place, but this information is a game changer for us, in a good way. You may have saved us $30,000 in our proposed deployment!
So, some followup questions- what can we do proactively to monitor for database corruption? Would an eventlog entry pop up as soon as unrepairable corruption is detected in a DB? I'd hate to have corruption in a DB occur on a saturday night, and not discover it until monday morning, and the best I'd be able to do is recover from that saturday PIT. What options are there to repopulate the DB from that PIT if I'm not using lagged copies?
