Ed, I really don't see your point - do I need a secret decoder ring or something? The website you sent is talking about DR - we are talking about "IN SYSTEM REPLICATION!!!"
Is an instant backup copy instant - well if you can use it instantly it must be. Will the pointer based copy survive a disk failure or two - damn right it well. It will survive power failure, cache board failure, FC-AL path failure, Microprocessor failures, Host Channel failures and myriad other failures. Can you use it to make off-site back-ups - yeah sure, that's probably what 30-50% of instant copies get used for. Can you create instant copies in off-site vaults - of course not. The copy of the data has to exist there. That's called Remote Copy and it's not instant. Can you create instant copies of Remote Copied data - sure thing. That's what Storage based Consistency Groups are for. I haven't missed the point 'cause I'm sticking with the topic. If you want to talk DR then start another thread. The website you referenced does raise points about protection against virus. We have many sites that are using instant split technology to mitigate risk against problems such as virus by snapping their core business data at regular intervals. Some shops every hour, and some shops every eight hours and some shops somewhere in between, The point is the "INSTANT COPY" creates a recovery point instantly!
