Does anyone have any idea, how to backup a large exchange DAG? And I mean really large, >100TB. Any reasonable ideas are welcome.
I'm not sure how to improve the question. No, it's not hypothetical, it's very practical. I'm not sure what more facts one needs. It's in one DAG with many (smaller) databases. Is that a bad design? Why?
Yes, one way is to put it on 100 or so tapes. One full backup. Are there any other ways? Other ides? That's why I am asking.
