• I know that all of this is (supposedly) documented more fully in BOL, but the purpose of these articles is to help clarify the topics they write about. This one makes it harder to understand. The article *mentions* Copy_Only backups but it doesn't give one whit of a clue, not a hint, about what a Copy_Only backup actually IS. Yes, I can read BOL, but an article like this ought to MENTION some broad overview of what a Copy_Only backup IS and what it's intended to do, and how it differs from the other backups.

    Copy_Only is mentioned in the middle of a discussion about the problems with log backups, but how are we supposed to guess what a Copy_Only backup is good for?
