Basically, the title question.

I'm rethinking my entire data backup routine, considering using Git to start tracking much/most (all?) of my assorted projects' histories. In most cases, it makes sense; but with my Calibre library, I'm not sure.

Has anyone tried this?

More particularly, if I do it ... what-all should be included in the .ignore file? Should I try to maintain a version history of the metadata.db file (an SQLite db file)? What about the ".calnotes" and ".caltrash" folders?

Thanks.
