Yes I know. I don't recall now what was out of sync, just something Calibre listed in the gui didn't match the files. I deleted it and re-imported and forgot about it and moved on. Just brought it up as an example of even though we can work on the Calibre versions, it is often best not to do so.

See my previous post for the problems with this approach, regardless of a network backend.

All good examples. Stuff I never thought about as we've never had any issues like that. Many ways to deal with them.

A backup is not a external copy that calibre is forcing you to have. Even if calibre did not exist, you would still backup your data.

Never meant to suggest Calibre was forcing me to have a backup. Just counting how many copies of a book might be on a system, which Calibre is forcing up by one now by not allowing us access to its copy. But this is all just nitpicking. Really just trying to get as much info so I can figure out which path to take for our purposes.

Thanks.
