Hi,
I couldn't find anything like that - but the single
MusicBeeLibrary.bak
just saved me a fair bit of issues that would have been very time consuming to fix. By relying on this, I notice like there's only 1 file of this - so I was lucky I noticed the issue early enough...
So as a question if it exists (?) or if not - would be great if this could be moved to the wishlist forum (?):
I'd love to have an option to keep the last 5 - 10 versions of the MusicBeeLibrary.bak file ... i.e. even better if the time incremental intervals of the kept backup were configurable (i.e. keep either daily, weekly or monthly backups).
Just a thought

Churs.
