not that I know of. the save encryption keys have been found iirc, so it may only be a matter of time. I'd suggest not using the games you own as backup though. I also made a backup of my games in hopes of selling my original discs, but I could only get $50 total for four games so it's not worth it. I don't think ps4 games go for very much used anyway. there's a way I discovered to get your saves back, but that's only reverting back from a backup. it involves creating a new save (one for each actual save you had), restoring your saved games, then loading each and saving immediately to update the save database.
