I've never had a reason to back up anything manually on my PS4 before. Now with the recent v5.5 firmware fiasco, I must learn. So with the twins being 5 and just starting to game, Ive created a profile for them and trying to teach them to go to their profile when they want to play.

But only I have an account with PSN. The way the profiles have to be set up confuses me, don't understand why I can't have a baby profile with parental setting just for it?

Then (No I have looked) are there data files for each game under each profile? That way I could cherry pick to backup.
