How to automatically backup everything to a safe location
I can only suggest Titanium Backup - https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup, since I haven't really tried any other apps.

I used to use it when I first got Android after I rooted, I used that to do a backup before installing a new ROM. Was incredible. Don't know about the scheduling though, but that wouldn't surprise me if it had it.
