Confused about backups
I have no idea which apps and programs should be automatically backed up. I no longer have room in iCloud (50GB of 50GB used). On my phone settings, it shows that more than half of the storage is backups, with a much smaller amount for messages, etc. For which apps/programs can the auto backup be turned off? I guess I just don't understand backups. Is backup like saving? I realize that I want my photos to be auto backed up so that I don't lose any of them; the same goes for contact information. So I would want "photo library" auto backed up. What about FB, podcasts, browser, books, weather channel, etc? I don't know if those apps/programs needs to be auto backed up.
