My sister's husband is snooping on all her texts and emails through their iCloud account. She was so outraged she wants to stop using iCloud altogether (I don't blame her. It's the mark of the beast, or at least the Hotel CA - you can check in, but you can't check out). Is there a way to directly backup her iPhone 6S to an external drive, without going through iTunes (which sends everything to the freakin Cloud!)? Can she just plug the iPhone into a drive and download her messages, email, music, etc.? Does she have to use their shared laptop as an intermediate step?
