Thanks for the recommendations! So to follow up, I went with IDrive since they backup an unlimited number of mobile devices and computers without charging extra per extra device. And they offer private key encryption, which means the key to my data is kept off their servers so only I can access my files. They give a reasonable amount of storage space at a reasonable price, and a lot of great features like Instagram and Facebook backup and a scheduler tool. The interface is easy to use, too. I recommend them to anyone looking for an affordable, secure backup service.
