Box and Copy offer more flexibility than I really want. Other than some documents I want them to auto upload from my camera roll like Drop Box does....who does that?
try weiyun.com
or https://yun.baidu.com/
they are both chinese but offers 10TB and 2TB respectively for free.
OneDrive is what I use and that's the only thing I use it for. Once you've set it up opening the app automatically uploads any photo that hasn't already been uploaded.
Currently there's no Mac sync app for OneDrive but it's not too much trouble to access it via the web.
