See at Backblaze
Backblaze has an intuitive app that automatically backs up everything on your drive, except apps and system files, making it a breeze to use. There is no storage limit and no file-size limit, and you can back up external drives, but you won't be able to back up network drives unless you go with a business plan. There are also no peer-to-peer backups.
