While it doesn't support Linux, Backblaze is cloud storage and it's $70/yr for unlimited storage. To me, that's not a rip off for very secure off site back up. I backup my Mac locally to an external drive with Time Machine, many things (Photos, Mail, etc) are also in iCloud, and I use Backblaze.
If you only use local external drives, get more than one, and rotate them off site. All it takes is a fire or break-in and your computer and external backup drive could be gone. If you at least have a drive off site, there's a much higher chance that you'll be ok.
