As mentioned further up this page, I use Dropbox to back up my key documents to the “cloud”, so I can access them from all my devices. Well, I use BackBlaze to back up everything else securely. It provides me with unlimited online backup. Unlimited files. Unlimited file size. Unlimited speed. It will even back up all your attached external drives. Its restore function is excellent, too. You can restore multiple versions of your files up to 30 days old, accessed via download. There’s an option to have an external drive containing your files shipped to you, too.

It’s a set-and-forget solution that will work as long as there’s an Internet connection.
