I know this is controversial in light of their recent breach, but I use Dropbox in conjunction with a symlink into my docs folder. I don't have photos or videos, and my documents easily fit into Dropbox (I also have a lot of bonus space, from Dropquests, job fairs, and referrals). Everything automatically backs up, is accessible from any device, has revision history, and won't get destroyed if my house burns down.
