I've been using spideroak and like it - discovered it because it used to come in the opensuse repository and I was looking for a backup solution (not necessarily cloud based).

They're more expensive than most, but your stuff is encrypted on the cloud. You could still be compromised via a brute force password attack probably, so the original PICNIC problem remains a weak point.

Me, I do my serious backing up to a local NAS. Want my data? You're going to have to make it past my dog, and odds are against you.
