I'd like to point out https://Permanent.org/, ahem. It made the front page here a while back (not posted by me), and it's relevant here: you pay a one-time payment for permanent storage -- that's right, your stuff will stay right there even if you're "inactive for 2 years".

(Disclosure: My company does some consulting work for Permanent. When I received the notice today from Google of their storage policy change, I realized that the reason it sounded weird to me was that I'd gotten accustomed to Permanent's model.)
