Yes, some paid ones that encrypt the data and have been in business for many years. They're not publicly listed in the stock market, and so they don't have to put up with the self-destructing demands of shareholders
Interesting, you're certainly more brave than me :) One of the places I used for backups been around for 2 decades, I still wouldn't trust them enough to store my only copy of something.
Sufficiently different that you wouldn't backup your data at more locations? I don't think there is a single provider I'd trust that much, at least for data I really need to be still exist while I'm alive.
