This discussion reminds me of when Dropbox was at ShowHN and someone was commenting on how this could be done with FTP. https://news.ycombinator.com/item?id=8863
I still haven’t purchased Dropbox. When the choice came up, it seemed important for our backups not to be made in USA. So, indeed, a very cool replacement was SSH. I still don’t know anyone who didn’t leave Dropbox after they jacked up the prices. A USB key is much cheaper (and reliable, at the rate at which Dropbox nukes accounts that they deem not compliant with whatever policy).
Funny, I don't know anyone who did.
