FYI -- The backblaze storage hardware is similar (at least conceptually--specifics differ greatly) to what all the big self hosted backup companies (Mozy, Carbonite, SpiderOak, etc.) do. Custom hardware and data center storage software is the minimum price of entry for the industry these days.

The issue here I think is that "unlimited" really isn't unmetered and it never really was. The industry has often seen that marketing gimmick accompanied with abundant exclusions, fine print, and far less ethical tricks like upload rate limiters, that effectively impose limits behind the scenes.
