I wouldn't be surprised to see them buy up a company like Backblaze. It seems like a reasonable fit; Dropbox is already moving from document sync to 'all your stuff' sync. Adding straight-up backup would be a logical next step, and Backblaze has a huge amount of experience designing, building, and managing massive storage infrastructure. The biggest difference with Backblaze would seem to be that their service can easily assume minimal reads; besides the backup index, the vast majority of their disk usage is probably one-time writes, plus the occasional massive bulk read.
