Do consider a (paid?) add-on similar to Dropbox's Extended Version History [1]. It'll at least protect against ransomware and other mishaps. It'll also be nice if you could provide an option to get alerts if a certain subset of files change. I have folders on my NAS (I know Backblaze doesn't back up servers) which are basically files from my old desktops that I'll sort through some day in the future, and which are highly unlikely to change, maybe ever.
