I’ve got a NAS backed up to Backblaze. It’s a nice setup. I can quickly recover from local data loss, or replace a RAID disk when needed, but if the NAS gets hit by a bus then I still haven’t lost everything.
That is a nice setup since it minimizes recovery time to nothing. I'm guessing you're using their B2?
I've had 2 drive failures since using BB so it's been worthwhile. But their Download software is pretty dreadful if you have large amount of files. I may try their ship-drive option next time.
Tracking their stock price, they are operating pretty lean, so I don't fault them for having crappy software.
