> $99/year with no limits on data, as far as I can tell.
The limit is as much data as you have plugged in. Backblaze only backs up your currently-available data, with a 30-day grace for external disks[1]. IMO, if you have a computer with a 1TB drive, you'll probably use <1TB at all times, accounting for you not using the entire 1TB locally and your changed data probably fitting in the excess. (e.g.: 800GB used space and you change <200GB over 365 days)
