As a couple of you know, I just lost 1.3 TB off a 3 TB drive. I've used Carbonite for years (decades?), NO MORE!!!
It took over 37 DAYS to restore that 1.3 TB's and... once I had it all back, the 10 TB drive I had restored to broke its connector (it's basically useless now - I'm trying to decide what to do).
Carbonite wouldn't send me a disk and their download rate caps at a ridiculous 1.5 GB PER HOUR!!!
I'm now using BackBlaze. It's cheaper, has unlimited storage, AND will use as much bandwidth that you can throw at it!
Just use a NAS attached to your computer and BackBlaze will not only back up every drive IN your computer, but those attached EXTERNALLY to your computer!
