Yeah, there's plenty of tools to get things into cloud-based backup-oriented storage-offerings, it's just that none of them are as cost-effective as BackBlaze's unlimited offering for Windows and Macintosh. Thus, it's less the tools I'm concerned with than the ongoing financial-outlays.
I guess it depends on how much data you need to back up. For me, I can afford to restart from scratch I guess after a disaster, but I don't feel I need to save any amount approaching the free tiers of any of the cloud providers. I pay £10 per year I think for 100GB on Google Drive (which still doesn't have an official linux client).
