That's fine, my comment/explanation could have been clearer. I was trying to explain that there is two markets for backups/Tarsnap and trying to shoe-horn it into the GitHub comparison led to confusion. GitHub sounds like it is a SPoF for you is the only reason I'm adding this part of the comment: If you can't 'imagine' a suitable replacement, I'd try GitLab. They are similar enough I think you'll be surprised how easy it is to replace GitHub in your workflow. I'm not suggesting you actually replace GitHub, I'm just suggesting you expand your options so you have a backup plan in case GitHub disappears one day.
