> Create a backup branch and push it up to GitHub/Gitlab/etc. This backup branch will have all your work nice and safe in case you need to start over.

The way I teach programmers to do this is to make use of cheap branches and to instead work on a temporary branch, and eventually use ‘git reset --hard branchName’ to turn your original branch into a mirror of the temporary one when ready.

This is a helpful mindset to get into; you can just throw it away in a worst case.
