This looks excellent. I have been meaning to set up something similar myself recently and just stumbled across this app which looks like it will do exactly what I need!
However, I am running into what appears to be an issue - the script ran through and indexed all of my repos, but it only seemed to download metadata - not the actual content of the repo. Is this intended? Or do I just have something configured incorrectly? I checked that my access token has the correct permissions and the container logs don't give any indication that anything went wrong.
Here's a couple images showing what I see in the backup data... it looks quite similar to the .git folder of my downloaded repo.
