This is a small tool for continually mirroring all the public repositories from one Github organisation to another, designed for backing up organisations who may take down repositories without notice (such as governments).

It also ships with a Github Actions configuration that will run the update job hourly, and a complete repository/branch scan weekly.

• Create a new organisation that will hold all of the repositories you're mirroring
• Create a Github personal access token that has access to the destination organisation
• Clone this repository to an organisation/user you control
• Go to the new repository settings in Github
• Configure three environment variables in the Secrets panel
  • USER_GITHUB_TOKEN - The personal access token you created above
  • SRC_ORG - The name of the organisation you want to mirror
  • DST_ORG - The name of the new organisation you just created
• Run the Github Action and sit back, you now have a daily-updated mirror of a Github org!

• Hard fail when upstream branches diverge and we can't update to them
• When upstream branches are force-pushed, copy our branch to branchname-diverged-$datetime and reset to the upstream branch
• Deal with a few weird Github API error cases
• Automate more of the configuration (make it possible to just fork it to an ORGNAME-mirror account and just work)
• Generate a changelog
• Generate events if repositories are removed
