Sync Multiple Remote Git Repositories

You have a git repository (repoA) as origin, which you only pull from. Sometimes the repoA is in the intranet and not accessible from the internet. You want to create a mirrored repository (repoB) in your local network for the convenience.

• Clone the repoA in local (repoL): git clone --mirror remote.in.intranet:repoA repoL
• cd repoL
• Add a remote repository that is pushed only: git add remote --mirror=push repoB remote.in.local.network:repoB
• git push repoB

That’s it. To sync them:

• git fetch --bare
• git push repoB

Will pull all refs, branches, and tags from repoA and push all of them to repoB.

Thanks to the stackoverflow discussion.
