Creating a mirror of a repo

This lets you have an exact same copy of a repo on your account, starting from a blank repo, ending with the exact same commits, branches...

First create a blank repo on Github or Gitlab or any other.

Creating Mirror

git clone --mirror https://gitlab.com/someone/repo.git
cd repo.git
git remote add gitlab https://gitlab.com/you/repo.git
git push --mirror gitlab

Updating mirror

Make sure to have mirror repo not normal repo, if you are not sure just delete your local repo and redo first step

cd repo.git
git fetch origin
git push --mirror gitlab
