    #Synchronize all changes (incl new branches and tags) from repo A to repo B, where B is a bare repo.
    #B must be an bare clone of A (initial setup)

    #There are probably more optimized ways to do this. the advantage of this method is that no branch is deleted from the backup repo
    #so the source repo is not 100% trusted
