git: pushing a branch to a remote git repository

[Micha <michf@post.tau.ac.il>]

I'm using a clone of a local git repository to backup the repository. The 
problem is that it seems that when pushing changes, only master is pushed to the 
remote repository instead of all the branches.

Is it possible to push/pull branches into an existing repository and make sure 
that a push updates everything including branches?

Thanks
