How can I mirror a directory structure with all repositories and branches?

I can imagine various degrees of sophisticationto this,
but a basic system that works for me as a mirror is to
rsync the tree once; if you're worried you've caught 
something in an inconsistent state because stuff is in
flight you can wait for a quiet moment, repeat the rsync,
etc.
