Git web workflow with dev, stage and live site

Question

I'm a little bit confused about the workflows i've found. Is it right to have a bare repo, a stage repo , a live repo and a stage repo ? Isn't it really large for big projects ? I mean, so the space is four times bigger ...

Or what else can i do ? one bare repo, which copies the files ?

You probably want to use branches. http://progit.org/book/ch3-1.html
