my old site just disappeared.

I was playing with a redesign and was no where near ready to have it go live and take over my current site.  I thought i had just saved it to come back and work on it later but my old pages are gone and the new ones are live even though they are no where near done.  I don't want to recreate the wheel on everything so i really need to see the pages of my old site.  Is there any way to be able to see the old one?  is it saved anywhere?
