If you're using the GoCentral, there is an area in the site editor called Site Settings, then in there you will find Site History. There are automatic backups made for different actions you take inside the editor, like deleting a section, deleting a page, or publishing, so you might look there and see if there's one you can use. It doesn't have to be published for there to be backups in Site History.
I hope you find what you're looking for!
