A Backshop is not somewhere you could buy, say, a back-scratcher. You will however find a large range of bread and pastries, for "Back" derives from "Backwaren", aka "bakery products". And as "shop" is a direct equivalent of der Laden, it's "der Backshop".
This word has become common in Berlin since the late 1990's; I'm not sure why, or what advantage it has over the more prosaic Bäckerei.
