Is it possible to restore data from an incomplete icloud backup??

I tried to back up my iPhone before I got my new phone so I backed it up and reset the phone back to factory settings and sold it. so now i tried to restore my icloud back from onto my new phone and there is no back up available but when I go onto icloud control panel on my computer it says there is a back up but its incomplete and had 28GB of data.. Does anyone know a solution on how to access this incomplete back up?
