system backup settings

on start up of comodo backup it goes directly to the home page… the top portion shows a button for system backup… how do i set the destination of this system backup… when i click on the button it starts the backup to my d drive which is a partition created for my hp recovery… there is no room for the comodo backup on that drive… i know their has to be a way to change the destination but can not figure it out…

Go to Settings and change set a default backup location.
