Monster cards have a slight chance of dropping them, devimon boxes from infinty mountain can give you some try your uck in stores, the rare machine if you find yourself with a rare coin

To elaborate on the Devimon boxes, Infinite Mountain Dungeon Mega and Giga Boxes from Kuwagamon, Meramon, Monochromon, Leomon, Ogremon, and Devimon all have a chance to give 3 backup discs. Furthermore, the Super Crack of Devimon boxes from the instance dungeon behind Monochromon's spawn (Devimon only) also have a chance of giving 3 backup discs.
