NFL2K1 backup?Help?

I just had to buy my third NFL2K1 game. Dreamcast games scratch very easy and then don't want to work!! Does anyone know if I could make a backup of of NFL2K1? and if so how?

p.s If you think you got some skilz in 2k1 and you got online play look for SMUSHanyONE!! AND i'll put a beaten on you!!
