What do I need to backup my own games?

[noni]

ok, real newbie here in terms of backing up my games...saw the wisdom of backing up when I stepped on MGS2 after a marathon 6 hour FFX session, and was handing my credit card to the cashier for a replacement copy

Can anyone help with what sort of equipment (hardware and software) that i need, as well as recommendations on what to look out for while burning?

Thanks a huge bunch!!
