Thankyou TR-47, for the US law. British law does not allow for copying for back-ups, Australian law does not either. That isn't to say acceptable use has been prosecuted here, however it is illegal to make back-ups of CD's (even onto MP3 players) and DVD's. In Australia you are allowed to make a back-up copy of software. I can't believe so many people think it's their legal right to make back-ups, when it is actually illegal. With that said, I can buy a software program which employees a copy-protection system, such as SafeDisc, and using my CD burner create a CD-R copy copying the safe-disc data (which is not really data, but we'll call it that anyway) so that my CD-R behaves in the same way as the original CD; and that is not illegal.
