About Messiah 2

Does it work if you use a backup???
I mean when I used my backup of diablo it worked even though it was a backup(I had the original and didn;t sell or lend it to any of my friend) So my cd-key doesn't exist in the internet so I can play on the battle-net
Could you do that in ps2?? or does it reject it because it is a backup
