Rainbow Six Vegas DVD Backup

[AZZiDO]

Anyone know how to create a backup for this game?

It doesn't neccesarily have to be able to run the game, just be able to install it.

The files on the original disc come to 4.81 GB (5,171,108,329 bytes) whereas a normal DVD can only hold 4.7GB (5,046,586,572 bytes), so how can I expect to fit all the files on?

Thanks for any help. And this is a legitimate backup, not for warez purposes btw.
