Enter in the age of de-duplication during the backup process. As backups are performed to the same storage device, we have the potential, and neccessity, to make sure redundant data is removed. The removal of redundant data can be enormous for large companies. Vendors take the de-duplication effort to different levels, some down to the data block level. De-duplication can take place either on the client side (where the backup is coming from) or server side (where the backup is going). Obviously there will be less network traffic if the de-duplication takes place on the client side as the data being backed up won't have to travel in network.
You can take a look at how EMC is cutting down on copies through de-duplication
