Two HDs, how do I copy over only the files that the other is missing?

Two hard drives. HD2 with a bunch of lossless music. HD1 with the same music plus a bunch more music that I've acquired in recent months. I want all of my collection on both drives in case one fails. Besides copying over each new file piecemeal, or deleting everything on drive 2 and just copying the entirety of drive 1, is there a more elegant way to do this?
Is there a program or method that will only copy over the files that HD2 doesn't already have?
