Help me back up my iTunes to my external hard drive

Help me back up my iTunes to my external hard drive. But only the new ones....
I feel like a tool for asking this because this is something I SHOULD know how to do but am drawing a blank and my google-fu has failed me.
Basically I keep my iTunes library on my laptop and occasionally (every month or so) do a backup of my entire iTunes library to my external harddrive in case my laptop dies (again). But the problem is I have a huge (~65 gigs) library and doing a full copy is about the stupidest idea I have ever had. All I want to do is have the files that aren't already there or that have changed somehow be pushed over.
and before you say "Just sort by 'date modified' and just copy those over", my library is organized by iTunes into folders so that doesn't work.
anyone know of a free app that will look at two folders and sync them?

I meant to include a link that wasn't a reference manual, dammit.

rsync -avP ~/Music/itunes/ /Volumes/$volume_name/(or its windows equivalent...)

(oops, that should probably be 'rsync -avP ~/Music/itunes /Volumes/$volume_name/'...)

Not sure if you are on Windows or Mac - but if Windows: SyncToy from Microsoft is free, pretty easy to use and does the job. Here is an overview on how to use it.
Now I realize this is the second time this week I have reccomended a Microsoft tool, I am not a shill, honest!

CarbonCopyCloner does incremental backups, which is what you want. You can set it up to run automatically at a regularly scheduled time.

I like "Sync Two Folders" - super easy drag'n'drop interface, good options for controlling what's going where. PC & Mac, free.

As others have said, rsync is the way to do that. You may want to consider adding a "--delete" switch to that, too, to delete files on your backup that you don't have in your library anymore (particularly useful with podcasts). My "backup-music" script looks like this:
#!/bin/sh
rsync -avPx --delete /Volumes/second/Music /Volumes/Music\ Backup
(I have my $HOME/Music symlinked to the second hard drive in my MBP, creatively named "second").
The reason for using rsync (or Microsoft's robocopy) is that the tools are smart enough to have a look around before copying, skipping files that are already on the target.
