OS X :: Copying New Files To Another Folder With Folder Action?

Is there a way to create a folder-action that accomplishes what I'm about to describe?

I have iTunes-library (like most of us do). What I would like to accomplish is to copy my library to a server on my network. Of course I can do the initial copying manually, but what I would like to do is that whenever I add content to my library, a folder action kicks in, and copies that new content to the server.

Now, I created a folder action with Automator, and it kinda works. What it does is that it looks at certain folder, gets folder-contents (subfolders included, since iTunes-library resides in subfolders), and copies them to another folder. It works, but what happens is that it copies the subfolders and their contents AND the individual files separately. I mean that if I copy a folder called XXXX which contains subfolders called ZZZZ and YYYY, which in turn contain files ABCD and 1234, it doesn't copy the folder XXXX, but it does copy the subfolders ZZZZ and YYYY and their contents. All well? Well, no, since it also copies the individual files (ABCD and 1234) to the root of the destination-folder. What I would like to copy the folders in similar way they are in the original folder.

Also, what happens when I reboot my computer? When I log back in, would the folder copy the entire folder-structure all over again? I mean, I log in, the folder-actions runs, and copies the contents of the folder. What I would like it to do is to only copy files over when new files/folders are added.
