Copying folder (with sub folders and files) to dropbox....

Hi guys, I DJ for a living and have a lot of files I like to keep backed up. Inside my "Music" folder I have a folder called "Audio Music Only".... I currently manually copy these into a folder with my dropbox with same structure names and layout. The folder is selected as online only. Is there a way I can use hazel to do this automatically for me without breaking my dropbox and keeping the folder as online only??
Thank you.
Thank you.
