As far as I know, there is no easy way to do a complete copy of a folder structure, including contents, from one SDL repository to another. You would need to create the folder structure in the destination repository, export the objects from the source repository, import them into the destination, and then re-create the publications since they cannot be exported/imported. You could write a tool to do all this via SDL API calls, but it is a nontrivial task.
