Hey guy... I love KiXtart but for your purposes I really think the utility named RoboCopy from Microsoft is really the best tool for this. Yes you could do it via scripting alone, but please take a look at RoboCopy which can automatically do this for you in a much more secure and predictable manner with a ton of options too if wanted.

Download the Windows Server 2003 Resource Kit Tools and install or extract RoboCopy and read the docs on it. I think you'll see how easy and well suited it is for this task.
