I have written a program that will do this. You can download it at http://www.robotbackerupper.com. The free demo version will allow you to test it on one project with one robot.
In the demo mode, it's semi automatic since you will still need to respond to the registration nag screen, but it should demonstrate its abilities.
If you try it, you will want to delete all the example projects and robots and add just one project and the robot you want to test it on.
Then right click the project for the properties and click the auto backup link. It will add a auto backup to the Windows Task Scheduler where you can customize the time and frequency.
The manual that comes with the software will give better details.
Hope this helps,
