I am running two HP WHS servers in my home office.  One is on a wireless N network for all the laptops and one is on the ethernet for the desk tops.  I can access both servers from several of my computers and have been manually backing up critical data from one WHS to the other, but it would be great if I could set up certain folders on the WHS servers to automatically back themselves up on the other server.  Or better keep the folders syncronized.  But since they are not on the same leg of the same network they dont see each other.  In fact, both the ethernet hub and the wireless hub are connected to the same router and I can in fact see all my computers from any other computer on either network, the fact that the two WHS servers will not see anything not on their particular leg is causing the problem.

 Is there a way I can get them to talk with each other without having to move data manually?
