You can configure SBS 2003 to be a VPN (Virtual Private Network) server using Routing and remote access (RRAS) then have the clients connect to the VPN to establish an encrypted link.

This should get you going.

A little more detail on setting up your VPN:
Set up 3003 VPN server end:

Set up client end:

You will also need to forward port 1723 for PPTP traffic to your VPN SBS, using the router. At the same time you need to allow GRE traffic, protocol 47 (not port 47) to pass. This is accomplish in different ways on different routers. Basic routers have "enable PPTP pass-through", or "enable VPN pass-through" options to allow GRE. Others require more detailed commands to be entered. Good information on port forwarding on basic routers is available at (click forwarding tab at top, then your router, then PPTP):

There are a couple of "holes" in this scenario. If there is no server at the remote end, it will be a client to server connection. The connection has to be initiated by the client. I don't know how you will do that as a scheduled event. Usually for this type of configuration you would use hardware routers to create a static open VPN tunnel.
Also, do you have enough bandwidth to upload the data each night?
