Recording to 2 base stations

Wondering if anyone has tried, or knows if you can, have cameras record to 2 base stations. For example, I currently have 2 cameras and a base station. If I get 2 more cameras and another base station, could I have all 4 cameras record to both base stations?

Thinking in terms of having a back up in the event one of the base stations was stolen or damaged.

You can only record to the base station the cameras are connected to so you can connect 2 cameras to the first base station and 2 cameras to the other one.
