Yeah, the backside of the rotors seems to be where I see that type of damage the most. And it seems to be a little more common on rear rotors than on the front.

I'm not sure exactly why, but I'm guessing that the road salt splash tends to accumulate more on the backside of the rotors (and more so on the rear than the front). While the front side of the rotor is (depending on wheel design) usually a bit more exposed to get rinsed off when the vehicle is washed or driven in the rain.
