@Darkphoenix @SnowshadowII @gleick The Wikipedia dumps everyone's talking about here are text-only, no images.

As a result, the files are smaller than one might expect; under 30GB. Smaller than a Windows OS install, smaller than most triple-A games. Would fit on a modern smartphone easily. My local computer store often hands out USB drives bigger than that for free.

So the data is safe enough, many copies can be made. It's the social network Wikipedia creates and is created by that's vulnerable.
