Overall it boils down to having enough harddisk space to do that. Besides that it is not much magic involved, IMO.
According to this report http://www.heise.de/tr/aktuell/meldung/62626 [in German] this is a regular PC equipped with 3.2 TB of disk space.
That's about as little magic as one can get :-)
