If you think you can "hit it big", you might be able to convince a few people in your "circle" to "invest" in getting the gear. I don't think bandwidth costs all that much, since it's not expensive or difficult to get 1 gbps / 10 gbps connections for homes in many countries.
Or they could even have hacked a bunch of home / other company systems and storing the data a few GB here, and few TB there, etc.
With sufficient redundancy, it will all be accessible / usable.
Of cos I have no idea what may have happened in this case.
