Because storing 240TB is expensive even locally. From https://diskprices.com/ https://diskprices.com/, if he gets a good deal of $8/tb, it's going to cost $2,000 just for the storage of his data, and getting the data onto it would require a setup that can address and power 20 drives (assuming 12TB drives), unless they use a few USB HDD Sata adapters to archive it all.
