Your friend is clearly a hoarder. 20TB is absurd for a private collection of unimportant media. Instead of looking for ways to back up the Library of Congress, your friend could seek counseling to work through his attachment issues.

I flew without any luggage with a one-way ticket and was "randomly selected" each of the 4 checkpoints I passed through. When I bought my last set of tickets, the vendor admitted to me that the extended search is authorized right on the ticket itself. The searches were for metal. Are there no plastic projectiile weapons?
