I'm trying to understand how a judge would say that the only practical use of backups were copyright infringement, since that is completely contrary to both my experiences and what I believe to be common sense. If the answer to my confusion is that this actually was the major use case and my experiences were rare, then that's fine. Otherwise, I can't help believe this is yet another case in recent history where judges are completely backwards on technological understanding, or maybe even under influence from copyright holders.
