Re:Illegally downloading? (Score 1)

AFAIK, you are allowed explicitly by the fair use doctrine to make a single copy for "archival" purposes. That is to say, as long as you are only using one copy at once, keeping a backup copy made from a legally acquired original is fair and legal. Typically this is brought up in respect to software, but I'm pretty sure it applies to any other medium that conveys copyrighted content as well.
