I wouldn't know, but is that the question? Someone said it was not legal in the UK to make a backup copy, therefore I asked if someone makes a backup they are breaking the law?

Prosecuted or not wasn't the question. If you're just asking if you are likely to go to jail for having a copy or 10 copies, almost certainly you wont be no matter where you live or what you have a copy of.

The main question is not about personal guilt but about funding the creative industries under the present system of private ownership.

For example the BBC in the UK has no problem because everyone with a TV has to pay a fee, then everyone has the product available.

If someone produces a creative work and it is copied and put all over the Internet for free the guy can't make a living or make the next work.

Remember that some of these creative works cost millions and employ whole industries.

If you want films, music etc for free then the state will have to raise massive amounts in levies or taxes to fund the creative industries.

You're talking about distribution of someone elses work rather than a copy for oneself of a work one already owns.

IMHO distribution is where piracy is, not in simple copies laying dormant.
