I am preparing the epub version of a text book for a friend, and have pointed out to him that the standard copyright notice:
'All rights reserved. No part of this book may be reprinted or reproduced or utilized in any form or by any electronic, mechanical, or other means, now known or hereafter invented, including photocopying and recording, or in any form of storage or retrieval system, without prior permission in writing from the publisher.'
is not suitable for an ebook since (amongst other things) it forbids readers to make a backup copy. He has indicated that he is happy for me to design a different copyright notice. He wants to retain copyright, does not want the book to be in the Public Domain, and does not want to use the Creative Commons copyright. I want to avoid any mention of licensing.

My initial draft is:
'All rights reserved. This ebook may not be copied except for personal backup.'

If you had the opportunity to design a copyright notice what wording would you use? What else should be added to be fair to both authors and readers? I'd be particularly interested to get comments from authors.
