I don't know that everyone is misunderstanding, but I did make a blunder with my "Right". You are correct that the snap restore should have no reason to revert to point 1. The snapshot at point 4 would also be certain to commit data as well as points 1 and 5. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
