This thread is a huge help to me as bruised user of software who has no formal IT training.
I just downloaded SuperDuper! 2.6 which I will run on Snow Leopard in the Sandbox to back up my Macintosh HD volume that will remain 10.5.8 until things sort out on 10.6.
Thanks to all of you for this wonderful forum. You're doing a great work. Best regards.
