Copying Files Using SuperDuper!
SuperDuper! has an option to repair permissions on the source volume before copying. Normally this shouldn’t take 1 hour, unless maybe you’ve never run a permissions repair in the last years and the permissions are totally screwed.

I would try this:


Do the permissions repair with Apple’s Disk Utility app.
Start SD, click on the Options… button, then, under the General tab, deselect the option Before copy … Repair permissions on &lt;source volume&gt;.
Start copying.
