OK, "Yep". Hi, are you running 10.4.8? If so, there's a bug in the OS that's causing this, that we're hopeful will be fixed in 10.4.9 . In the meantime, try the following:

- Restart your Mac
- Quit all other applications
- Run SuperDuper! and start the backup
- Immediately Hide superDuper with Cmd+H
- Walk away and let the backup complete
- Restart your Mac

That should get it through the first run. Subsequent Smart Updates shouldn't require the workaround.

Hope that helps!
