Had a problem with SuperDuper! not working. Emailed the developer and he responded at all hours, even on a national holiday! In the end, we figured out the problem.

Love the way the software works and the smart update. I like it better than CCC and feel secure knowing that ALL OF my data is safely backed up. Sorry for all the folks that have had problems getting SD! to run well.

I'm not sure there's anything else I could want from the software. I see some users don't like the interface. Maybe it could be improved but I'm not sure how to make it better or more functional.
