adding archival backup to SD

Yes. I do understand what you're trying to do, and I have looked at these various methods in the tools that do them. The question to my mind is: what percentage of people want this, and does that justify either adding the complexity of adding it to SuperDuper or creating (designing, writing, testing, documenting, marketing, supporting) another similar product.

Believe me, the effort involved would not be covered by 5-10 copies, even at $100 each.

Anyway, it's something that's under consideration: I am aware of the technique. Thanks!
