SuperDuper! users - question

SuperDuper! users, I have a question for you. OK, two questions, really...

1) I looked through their website but couldn't find the answer to this question. Can SuperDuper! clone a Time Machine volume and have it function properly? Will it resolve all the hard links and other file complexities Time Machine requires?

2) And if it can, does it have to be a fresh erase/backup each time, or will the incremental backup (just copy/erase of changed files only) be sufficient to render a functional clone of a Time Machine volume.

Bottom line is I'm looking to make a clone of a large Time Machine volume and I'm trying to find the best way to do it. Doing a RAID 1 Mirror would require a destructive reformat (I believe), so I'd like to avoid that if possible.
