idefrag and superduper!
If I defrag a drive using iDefrag will those changes then be carried over to a cloned drive using smart update? In practice I don't know how much difference it really makes to the performance of OS X but I thought it was worth a try. Since it can take many hours to completely defrag a drive I wanted to know in advance how superduper! will work in this case.

Defragmentation changes the file layout, not the files themselves. Since the files aren't changed, the backup won't be changed either...

Thanks Dave, would a future version of SuperDuper! include this option to change the layout or is it just not worth bothering about?

No. We copy file-by-file, not block-by-block at a low level... that's not likely to change. After all, that's what iDefrag is for.
