Dave Nanian, på Shirt Pocket som gör SuperDuper om varför SuperDuper snarare är ett komplement till Time Machine än en konkurrent:
That said, though, Time Machine isn't the be-all and end-all of backup programs. In fact, given how it works, I really do think that SuperDuper! remains both relevant and necessary -- a true complement to the functionality in Time Machine.
First, as is likely obvious, Time Machine is designed to provide automatic "temporal" backup (discussed in broad terms in the post The Ninety-Nine-Per-Cent Solution many months ago). Its primary usage scenario -- and the one that most demonstrations and documentation focuses on -- is to allow quick recovery of files and data that have gone missing, etc.
[...]
What's important to note is that this isn't, and never was, what SuperDuper! was designed to do.
Our tagline, Heroic System Recovery for Mere Mortals, tries to sum up the whole idea: SuperDuper! is designed to provide excellent failover support for the all-too-common case where things fail in a pretty catastrophic way, such as when a drive fails, or your system becomes unbootable. We do this by quickly and efficiently creating a fully bootable copy of your source drive. Perhaps more importantly, recovery is near immediate, even if the original drive is completely unusable, because you can start up from your backup and continue working.
