This makes me really happy. Dave has kept the great things about SuperDuper (I especially love “what’s going to happen next” - wonder why other software doesn’t do this) and upgraded its abilities.

Backup sounds simple but it has 1000 edge cases, from idiosyncratic behavior of different drives, to filesystem-specific issues. To keep on top of that while each MacOS release brings its own changes and challenges is a Herculean task.

It means that when I occasionally do a backup I can benefit from all that knowledge and hard won experience. No “it worked with the other drive but not this one, maybe it’s the cable?” type issues. Easiest purchase decision ever.
