I actually just used SuperDuper! this weekend to clone my (still on Catalina) hard disk and then boot from it. It's just such a peace of mind to try and see your backup working and to know I could just resume work immediately if (when) the hard disk dies. I'd consider this a major part of a sane computing experience.
