Dave Nanian, of Shirt Pocket Software recently announced that his well-respected backup utility, SuperDuper, is good-to-go on Catalina. I always appreciate Dave’s blog posts concerning updates. He has a new post concerning this update and it helps to get the perspective from someone working with the file system updates and Dave always functions as the canary in a coal mine.
With Catalina, your drive is divided into two separate volumes, a system volume and a data volume. These changes were made for security reasons, but created a ton of work for guys like Dave Nanian. Reading about how much work he put into this new version validates my purchase of his app.
If If you don’t have a way to mirror your drive (you should!), my SuperDuper recommendation remains in effect.
