@jws Thanks. That doesn’t sound too bad. A bit more cognitive load but what’s new?
Thoughts:
•It was the Samsung T7 Touch that got me thinking about this and it’s non-Filevault encrypting probably won’t work with this method.
•I prefer SuperDuper! to CCC, so I’ll have to look into that.
•Looking at things in-the-round, I should probably use the method in the linked article with a normal SSD (the non-touch T7?) and use a T7 Touch for a non-system backup.
