Appreciate the info but it is way about my pay grade. I've used Mac's since 1986 and they just keep getting more and more complicated and unfortunately I keep getting older and older.

Bottom line, I guess, is that I will probably no longer be able to clone my system for backup purposes going forward. It's probably not rational but I don't want all my 'stuff' out there floating around in iCloud or any other remote service. I liked to clone my system in the unlikely occurrence my Mac crashed and that actually happened once quite a number of years ago. With the clone I was up and running with a new Mac in short order.
