I finally got around to testing installing Big Sur on a drive with a Carbon Copy Cloner created data volume clone. Piece-of-cake ðŸ°. I cloned my data volume to an external drive using CCC then booted the Recovery Drive and installed Big Sur on the external volume. When the external drive booted after the install it came right up, even my just rearranged LaunchPad settings were just as they had been. The only way I could immediately tell the difference was the CCC warning about suspended tasks that popped up. Admittedly it took a lot less time than yesterday's recovery from Time Machine.
If we knew what it was we were doing, it wouldn't be called research, would it?
