Thank you for the explicit instructions; that clears some stuff up. Snapshots are disabled. (I believe I had never selected a volume from the left sidebar in CCC. And, in case it matters, I didn’t ‘select “Volumes” then your [my] CCC destination volume’. The volumes were displayed and I simply selected a volume.)
Now that we know that, am I correct that I could follow @bva’s procedure above to copy all data and metadata, or I could use the Finder to copy all data and probably lose some metadata?
Thanks for sticking with me on this.
