Thanks Joe, ok great. My clones Super Duper take 45 min and hour, called a "smart update' - any idea why, not good as CCC?
Carbon Copy Cloner's
Full Volume Clone takes advantage of an "under the hood" Catalina utility that works with the APFS file system and without any reference to the individual files. It runs in two steps
- The source volume structure replaces the volume structure on the target drive effectively totally erasing the target drive.
- The data from the source drive is moved en masse to the target drive
It has, until very recently, been in beta, so of course I had to try it, but the current version of CCC(Version 5.1.21-b1 (6045)) has dropped the beta warning from the option. CCC still offers the conventional Copy Some Files, and Copy All Files options which work on both HFS+ and APFS volumes, copy on a file-by-file basis, and take a
lot longer.
The same utility is also available in Marcel Bresink's TinkerTool System version 6.89 (build 200610) at a much lower cost, but the user interface interface is nowhere nearly as good as CCC.
