Seconded, heartily. The huge advantage of CCC vs. SuperDuper is that it automatically offers to create or update the Recovery partition, which is critical for many reasons. SuperDuper does not offer this vital feature during or immediately after a clone, and the developer has chosen the position that end users can do this on their own "using standard system tools" if they want after reading how to do it on their own time. This self-support and self-education is not going to be something the majority of basic users will ever do, because there's no alert or indication from SuperDuper about the importance of having a Recovery partition.I highly recommend Carbon Copy Cloner. I tried most of the others, and it is the best in its class. It is the only one that can clone APFS to APFS, HFS+ to APFS and any other combinations.
