It is the year 2020 and replicating APFS containers still sucks. One would expect it would be a simple copy and paste in the Disk Utility app but this is still far from reality.

Last year I wrote how I managed to clone my macOS system under Catalina. The main trick was to create a DMG file with multiple volumes, mount it on target machine and drop to command-line to do asr restore from synthetised disk while avoiding possible pitfalls.

The good news is that Apple devs definitely worked on improving this under Big Sur and added some documentation (see man asr). But I didn't understand it fully on first read. Maybe someone could explain how is this supposed to work?
