Error 49244 during using of ASR or Disk Utility

I have a MacBook Air M1 2020. MacOS Ventura 13.0.1 When I try to make a

clone of a system disk to external drive, I always get error 49244

regardless a tool I'm using - "asr" in terminal or Disk Utility. How to

fix it?

MacBook Air 13″, macOS 13.0

That can be attributed to three things;


1 - Using Disk Utilities to make a Clone of the drive will not work - period


2 - Specific to Big Sur macOS 11,  Monterey macOS 12, Ventura macOS 13, the Operating System resides in a Sealed and Read Only Volume that can not be opened by the User. Only Apple can do this and usually does some when there is a update or when upGrading to newer versions of macOS


3 - Even the Developer of a Clone Software called Carbon Copy Cloner as mentioned the ASR functionality is a Best Effort basis

With System 1-9 it was easy to copy a bootable system: just Finder-copy the "System Folder" to another DD floppy (and AFAIR maybe command-double-click the System file to "bless" it?).


But OS X changed all that and I have used Carbon Copy Cloner since its first versions to make bootable clones also on a silicon Mac.


"CCC uses Apple's APFS replication utility, "ASR", to establish an initial bootable clone of your startup disk."
