Carbon Copy Cloner - Users Thread - Yosemite to Mojave to Big Sur - and after

Speaking just for me - I don't like the idea. I rarely frequent the Mac Apps thread, and would have missed all this. I do monitor both Big Sur and the Monterey threads a couple times a day. My choice, Leave It Alone.

easy enough to fix - just click that "Watch" button at the top of each thread
I have temp stopped using ccc because it has not been able to make a bootable disc. Yes I know about using the option key. Still doesn't work. SD does.
What machine, what OS? Have you downloaded the latest Beta of CCC? And, yes, SD is SuperDuper.

I have 2 Valid Licenses of SuperDuper! but I have never understood, how the app works

^^^^Should work fine if you follow the steps outlined here:
I had trouble too, but by followinging these steps clones are now is a piece of cake👍.
BTW. the latest CCC Beta is 6.0.3.

I'm surprised that someone finds SD! easier to use; my experience was that you just can not do other than run it.
I went from SD! to CCC because (a.o.) SD! gave impossible figures all the time.
Nevertheless ... it's all people's work; nothing is 100% perfect.
;JOOP!
Not sure if this will help or not - FWIW - did you reformat the target drive (wipe it clean) and mke sure there was only one partition? this might help to create the first version of the clone? CCC will automatically create the 2cnd partition for the system
I do not find SD! easy to use
For me was easier CCC older versions, that's it

still new to CCC 6.02, 11.5.1
4 weeks ago I cloned my boot drive, after completion I booted and it worked fine.
Since I have a daily task that copies new/modified files onto that boot clone, and those have all been successful. And I have upgraded from 11.4 to 11.5 to 11.5.1
Today I tried booting from that clone but no success.
I did run First Aid in diskutil but no error found/corrected.
Any suggestions what might be the problem? Should I run a full clone every day? but that has to be on a "clean" disk, doesn't it? and wiping the drive every day does not make sense ...

That’s why it makes sense to just copy your data.
In order to boot from the external drive you have to install the OS from scratch.
I understood from the Bombich info that you have to repeat the full cloning after every OS update.
;JOOP!
Well, ... that was the good news.
The (more or less) bad news is that we get security- or supplemental- updates every now and then.
All for your safety of course, but still ....
I look forward to a situation where we don't have to reclone every time. If it will ever be ...
;JOOP!
Yes, absolutely correct ... I did erase and clone again and it is booting, for my current 11.5.1 ... also posting some more info below. Since this started with Big Sur, I am guessing the "reclone" is here to stay ...
Now need to ponder if I want to make this a routine with every OS update. This would probably something like monthly give or take which seems manageable. In my case creating the boot clone took ~ 25min as I'm using a SSD and currently have ~ 420GB ...
and when you click on the "?" this is additional info ...
Things you should know before relying on an external macOS Big Sur boot device
This procedure relies on Apple's proprietary APFS replication utility, which is outside of our developmental control. We welcome feedback on this functionality, but we cannot offer in-depth troubleshooting assistance for problems that Apple's replication utility encounters.- Whether the destination is bootable depends on the compatibility of your Mac, macOS, and the destination device. We cannot offer any troubleshooting assistance for the bootability of the destination device beyond the suggestions offered in our External Boot Troubleshooting kbase article.
- The destination may not remain bootable if you subsequently update the data on the backup after applying OS updates to the source.
- Apple's replication utility may cause a kernel panic while cloning to the internal storage on Apple Silicon Macs, which could prevent you from restoring your Mac's system from the backup.
- Apple Silicon Macs will not boot at all if the internal storage fails. An external bootable device will not serve as a rescue disk for that scenario.
Been searching for a solution to my recent CCC upgrade from 5 to 6. I think the last backup on my spare drive did not create a full clone. I started to get issues with an admin user and weird crashing of apps.
So I wiped and recloned my CCC backup of Big Sur 11.2.3.
The user issue was still there. So I created a new admin user and attempted to delete the old one. It sat there for ages pretending to delete it. The user name disappeared but every time I started the machine it was there as a log-in option. There was no corresponding user folder of data on the drive but the login thought it was there. I could also recreate that lost admin user like it was new but I could never delete it so it was not seen in the login.
Round and round I went for days trying to restore, wipe, clone, or Terminal out the user.
I gave up and wiped the drive entirely and now am reinstalling everything from scratch.
This will be the first time an entire mirrored clone from CCC has ever failed me.
I have never in the past used Safety Net, and just prefer, after reinstalling from new, to make a clone of that install. That way, should anything break, I can revert to a clean state machine. As for missing files or accidental deletions, I will now be using a Time machine back up for that.
The last time I used Time machine was Yosemite.
