Just to make sure I understand this correctly. I can create a bootable clone by entering this command from Terminal.app. (following the instructions in post #13).
sudo asr restore --erase --source / --target /Volumes/MyBackupDrive
Not from Recovery?
I'm a bit concerned about the --erase part of the command.
TIA
Why would you even consider that potential risk? Both SuperDuper! (SD) and Carbon Copy Cloner (CCC) are reliable, rock solid, have both been around for quite some time, and work flawlessly. SD is free (one can use the paid version for some extra features). If you want to use the paid version, SD costs only $27.95. CCC costs $39. Without a doubt, either one is an excellent investment.

I asked out of curiosity more than anything else. I just wanted to understand the procedure.
I can't imagine Dave (from SuperDuper) would give those instructions to someone if they are unreliable.

Dave did not give those instructions! Not sure where that got started, but it is patently false.

Also, again, either SD or CCC provides viable, reliable, rock solid options, along with having a bootable clone of your system. It's almost the same as having another machine. How could one not want that?

Dave's recommendation - verbatim:

Unfortunately, 10.15.5 has a bug i
As you know, the bug causes the "system" and "data" Catalina volumes to not be connected with firmlinks.

As a one-time fix, assuming a backup of the startup volume, please open the Terminal application and type the following

sudo asr restore --erase --source / --target

followed by a space. Drag in the backup drive volume from your Desktop, which will be "typed" for you.

For example, if the backup drive is called "SuperDuper Backup", the command will end up being

sudo asr restore --erase --source / --target /Volumes/SuperDuper\ Backup

Press Return. Enter your password when prompted, press Return, allow it to erase the volume by typing “y” and then Return, wait for completion. There will be two “percent complete” bars - both have to finish and the prompt has to come back.

Note that the low level copy that's being done will also rename the backup to the same as the source. You can rename it back on completion.

Once done, you'll have a bootable backup, and subsequent Smart Updates will be able to maintain it as expected.

Here is what indiekiduk said in post #48 above:

"No need to even use SuperDuper or CCC any more for cloning machines or upgrading disks, I suppose for incremental backups there is still a need though."

The method Dave stated is for "fixing" SuperDuper! backups when one is running OS 10.15.5. It is clearly meant to be a temporary fix. Also, CCC already had a fix out for the same bug with OS 10.15.5. With OS 10.15.6, as I clearly stated in my posts #44 and 47 above, everything is back to normal, and that "solution" by Dave is no longer applicable, nor needed.

Folks really need to keep the facts straight.
 
^^^^Where were my facts not straight?

Lou
You just relayed what Dave said, regarding the temporary "fix" for SuperDuper! only, due to the issue with OS 10.15.5. It's ndiekiduk who did not have the facts stated correctly.

Again, CCC released a version of their software to deal with the issue in OS 10.15.5, but with OS 10.15.6, all is well. In fact, CCC released another version shortly after OS 10.15.6 came out, basically to "undo" what the prior version did.

Does the free version receive any version updates? Or would you have to download a new version every time? I'm not asking about extra features, as I know you can only make clones with it.

^^^^With the paid version you have to download the new version with every update.

^^^^I wasn't mentioning cost. All I posted was that whether or not you owned the free or paid version, when an update to the program is released, you must download it from:


and reinstall. That's the way it is with most software. Nothing different or unique here.

Makes no difference regarding cost. With either version, you can download and install updates for free.
