I have not gotten any comments on the proposed method of creating a “Bootable Backup”. Since I am not a computer person and don’t know if what I am doing is right, I wrote to Mr. Bombich and asked him. Below is his reply:
“Only two comments:
But I think that this method is different as it does not involve copying the system volume source and does not use apple’s ASR and , as a result, it should remain bootable and backuptable after update/upgrade.
To prove the method remains “bootable and backuptable after update/upgrade”, I would need to do an update/upgrade. My problem is that I have a 10-year-old Mac, the latest OS it could support is Mohave. I am using OCLP to run 14.7.2 and 15.2. Whenever I tried update or upgrade, the mac would get stuck at the progress bar and fail. But this may be because the Mac is just too old.
My income is limited and couldn’t justify to buy a new mac for this purpose.
In the interest of satisfying curiosity, I sincerely hope that some members with a newer Mac could try this method on 14.7.2 then see if the bootable backup could be upgraded to 15.2 and remains functional after the upgrade.
“Only two comments:
- I expect that the destination will eventually not be bootable, e.g. perhaps after an update is applied to the source: If I continue to make regular backups to the destination, will it remain bootable?
- We don't rely on bootability for any part of our backup strategy, because eventually it will not be available to us: Bootable backups have been deprecated for several years”
