![]() #CARBON COPY CLONER 4.0 VS SUPERDUPER SOFTWARE# I have been using CCC for many years but my understanding of it at the moment is that it cannot effectively make bootable backups with Monterey due to the 'sealed' OS system files and all it does now is backup the Data. In the event of a failure it appears that the os has to be downloaded from Apple and then the Data added from CCC. Out of interest I checked the Startup Disk in Preferences and the CCC Backup is not shown. I have never tried SuperDuper but notice that Shirt Pocket appear to suggest that the latest version of it will now create a bootable backup with Monterey. I have created a Backup using SuperDuper and it does appear in the Startup Disk in Preferences. If I understand cloning correctly, with Monterey the system files may well be backed up to an ext DD but whenever that backup is updated only the Data files will actually be updated and not the system files. My thoughts are that if I create a new SuperDuper clone each time the os is updated, and keep CCC doing scheduled backups, and I need to restore everything, could I use the SuperDuper backup to restore the System and Data files that were current at the time of the last os update and use CCC to restore the current up to date Data files. Or have I got the whole thing completely wrong?Ĭlick to expand.No, it does not need to be downloaded. If the problem is corruption in the software, the entire system can be restored from the secure enclave that Apple has created in the system. There is a section of the storage fabric in which the entire system files, as updated by Apple, are stored. On a reinstallation of the system, those files are copied from that secure enclave to create a snapshot of a bootable system. The system does checksum type error checking and then compares the checksums against what Apple thinks they should be, and if all is good, the system is booted from the snapshot. (That's a simple version, what happens is actually pretty complex. If you want to know more, start here: Booting an M1 Mac from hardware to kexts: 1 Hardware and read all three parts of the boot sequence. Once booted, the restoration from TM or migration from a cloned backup puts your stuff back where you want it. #CARBON COPY CLONER 4.0 VS SUPERDUPER DOWNLOAD#ĭepending on which is the source, you may have other things to do to clean up the installation.īut there is no longer any need to download the source, it is there in the fabric. On clones and their value, Randy said it best:įollowing some research and testing I have come to the following conclusions.
