So, I expect it to be compatible whenever Dave gets an update ready. I have not heard that there will not be an update to SuperDuper! (I use it too) for Big Sur compatibility. There are a number of applications that are not yet compatible with Big Sur.

To be more precise only the data volume can be cloned and that is not bootable and you cannot clone a data volume onto a bootable Mac OS 11 drive and still have it bootable. Mac OS 11 (Big Sur) will be rolling out very shortly and, at least at this juncture, CANNOT BE CLONED using SuperDuper, Carbon Copy Cloner or any other available product, it can only be installed. You really want soemthing like this or this to get resonable boot times.Īlso, consider this in your plans. Note too that flash drives are notoriously slow regardless of the interface. Thunderbolt 3 is twice as fast at USB 3.1 Gen 2 (also called USB 3.2) and four times faster than USB 3, which pretty well sums up the pros and cons of each. I am not holding my breath waiting for that to appear. Looking at this in total, it appears that implementing any 'cloning' ability in Big Sur may have to include installing the boot volume using the MacOS installer, or at least portions thereof. Absorb all of this and you begin to get the full picture of what this all about, how it fits together, and how, through the actions of 'firmlinks' the system can contain elements from both the data and system volumes and reaches a zenith in the boot volume in Big Sur which is essentially a 'virtual' construct'. Working with APFS Volume Groups from the Carbon Copy Cloner Knowledge Base explains the underlying APFS structures that are enabling the new OS architectures and if you scroll down to the section on Finder shenanigans with the Applications folder you will find an explanation of how and why the file count varies.īoot Volume Layouts and Layout of the Catalina Boot Volume Group (both from The Eclectic Light Company) help explain what you are seeing in Catalina as well as answering some of the questions about why there is a big cloning issue in Big Sur and this Apple Developer News article explains the rationale behind the changes in Big Sur.
