A summary of the known benefits and current limitations of Time Machine backups to APFS, with links to more detailed accounts.
Until Big Sur started backing up to snapshots on APFS, there was little interest in being able to copy snapshots. Now we realise that we can’t.
Have you checked how much free space is on your startup volume after the last update? Do you wonder where it has all gone?
Looking at what’s involved in updating Big Sur’s new Sealed System Volume shows what’s necessary for successful cloning.
