M.Chapman Posted July 28, 2021 Share Posted July 28, 2021 (edited) I've always tended to have 2 backups of my Mac stuff. A Time Machine (TM) backup, and a bootable Carbon Copy Cloner (CCC) backup. I'm considering updating to Big Sur, but notice that Bootable backups are no longer recommended with Big Sur, and in particular with M1 Macs, and CCC 6 no longer makes bootable backups by default. This article from CCC gives more details. https://bombich.com/kb/ccc6/cloning-macos-system-volumes-apple-software-restore Although slightly more complex, I'm quite happy to recover a system (if needed) by installing a fresh copy of macOS from a bootable installer disk - created as per https://support.apple.com/en-gb/HT201372) and then restore my data and settings (if also needed) from my TM backup, or a non-bootable CCC clone using the migration assistant I'm a firm believer in having 2 backups so this leads me to a question - Which to use? 1 x TM backup (on site) + 1 x TM backup (off-site) or 1 x TM backup (on site) + 1 x CCC (off-site) I suppose I lean toward the second option. Two backups using differing technologies seems more fault tolerant? Also CCC backups are more accessible on other systems (Linux, Windows) than TM "bundles".
