Bootable backups on macOS Big Sur
CCC can now make bootable backups of a Big Sur startup disk on Intel-based Macs. Support for System volume cloning on Apple Silicon Macs is disabled for now because Apple's APFS replication utility does not currently work on that platform. When Apple fixes that, we'll post an update to CCC that restores support for making bootable backups on Apple Silicon Macs.

CCC is a native app on Apple Silicon and is 100% compatible with Apple Silicon Macs.
CCC will automatically proceed with a Data Volume backup when backing up an APFS Volume Group on Apple Silicon Macs - that's a complete backup of your data, applications, and system settings. If you would like to make your Apple Silicon Mac backup bootable, you can install Big Sur onto the CCC Data Volume backup. Please keep in mind, however, that your CCC backup does not have to be bootable for you to be able to restore data from it.
