The backup procedure for Big Sur is the same as for Catalina. There is one weird thing to note about Big Sur, however:Hey guys,
Is the Fully Bootable Backup Procedure for BIG SUR identical to the Catalina version as stated in the Mini Guide or is there some changes to be aware of? I searched but could not find anything related.
Trying it ATM. Cant break anything I guess.
- The first backup of Big Sur uses Apple's "APFS Replication" tool to duplicate both the System and User volumes.
- The second and all subsequent backups will only clone the User volume.
- So if the first backup was done with Big Sur 11.3, for example, and you make another backup after installing Big Sur 11.4, the System volume on the backup disk will still be 11.3.
- If you would like to backup 11.4 to the same backup disk, it will be necessary to erase the backup disk in Disk Utility and then run CCC again.
Update: Modified the Carbon Copy Cloner guide:
