Does Carbon Copy Cloner Copy the EFI Partition?

Does CCC or Super Duper also copy the EFI-Partition?
Is the Backup bootable? I once made a Backup with CCC and it was not bootable.


@Tom012,

CCC or Super Duper do not clone/copy the EFI folder, but there is nothing special about it, just mount the EFI partition on both your source and clone drives using EFI mounter or Clover Configurator and copy the EFI folder from the source to the clone using Finder .. easy peasy.

Cheers

There is a shell script to actually copies the EFI from CCC.

https://github.com/wombat94/EFIClone

  1. Create a Clone task as you normally would, defining the Source and Destination partitions.
  2. Click on the Advance Settings button, just below the Source partition.
  3. The advanced settings pane will open. If necessary scroll down until you can see the section labeled "AFTER COPYING FILES" and click on the folder icon next to "Run a Shell Script:"
  4. Use the file dialog to select EFIClone.sh from the folder where you placed it after downloading.
  5. After you have selected it, your task should look like this - with the script name "EFIClone.sh" showing next to the "Run a Shell Script:" line. If you want to you can click on the "eye" icon to see a read-only version of the script. If you need to change the script (or remove it completely) you can click on the "X" icon to deatch the script from your CCC Task.

If you dual boot with Windows, using a windows imaging program like Paragon lets you back up both EFI and Mac partitions and restore them easily. I always backup EFI that way before doing a clover update. Best thing: No need for external media at all.
 
Will this process create an EFI partition on a new clone drive?


@NZRichard,

When you format/erase a drive using the GPT partition scheme, a EFI partition will automatically be created, its part of the standard, does not matter if main system partition is HFS+, APFS or other ...

Procedure to create bootable backup :-
  • Erase/Format Target drive using Disk Utility, ensure you use GPT partition scheme, select HFS or APFS
  • Clone existing MacOS partition to Target drive using Carbon Copy Cloner or Super Duper
  • Mount Source EFI partition
  • Mount Target EFI Partition
  • Copy EFI folder form Source to Target using Finder
There really is no need to use fancy scripts or extra software to copy/backup the EFI folder, it's just very basic file/folder management that anyone who can use Finder should be able to do.

Cheers
Jay

I am interested for your solution, what's the program?
I have also dual boot(Wx + macOS) with a lot hidden parititions by macOs or Wx(incl.EFI), really a headache if mistakenly change something cannot boot up.

He said, "a windows imaging program like Paragon." The name of the program is Paragon.
 
@EddyMac thanks. Paragon is specialist on this and I wonder which program exactly. If could a very brief procedure that would be very helpful.

Hi guys , I accidentally lost EFI partition and my clone would not boot. How can I add EFI to the clone. I can access it on another Mac.

Thank you
