How to make a bootable OS X disk backup
#
1. Make a disk clone
Open up CCC(carbon copy cloner) and make a disk clone. If you've already made a clone then it will prompt you just copy the recent files to the backup disk.
#
2. Copy/Make EFI partition
Open up terminal and use $ diskutil list command to check which disk you want to copy EFI partition from. To see EFI partition you need to mount it with CLOVER configurator first. If this is your first time disk clone you want to install multibeast. Multibeast will install EFI partition on your cloned disk. Copy the CLOVER folder from EFI partition.
#
3. Try it out
Disconnect your main disk and check if the backup disk boots up. If it doesn't, make sure you've copied EFI partition from the correct disk. Also try copying the whole EFI partition, not just CLOVER folder. If nothing works try the whole process again I guess :D.
