The Winclone 3 partition on the external drive is not bootable, it's a backup only as Windows is copy protected and will invalidate itself if it ran.ĭon't use CCC to clone BootCamp, it's not designed for that and won't restore to run Windows. The OS X clone on the external drive is bootable if you hold the option key down while booting the computer.

Use CCC to clone the OS X MacintoshHD to the MacintoshHD2, and use Winclone 3 (runs in OS X) to backup Windows BootCamp to WindowsBootCamp2. The first external partition formatted OS X extended journaled (MacintoshHD2) and the second one exFAT (WindowsBootcamp2) The OS X parittion is first at the top.ĭownload these two programs, Carbon Copy Cloner and Winclone 3. Use Disk Utility to format this external drive with a GUID partition table and two partitions each slightly larger than your MacintoshHD and BootCamp partitions Get another powered external drive slightly larger than your internal boot drive. You want to make a backup of both to one drive and this is what you should do. Ok, so you have OS X and Windows in BootCamp on your Retina MBP. If you're in OS X, Mac OS Extended is course the most stable since that is OS X's native drive format. It's great for Windows when Windows is the OS you're in. The second partition can then also be used to backup any other data from your Mac instead of being locked in as an NTFS partition, only good for cloning Windows from within Windows. With it, you can create backups of your NTFS drive as a disk image to the Mac formatted drive, or restore it. The reason for making the second partition also Mac OS Extended is that you never even have to leave the Mac OS to backup your Windows partition. Disk Utility can only do the full drive every time, so you have to wait for the entire drive to be cloned, every time.

Either of the latter are much preferable because once the initial full clone is complete, either paid, full version can do incremental updates which will change only what is necessary on the cloned drive to match the source. Or you can use the third party apps Carbon Copy Cloner, or SuperDuper!. The first would be for making a bootable clone of your Mac partition. I want to make a backup of my windows partition and mac partition on my macbook pro retina on to ONE external hard drive.īest then to create the backup drive partitions both as Mac OS Extended.
