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.
