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.
