Create an image a backup of your mac HD Drive to secure and prevent data loss. First go and open Disk Utility as we can see, I have two partitions on my di sk one named Mac HD and another HD2 and I already connected to an external drive with the partition named OS X 1010 by getting info on your backup drive you make sure that you got the correct settings to do so for instance the filesystem has to be Mac OS Extended journaled capacity has to be greater or equal to your Mac HD.
And of course writeable now we have two ways where we can create an image with your external backup disk selected go to File new and create a new blank disc save as give it a name and saving it it into your external disc already selected give a name to the image now, in size, select the desired size of your mac HD go to custom and define the exact amount you need for the purpose of this tutorial I’m only going to choose one hundred megabytes format as default Mac OS Extended journaled.
And you can let the rest settings as it is to create a new blank image and the new image was created now since I have two partitions on my disc I’m going to select the disc itself then click on restore and the source that we want to backup is exactly my Mac OS disk which going to be cloned to a destination called Mac backup the previous blank image that we created now click on restore then erase and wait until your clone disk is being created as already.
