USB BACKUP FOR MAC SOFTWARE
The Snow Leopard disk I used was not write-protected, but some Apple software disks do have copyright protection. The Snow Leopard recovery may be restricted from booting, though, if your computer came with Lion or Mountain Lion as those computers now have a built-in Internet Recovery feature.

Any bootable drives connected to the Mac should appear with their icons. Hold the Option key and push the power button to boot the computer. Insert the drive and power down the computer. Since this example was a backup of OS X, it should be tested to confirm that the computer can be booted from it. Once Disk Utility has written the disk image to the USB, you may eject the drive by dragging it to the Trash. If prompted, let it scan the USB and then click Restore again after it has completed the scan. This process-versus simply dragging-and-dropping the disk image to the USB drive-will make the OS X backup bootable when powering on the computer.ĭisk Utility may ask to scan your destination USB before allowing the Restore process to continue. Disk Utility will write the disk image to the USB. The previously unavailable Restore button should then become available click it, and you will be prompted to input your password. Next, select and drag your newly-formatted USB drive from the left-side listing to the destination input field. When writing the disk image to a USB, choose the source from the left-side menu first, before choosing the destination, or you may get an error. The disk image should be automatically placed in the Source box. Select the Disk Image you made in the left-side drive listing of Disk Utility, and then click the Restore tab in the main pane.

Once it's formatted correctly, it's time to merge the disk image to the USB. If you choose the destination first, you may get a "Resource is Busy" error. It's important to select the disk image first (on the left-side menu) before selecting the destination. This is important because the file structure of the USB needs to be Mac-friendly. If your drive is not already formatted as OS Extended (Journaled), you will need to select the drive on the left, then click the Erase tab in the main pane to do so. It will mount in the left-side listing of drives as your system disk did earlier. To achieve this, we'll use a different Disk Utility function.

Once complete, you will have a mountable DMG file of your system disk. This will take up to an hour depending on the size of the disk and the speed of your disk drive. I name mine "Snow Leopard Install" since the default "Mac OS X Install DVD" could apply to any OS X version. Disk Utility will create a digital clone of your system disk in the Apple disk image format (DMG) that will then be used to make the USB.Ĭhoose where you want to save the disk image and what you want to name it. Select File > New > Disk Image from (Your System Disk Name) to rip the disk to your computer.Īfter choosing a save location, leave the Image Format as Compressed and click Save to begin ripping the system disk to your hard drive.

Open Disk Utility and ensure the disk has mounted by finding it in the drive listing on the left side of the app. Insert the system disk you wish to backup into your SuperDrive or-if using a newer Mac without a one-an external disk drive. For this tutorial, I'll be creating a USB backup of OS X 10.6 Snow Leopard. You won't need any special software to digitize your Mac disks, just the versatile app Disk Utility.

So what can be done with them now? Read on to learn how to extend the life of your system disks by moving them to a USB drive. The problem is that many people still have software on disks: older versions of OS X, iLife, or iWork.
