This is the name that appears in the Finder, where you save the disk image file before opening it.Ĭlick the Format pop-up menu, then choose an option: ”Įnter a file name for the disk image, add tags if necessary, then choose where to save it. You can then restore that disk image to another volume. For example, if a USB device or volume is 80GB with 10GB of data, the disk image will be 80 GB in size and include data and free space. With the Mac’s Disk Utility - which is found in the Utilities folder inside the Applications folder on your Mac’s drive - you can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device.
Just create an image of that drive and store it. If you want/need to keep data from a Mac, you don’t need to keep the actual hardware around. They’re convenient for incremental backups since you can make as many different images as you want.You can copy one system to a large number of identical computers, which means you don’t have to set up every computer separately or set up the whole operating system from scratch.
