When you're done using the disk image, you can eject it. Copy items from the disk image by dragging them to your desktop or to your folders. You can then double click this virtual drive itself to open its contents in a new Finder window. This usually looks like a white hard drive. The image mounts as a new volume on your desk top. To open a disk image, you just double click on it. They store files in a way that acts like one of these data storage devices. Disk images are a kind of virtual disk-like a CD or DVD or even a hard drive. When creating an image in Disk Utility did you try selected the `Compressed` option?īoth SuperDuper (the link above) and Carbon Copy Cloner are considered the best tools in this space.If you've ever downloaded a DMG file from a website, you've dealt with a disk image. However in macOS you can create Sparse Images, these will appear to be the full (16GB when inspecting from inside) but on disk (outside of the image) they will take up just the space that is needed. If you what to make an Image of a disk then you expect it to be `byte` for `byte` the same as the original. Not only did it take a whopping 22 minutes at 13 mb/s, it made a 16GB image even though only 2 GB is used. Is there a good third party app for macOS that can do what I do in windows? Macrium reflect in windows would have taken maybe 2 minutes at a MUCH faster output speed and it would only make an image from the data USED (2 GB), and on top of that it would compress it with a REALLY good ratio so it would have been like a 1.6 GB image done in 2 minutes instead of a 16gb image done in 23 minutes in disk utility on Mac. I tested making an image of 16GB flash drive in disk utility. Several people recommended the native Disk Utility in macOS to do backup/cloning and I found it to be horrible.
It does amazing compression ratios, its super fast, it can make its own format of images that are read/write and mount very quickly in windows.īut recently I use my 2019 MacBook Pro Touch Bar more than my pc and I’d rather not have to turn on my windows computer every time I want to clone backup my drives once a month or whatever I do. First off the personal use version is free and the basic features in this version are fine for me. For most of my backup needs I’ve used Macrium Reflect on windows which is AMAZING.
