Are you looking for disk imaging or cloning tools for MacOS? (Disk Utility isn't working well)
Hey all. For most of my backup needs I’ve used Macrium Reflect on windows which is AMAZING. First off the personal use version is free and the basic features in this version are fine for me. 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. But 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. Several people recommended the native Disk Utility in macOS to do backup/cloning and I found it to be horrible. I tested making an image of 16GB flash drive in disk utility. 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. 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. Is there a good third party app for macOS that can do what I do in windows?
I haven't touched OSX much lately, but here are some useful links:
- How to write and backup system images for an OS image and ISO files on a memory card or disk
- Creating a disk image on Mac OS X using the Dd command
- SuperDuper description page
When generating an image of a disk, you anticipate it to retain the original byte count. On macOS, Sparse Images appear full (like 16GB) but actually use only the necessary space on disk. While using Disk Utility, did you choose the Compressed option? Both SuperDuper and Carbon Copy Cloner are highly regarded in this area. Alternatively, you can run `dd` on a sparse volume, which achieves similar results to those tools. If you prefer a file-based copy rather than a byte-for-byte match, check out this guide on using sparse bundles and rsync: https://blog.fosketts.net/2015/07/22/how...sk-images/
