Recently I’ve made the switch to using Linux full-time and only have Windows 10 as a backup for certain applications. Several factors played a part in this decision, but it was mainly influenced by Windows continuously feeling sluggish despite a reinstall. Startup and shutdown times were ridiculously long, the forced Windows updates were a nightmare and the lack of customisation did not appeal to me. So I backed up my entire 256GB SSD using Macrium Reflect Free, which I highly recommend for its simplistic GUI, fast copying and great compression. (Note however that there is no Linux version available, and it stores the file in some proprietary .mrimg format).
