I have been using Macrium Reflect Free for years on Windows 7 and 10. It is a really good idea to make a rescue disk or USB stick, which is easy to do from the Macrium Reflect GUI. In fact this is a must-do.
I make a backup every Saturday of my Windows system drive, and I rotate the image location among 3 different external or internal drives.
It works on workstation Windows XP or later, and Server 2003 or later.
There is no version of Macrium software that runs on Linux, although you can use the rescue disk to restore an image that contains Linux formatted partitions.
