You may not need every kind of rescue disc possible, but you should certainly have one from your backup program.
You typically can’t just run Macrium in Windows to do a restore because you’d be restoring on top of a running operating system. But yes, you can easily restore the whole machine. I’ll explain.
If you don’t have a rescue disc, just find another machine and make one. You don’t need to make one every single time you update the software.
