Getting full ROM backup or making a ROM dump on any android device

So, you came to fully backup your device or make a ROM dump?

I have already created an article about the ways how to backup files, apps, etc. on any android device but from there, I was not able to discuss deeply how to do ROM backup or ROM dumping.
