Th best windows backup software or utility for Windows 11/10 OS?

Hi everyone, I’m kind of a newbie here and I really need some advice. I want to make a full backup of my Windows 11 laptop because it has very important personal and work data on it. I’m a bit nervous about messing something up, so I'm looking for the simplest and safest method to let me easily backup Windows 11 to an external hard drive or SSD. I don't have much experience with windows backup software, so I prefer something easy to understand and not too technical. Ideally, I just want a way to back up the whole system so I can restore everything if my laptop crashes or the drive fails. What is the easiest utility you recommend for beginners on Windows 11? Built-in tools, external hard drives, or any beginner-friendly software suggestions would be really appreciated.
