How to Copy a working ( volumio) image

My Setup runs on hardware PiZero2W, AudioAmpShim3WMono, DisplayHatMini. Software Volumio v3.233 and PirateAudio v0.0.6. I am completely happy with the setup. I would like to make a duplicate backup copy of this image. How can I do it ? On a windows PC ? or on a Pi3 running latest buster using copy from SD1 to SD2. Please be aware I am not very skilled in neither Windows nor Linux command structures.
