How to clone octopi/octoprint SD card

not really an issue, just an enquiry

I have spent some time "tuning" my setup to work they way I want it
if the SD card have dies, it'll take a while to get back to my preferred setup

so I thought best plan is to clone the card

what technology did the clever lads/lasses at OctoPi use to create their card image?

I tried WinDiskImager (I think that's the name)
it seemed to make an image slightly bigger than the original SD card!

TIA

You may look here: Cloning install from SDCard

Are you a linux person?
You could use something like this to shrink the image down and expand it later on the new sd card via raspi-config

I use rpi-clone.

thanks all
I've downloaded rpi-clone to play with this evening!
