For an image from a SDcard to say a hardisk it makes no difference,
as long as the size is OK, and preferable back to the same card for 'restore'.

I have no idea how to do it in MS windows ..

In Linux take the sdcard, put it in your 'puter,
type
dmesg
see what device is just found
then type
dd if=dev/sd? of=cardimage.img
where ? is the card device detected, probably sdb, but always check!

and to restore
dd if=cardimage.img of=/dev/sd?

You need enough disk space.


You cannot, I repeat CANNOT backup from a raspi live system to some external
disk or vice versa that way.
The OS should not be running.

And PLS do not type the wrong device names, that may kill your PC OS.

What OS or whatever is on the card does not matter, it is just copying data.
I do this on a regular basis, and it has rescued some old cards with a lot of
stuff on it too.
For that I have a big 1 TB external USB harddisk on the PC as backup, normally
not even connected.
Magnetic media last a long long time.
