I'm repeating again and again in many threads, dd looks like easy solution, but has few caveats.

one of them is nonsense to copy even 4gb, when only maybe 500 are needed.

if one wants "system" backup, use rsync. or tar | gz to .tar.gz

best option is to backup /home only. why the system ?

but if one wants dd, ok, here are the steps to shrink:

1) put "noresizesd" to cmdline.txt
2) on booted system, "btrfs fi res 4G /"
3) check "dmesg | tail" for reported fs size in bytes
4) do "fs size / 512"
5) "fdisk /dev/mmcblk0"
6) "d" and "2"
7) "n" and primary and as second
8) for start just enter, for size, put 4), enter
9) "w" enter

reboot
