The best and easiest way to do full image backup and restoration is: booting with sd card,
then using the `dd` command:
backup:
dd if=/dev/mmcblk0 of=backup.img
sync
restore:
dd if=backup.img of=/dev/mmcblk0
sync
Replace '/dev/mmcblk0' with the emmc device file in your board.
There are /dev/mmcblk0 and /dev/mmcblk1 if using sd card to boot.
You can find the sd card one by running `lsblk` command.
