insert the original sd card, check the name of the device (usually mmcblkX or sdcX)

sudo fdisk -l

In my case the sd card is /dev/mmsbkl0. Now you have to unmount the device

sudo umount /dev/mmcblk0

Create image of the device

sudo dd if=/dev/mmcblk0 of=~/sd-card-copy.img

It will take some time ….

Once finished, insert the empty sd card. If the device is different (USB or other type of sd card reader) verify its name and be sure to unmount it:

sudo fdisk -l

sudo umount /dev/mmcblk0

Write the image to the device

sudo dd if=~/sd-card-copy.img of=/dev/mmcblk0

The write operation is much slower (~X10)
