You could use something like Clonezilla. On the flip side, to get an
EXACT image, as root:

	# dd if=/dev/sdX of=/place/to/save/image.img bs=1M

where "/dev/sdX" is the raw device of the WHOLE SD card (NOT a partition
such as "/dev/sda3").

To put on a new, identical SD card, as root:

	# dd if=/place/to/save/image.img of=/dev/sdaX bs=1M

again where "/dev/sdX" is the raw device of the WHOLE SD card. "dd" is
your friend.

BTW, this should be virtually identical to the way you created the
bootable SD card in the beginning, not so? :-)
