Remember that you cannot trust the size of sd cards. If you need to make a backup of a card and ensure the image will fit on a card of the same claimed size you should shrink the last partition on the device a bit before backing up. Otherwise you can end up with a damaged file system.

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? :-)
