Yes, thats the correct command. If you have expanded the file system to the max size of the SDCard the backup can take a very long time depending on the size of the card.

Code:
diskutil list
diskutil unmountDisk /dev/disk3
sudo dd if=/dev/disk3 of=/Users/Lt1user/Documents/moode.img count=6242304 bs=512
diskutil eject /dev/disk3
