This is unix stuff, not gumstix but be helped

In general dd is a bad choice. dd makes an exact copy so cloning an exactly-the-same SD card or creating a copy that you can put back etc

tar backs up FILES so eg

mount /dev/sda2 /mnt
ls /mnt # there it all is. Then ...
tar cvjf a-name.tbz /mnt

or as somebody else posted
cd /mnt

then tar cvjf a-name-somewhere-else.tbz *
meaning tar everything HERE to a-name-somewhere-else.tbz

saves all the files in /mnt in a-name.tbz which you cab put back on another file system etc as you will
