Well, think about what is different about your SDCard image vs the original SDCard image you started with. Make a note of the image you used to create your SDCard, and then backup your working SDCard with rsync:
sudo rsync -av /media/<userid>/rootfs/ ~/sdcardbackup/rootfsV4.1.6/ Now when you need a new SDCard from your backup, use the same image to create a new SDCard as you did before and then restore from your backup using rsync: sudo rsync -av ~/sdcardbackup/rootfsV4.1.6/ /media/<userid>/rootfs/ This will only copy the changes you made to the original SDCard image.
