I'm the maintainer of the g4l project that is a disk imaging program. It is 
usually used to boot a machine from the cd with a ramdisk, and then can 
make local or network images using dd and compress. Note: this is a full disk 
or full partition images. Not a file or directory level image.

It also has an option to clone, which is a similar process to you dd option 
going from one disk to another.
