using dd on a mounted filesystem

Hi all,

Is it possible to feed a mounted partition as an input to dd?
For example, say that I have a partition /dev/hda1 mounted as /. Say also that I have another partition /dev/hda2 mounted as /hda2. So, is it safe to do something such as:
"dd if=/dev/hda1 of=/hda2/image.img"?
Thanks.
Greg
