snapshot of instance with bootable volume

I have launched instance with bootable volume with 200GB. When I tried to create snapshot of the instance, it created volume snapshot of 200GB in cinder volumes and instance shopshot of 0KB in images.

question 1. does it creates only volume snapshot for bootable volume? question 2. Actually I might have saved only data in KBs along with OS which might have occupied upto 4GB. Is there any way to compress volume snapshot so that size of snapshot becomes around 5GB?

Thanks in Advance...
