Hi, I'm trying to see if I can I do a derivative snapshot as a means of versioning. I wish to do this vs dd or cp as it's much faster. I do not intend to apply a snapshot back to an original volume.
So, let's say I have original_volume.img and I create a snapshot using the b option: "qemu-img create f qcow2 b original_volume.img snapshot1.img", but now I wish to create a snapshot2 from snapshot1.img. Is there a way to do this? Also, is there a way to generate 100% snapshot of the original volume (an exact replica), so that a 40G original results in a 40G snapshot? Thanks, Mike
