Difference between AWS Snapshot and Volume

Question

I see that snapshot is just a backup of volume except that you can create another volume from the snapshot. I guess there would be other differences. Does anyone notice other differences which really matter?

Answer 1

After looking at the responses, I did my own research. Here is what I found. Snapshots go across regions where volumes stay in the same region as the snapshot. You can create a copy of a snapshot but you can't create a copy of a volume. In order to make a copy of a volume you have to use a snapshot. Volumes, images, instances all depend on the snapshot. Snapshot is the glue between volumes, images and instances. Please add if anyone finds other interesting facts.
