How big is a snapshot by default?


So, I have been in the dark. (I attached a random pic not really of a snapshot :D)

I was under the impression that the snapshot in vmware – when a snapshot a snapshot is created will only be a few megabytes. Well I was wrong!
When a snapshot is created – the .vmsn which is the snapshot state file and stores the running state of the virtual machine – aka its RAM. So this will be = to the size of the RAM that is set for the virtual machine.
So if a virtual machine is with 16GB of RAM – then the .vmsn file which is created in a snapshot will be of that size 16GB!
Needless to say , the snapshot file which is the <vname>-Snapshot<###>.vmsn grows with the snapshot.
