Very quickly in a few sentences, when a Snapshot is taken or created, a new child (delta) file is created linked to the parent disk, all writes are now written to this child disk (the snapshot), the parent disk, has no write lock on the file, so it can be copied, when the snapshot is deleted, it's contents are ,merged with the parent.

There are no differences in snapshots between any version of ESXi/ESX.

My EE Article should tell you all you need to know, after reading it and ALL the links

HOW TO: VMware Snapshots :- Be Patient

if you still have questions, please ask.

Minimum free space to create a snapshot or delete a snapshot, depends on how large the snapshot is, and how active your virtual machine, is, approx a snapshot grows at the rate of 1GB an hour for an idle VM, much more for a very active VM.

We allow 20% free space of the datastore size for snapshots.
