A snapshot operation in VMware creates the following files:
.Vmdk - The flat.vmdk file contains the raw data in the base disk.
-delta.vmdk – The delta disk is represented in the format of .00000x.vmdk. It contains the difference between
the current state of the virtual disk and the state that existed at the time that the previous snapshot was taken.
.vmsd – This file is the database file for the snapshot itself which contains the snapshot information
and is the primary source of information for the snapshot manager. The entries contained in this f
ile are the snapshots and relationships between snapshots and child disks for each snapshot.
.vmsn - The .vmsn file includes the active state of the virtual machine that captures the memory state
at the point of the snapshot. This allows you to revert to a running state of the virtual machine when reverted.
If you create a snapshot without including the memory, reversion to the snapshot will be to a virtual machine that is turned off.
