The state of a snapshot is stored in -Snapshot.vmsn. It keeps track of all the snapshots in a metafile called. If a snapshot is created of a VM, vSphere basically freezes the original files by making them read-only and creates writeable delta files in which changes are kept. Quiescing temporarily freezes running processes and is not needed if a snapshot is created including the VMs RAM VMware Tools is used to quiesce the file system.

Without this option enabled, the VM would be in a crash consistent state in which all RAM content is lost This saves the content of the RAM into the snapshot so you can roll back to the exact running state of the VM.

You can choose to include the virtual machine’s RAM in the snapshot.
