What Is Captured by a Snapshot?
A snapshot captures the entire state of the virtual machine at the time you take the snapshot. This includes:
  • The state of all the virtual machine's disks.
  • The contents of the virtual machine's memory.
  • The virtual machine settings.
    • When you revert to the snapshot, you return all these items to the state they were in at the time you took the snapshot.
    Note: In certain special purpose configurations, you may want to exclude one or more of the virtual machine's disks from the snapshot. To exclude a disk from the snapshot, choose VM > Settings, select the drive you want to exclude, then click Advanced. On the advanced settings screen, select Independent. You have the following options for an independent disk:
  • Persistent — changes are immediately and permanently written to the disk. All changes to an independent disk in persistent mode remain, even when you revert to the snapshot.
  • Nonpersistent — changes to the disk are discarded when you power off or revert to the snapshot.
