VMware Workstation 5.5Features | Documentation | Knowledge Base | Discussion Forums
Taking a snapshot saves the current state of the virtual machine, so you can return to it at any time. Snapshots are useful when you need to revert a virtual machine repeatedly to the same state, but you don't want to create multiple virtual machines.
If you simply want to save the current state of your virtual machine temporarily, so you can continue work later from the same state, see Using Suspend and Resume.
You can take multiple snapshots of a virtual machine, to save any state you might want to return to.
Note: To take snapshots of multiple virtual machines for example, taking snapshots for all members of a team requires that you take a separate a snapshot of each team member.
Disabling Snapshots for Better Performance
VMware Workstation operates more efficiently with snapshots disabled. If you do not need snapshot functionality, disable it for better performance. See Virtual Machine Settings for Snapshots.
