Using snapshots
Snapshots are a point-in-time to which you can revert a virtual machine when changes made to the virtual machine after creating the snapshot should be discarded. For example, snapshots are useful when you are installing or upgrading software in a virtual machine. If the installation or upgrade goes wrong, you can easily restore to the time the last snapshot was taken, in order to get back to the state before you started the installation or upgrade. If you have verified that the installation or upgrade was successful, you should remove the snapshot, because snapshots use valuable space on your datastores and decrease the performance of your virtual machine.
