Options

Ato export a VMDK file to a backup location
Bto restore a VM memory state when its physical host crashes
Cto revert a VM to a prior state after a failed patch

Explanation

The snapshot feature is most useful when you want to preserve the state of the virtual machine so you can return to the same state repeatedly. To simply save the current state of your virtual machine, then pick up work later with the virtual machine in the same state it was when you stopped, suspend the virtual machine. For details, see Using Suspend and Resume. You can take a snapshot of a virtual machine at any time and revert to that snapshot at any time. You can take a snapshot while a virtual machine is powered on, powered off or suspended. A snapshot preserves the virtual machine just as it was when you took the snapshot - the state of the data on all the virtual machine's disks and whether the virtual machine was powered on, powered off or suspended.
