Software, firmware, and systems are described herein that create and use a non-production copy of a virtual machine for reverting or restoring the virtual machine. The virtual machine is associated with an external storage device via a logical mapping. A snapshot is taken of a virtual disk associated with the virtual machine to create a snapshot copy of the virtual disk. A snapshot is taken of at least a portion of the mapped external storage device to create a snapshot copy of the mapped external storage device. The snapshot copy of the virtual disk is associated with the snapshot copy of the mapped external storage device. The snapshot copies can then be used to either revert or restore the virtual machine.
