Explanation
Virtual machine snapshots capture the exact state of a VM at a specific point in time. After applying a patch and testing it, the administrator can instantly revert to the pre-patch snapshot and repeat the test as many times as needed - a process that takes seconds. This makes iterative testing fast and cost-effective. Creating a full disk image and restoring it each time is slower and more operationally complex. Creating an incremental backup of a physical PC is not designed for rapid, repeatable restoration. Imaging a patched PC replicates a post-patch state, which is the opposite of what is needed for repeated pre-patch testing.
