Explanation

VM Snapshot captures the state and data of a running virtual machine at a specific point in time. The VM state includes VM files, such as BIOS, network configuration, and its power state (powered-on, powered-off, or suspended). The VM data includes all the files that make up the VM, including virtual disks and memory. A VM Snapshot uses a separate delta file to record all the changes to the virtual disk since the snapshot session is activated. Snapshots are useful when a VM needs to be reverted to the previous state in the event of logical corruptions.
