It’s a state of a virtual machine which is stored and copied at a precise time

It’s a state of a virtual machine which is stored and copied at a precise time. They offer a changelog for the virtual disk and are used to return a VM to a precise point in time when a system error failure occurs.
Primarily following records are kept by snapshot
• State: This contains the operational state of the Virtual Machine such as suspended /active.
• Data: Includes all files from the device driver, memory, and disk.
For the operational environment, the VM snapshot is an important feature as the same instance of a VM can be created numerous times. Usually, snapshots are considered to provide a rapid roll back to a point in time, particularly in development environments. Though, it should not be misguidedly viewed as a type of backup. As stand-alone snapshots cannot provide backup. Many virtualization technologies such as VMWare ; Hyper-V strongly discourages the idea of having snapshots as a means of long-term backups.
Snapshots are very useful before performing certain operational tasks such as upgrades, uninstalling components, changing the installed software etc. They are also very useful for development purposes. A VM or set of VMs can have snapshots created for “rinse and repeat” type testing to progress and authenticate code changes.
