Explanation
A snapshot is a feature that can be used in hypervisors to restore to a previous version. A snapshot is a point-in-time copy of a virtual machine (VM) that captures the state and data of the VM at a specific moment.
A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the VM after the snapshot was taken. A snapshot can be used to restore the VM to its previous state in case of data loss or corruption.
