Description: An ‘Instance Snapshot’ is a copy at a given moment of a virtual instance, capturing the complete state of the system, including its configuration, data, and running applications. This technique is fundamental in virtualization environments, where the goal is to ensure service continuity and disaster recovery. Snapshots allow system administrators to revert an instance to a previous state, facilitating change management and troubleshooting. Additionally, they are useful for software testing, as they allow experimentation without the risk of affecting the production environment. Snapshots can be created manually or scheduled, and their implementation varies depending on the virtualization technology used. Overall, snapshots are an essential tool in modern virtualization, providing flexibility and security in the management of IT resources.
