Snapshot

A snapshot is like a photograph of a computer system or data at a specific moment in time. It captures the exact state of files, settings, and data, allowing you to preserve that moment for future reference or recovery. If changes or errors occur later, you can restore the system to that snapshot, effectively rolling back to the saved state. Snapshots are commonly used in data management and virtualization to ensure data integrity, quick recovery, and easy backup without interrupting ongoing work.
