Flashback Mechanism

A flashback mechanism in computing is like a safety snapshot of a system’s state taken at a specific point in time. If a fault or error occurs later, the system can quickly revert to this saved state, restoring previous data and configuration without needing a full restart. This process is useful for recovery and debugging, as it allows systems to "undo" recent changes and return to a stable condition. Think of it as a virtual "undo button" that helps maintain system stability and minimize data loss during errors or crashes.
