Database Mirroring

Database mirroring is a method used to enhance the availability and safety of data stored in a database. It works by creating a real-time copy of the database on a separate server, called a mirror. When changes are made to the primary database, those updates are immediately replicated to the mirror. If the primary server experiences failure or becomes unavailable, the system can quickly switch to the mirror, ensuring continuous access and minimizing data loss. This process helps organizations maintain data integrity and availability even during hardware issues or outages.
