What is Database Mirroring?

Database mirroring is a SQL Server feature that provides high availability and disaster recovery for databases. It involves maintaining a copy of a production database (the principal database) on a separate server instance (the mirror database). Transactions are applied to both databases, ensuring that the mirror database is nearly identical to the principal. In the event of a failure of the principal server, the mirror database can be brought online quickly, minimizing downtime. It is commonly used for business continuity and data protection.
