mirrored database is a real-time, redundant copy of a primary database used for high availability and disaster recovery. It is a complete backup that stays synchronized with the principal database, allowing for an immediate failover if the primary fails.
This mirroring can be set up on the database level, and modern systems often include technologies to automate the process and handle data in different formats, such as delta tables in platforms like Microsoft Fabric.
