Disaster Recovery and High Availability Solutions in SQL Server

When managing a database, ensuring data availability and integrity is paramount, especially in the face of hardware failures, software bugs, or natural disasters. SQL Server offers a suite of features designed to provide high availability (HA) and disaster recovery (DR) solutions. This article delves into the technical aspects of SQL Server’s HA and DR options. These include Always On Availability Groups, Database Mirroring, Log Shipping, and Replication.
