SQL 2014 Admin, Part 5: Disaster Recovery and Backups
with expert Chris Bell
SQL Server offers a variety of High Availability and Disaster recovery options. The biggest change from previous versions before SQL Server 2012 is the introduction of AlwaysOn. In this course you will look at how AlwaysOn integrates high-availability and disaster recovery into a total solution. You will see how AlwaysOn is based on Windows Failover Clusters to protect the entire Instance, while Availability groups provide options to improve database availability and resource use. Then you’ll see the cover log shipping as well as mirroring and replication, which are still useful in some scenarios for disaster recovery. You will see each of these, and even configure separate log shipping, mirroring and transactional replication. Next you will see the various recovery models SQL supports and you will see the various backup scopes and types available. You will look into how these all work together to allow you to create a complete disaster recovery strategy. You will also see how having proper backups allow us to perform actions such as restoring a database to a point in time. You will even see a corrupted page fixed by referencing a proper backup all while keeping the database online to users.Course Outline
