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