Chapter 2. Creating, Testing, and Maintaining the DR Plan

In the previous chapter, you were introduced to the planning concepts of DR and where to start with a DR plan. This chapter introduces you to the activities around creating, testing, and maintaining an effective DR plan for your SharePoint environment. Before creating a test plan, one must have a clear understanding of what each component of your SharePoint farm is, the role it plays, and the threats that each of these components face, that could necessitate the DR plan being exercised.

Note

A SharePoint farm is a collection of SharePoint servers and SQL servers that work together to provide a set of basic SharePoint services that support a single website.

The ability of multiple servers is to work in conjunction and provide a system with its failover capabilities and load balancing. The servers can also provide readily-available backups that can scale to immense sizes. Useful for DR!

Within a farm, there are several services that run on one or more servers. These services provide basic functionality for SharePoint and regulate which services should run on which servers, in an effort to manage the impact of a failure on the overall farm architecture and performance.

There are occasions when multiple SharePoint farms make sense. An enterprise might have a quality assurance (QA) farm and a production farm. Geographically dispersed enterprises might have a farm in Europe, one in the Asia-Pacific region, and another in North America.

In this chapter, we will cover the following topics:

  • How to identify the components of your SharePoint environment
  • How to identify threats to your SharePoint environment
  • How to create an effective DR plan
  • How to test your DR plan
  • How to maintain your DR plan
