Chapter 10 - Fault Management and Disaster Recovery

Abstract

This chapter examines the concepts storage systems—sites that can be used if the primary site is destroyed or rendered useless—as well as the way to implement layers of protection to help one to keep the systems up to achieve whatever the desired uptime is. DRPs are also briefly described in the chapter. A disaster recovery plan is a set of documents used to identify potential threats and outline the procedures that are necessary to deal with different types of threats, disasters, and anything else not of the norm and clearly defined with action in the plan. When creating a disaster recovery plan, administrators should try to identify all the different types of threats that may affect the company. Once the administrator has determined what disasters their company could face, they can then create procedures to minimize the risk of such disasters. The chapter also discusses the importance of documenting the network. In an emergency, having an up-to-date and accurate set of documentation is very important.
