IT Disaster Recovery Planning For Dummies®

Chapter 7. Planning System and Network Recovery

Although disaster recovery planning is all about recovering critical business functions, data, and the associated applications, application recovery can't exist or operate without support from the systems they reside on and the networks that enable communication to everything else in your application ecosystem.

DR planning, in large part, is about prevention—not preventing disastrous events, but preventing the crippling aftermath of a disaster. In the context of systems and networks, this prevention involves building consistent, resilient servers and networks that are flexible and can accommodate the processing needs for the applications they support.

In this chapter, you can figure out what you need to build and maintain the server and network infrastructure that your DR needs require. Every business is different in so many ways; so, rather than just give you the answers (which would make this book far too long), I give you everything you need to think about so that you can establish the best possible recovery plan for your critical applications and processes.

Systems' resilience is the key to recoverability in the face of disaster. ...
