The importance of disaster recovery has been known for decades and it is nowadays commonly
recognized by IT professionals. The 9/11 terrorist attack on the World Trade Center has led to
widespread awareness about the need for disaster recovery and many other business continuity concerns.
Disaster Recovery signifies a series of action that is taken to major unplanned outages to lessen the
effects. Hacker attacks, computer viruses, fire, flood, earthquake and many other natural disasters,
underground cable cuts, power failure and system administration mistakes may all result in disaster for
businesses and other organizations.

When preparing or planning your Network Recovery Plan, be sure to include details about Plan
Maintenance, Plan Exercise, Plan Location, Plan Distribution, Plan Introduction (that encompasses
purpose, applicability, scope, assumptions, and use of the plan), Network Profile (composed of network
specifications and network requirements), Plan Activation Procedures (under which falls the plan activation
team), Team Members and Responsibilities (active team members and travel to alternative location),
Recovery Procedures (restore network services, restoration procedures, original or new site restorations,
concurrent processing and plan deactivation), and last, the Appendix (Employee contact list, vendor
contact list and network diagrams.)

What are the elements of a Disaster Recovery checklist for a Network (which could either be general
network, LAN and WAN)? In general network considerations, try to prepare a DR Plan (or Disaster
Recovery Plan) and remember to take fractional types of disasters into account; graph and identify your
network devices and current network; and do not forget your network security when you encounter a
disaster – you do not want your network to be brought down by a virus.

For the LAN, be sure that DR LAN is in its perfect setup. Be aware of the LAN pipes and sizes, then, be
sure to have backups of all the files and devices of the network configuring tools.

For a WAN, there are some questions that you may want to ask yourself are: how do you compare DR
WAN network to a Production Network? Have you run checks to test the performance of the DR
network? How does the security of a DR Network differ from that of a primary network? Be sure you
are ready to answer those kinds of questions. Consider also that this is not a complete list of things to
remember in network disaster – it would be best to research thoroughly any that have been left out.
