Disaster Recovery Tips for Business Computer Networks | Recovery Plan
Businesses disasters are usually classified in three categories: natural, such as hurricanes and earthquakes; technological failures; and human, either on purpose or by accident. But no matter what causes a disaster, the need to recovery and get a business back up and running is paramount. Disaster recovery and business continuity today are often thought of in terms of recovery point objectives (RPO) and recovery time objectives (RTO). In other words, how much data is a company willing to lose if its network goes down. For example, a company that continuously replicates all backups to separate data centers that are actively up and running 24/7 has created an architecture with a tight RPO and RTO. A business that allows data to be replicated off-premise asynchronously or backed-up only to tape, expects it will lose some of the data being transmitted at the time of failure and assumes it will take longer to restore systems. As recent events such as Hurricane Sandy have shown, not only can catastrophic events devastate a natural environment, but they can leave a company’s IT infrastructure in ruins as well. That is why it is extremely critical for a business to initiate or enhance on a comprehensive disaster recovery plan (DRP) to protect its business and the livelihoods of employees in the event of a disaster.
1. Focus on prevention
Assess your risks and potential business impacts to determine ways you can minimize the potential for disasters in advance. Conduct regular audits and system checks of your fire prevention and safety systems.
2. Disaster Recovery Plan Needed
The Disaster Recovery plan needs to represent all functional areas within IT prior to, during, and after a disaster. It needs to include applications, networks, servers & storage. Contingencies, such as “what-if” scenarios should be considered as part of planning process. Decisions need to be made regarding levels of disruption that will constitute a disaster, downtime and loss tolerances.
As an example, a typical Disaster Recovery Plan (DRP) might include the following:
- Information Technology Statement of Intent -- This sets the stage and direction for the plan.
- Policy Statement -- Very important to include an approved statement of policy regarding the provision of disaster recovery services.
- Objectives -- Main goals of the plan.
- Key Personnel Contact Information -- Very important to have key contact data near the front of the plan. It's the information most likely to be used right away, and should be easy to locate.
- Plan Overview -- Describes basic aspects of the plan, such as updating.
- Emergency Response -- Describes what needs to be done immediately following the onset of an incident.
- Disaster Recovery Team -- Members and contact information of the DR team.
- Emergency Alert, Escalation and DRP Activation -- Steps to take through the early phase of the incident, leading to activation of the DR plan.
- Media -- Tips for dealing with the media.
- Insurance -- Summarizes the insurance coverage associated with the IT environment and any other relevant policies.
- Financial and Legal Issues -- Actions to take for dealing with financial and legal issues.
- DRP Exercising -- Underscores the importance of DR plan exercising.
- Appendix A -- Technology Disaster Recovery Plan Templates -- Sample templates for a variety of technology recoveries; useful to have technical documentation available from select vendors.
- Appendix B -- Suggested Forms -- Ready-to-use forms that will help facilitate the plan completion.
