SEC 420 Disaster Recovery & Business Continuity overview

Disaster Recovery vs Business Continuity

Disaster recovery includes all of the steps involved in planning and adapting to potential disasters. The plans include minimizing the impact of the disaster and restoring systems and operations back to how they were before the disaster. Business continuity involves making sure that an organization can still function during and after the effects of the disaster are felt (Roseanne, 2011).

Business continuity must also factor in a separate set of costs. Redundancy and replication are an important part of continuity. For example, for continuity you don’t just buy one firewall, you buy two. You would need the other one for failover or quick replacement. There would be the cost of setting both of those up. You wouldn’t buy one server, you would buy two, and then also the cost of setting it up so whatever is on one server is continuously on the other one so that it’s ready to go in the event of a failure.

Disaster recovery would involve backups to recover from in case data is compromised, corrupted, or destroyed. Firewall configurations would be stored that could be recovered from. Documentation would also hopefully contain a solid knowledgebase to look at in the case of a key employee not being available.

Generally, the more money you spend on BC and DR, the less downtime you will have due to BC, and DR plans are able to be performed faster and more effectively (Vandegrift, 2010).
