Disasters are inevitable and can disrupt business operations, resulting in direct revenue loss. Whether business operations are compromised because of an unplanned telecom outage, extreme weather, data breach or cyber-attack, businesses — whether small or large — operators need to have solid disaster recovery plans in place. While disaster recovery plans are essential to ensure business continuity, they may do little good if they aren’t tested regularly.
The first step in developing a disaster recovery plan is to understand your environment and identify the potential risks to critical business operations. Through detailed risk analysis, the disaster recovery team needs to list and prioritize the business’ essential functions. Possible risks can be broken into several categories: external risks (natural disaster, human-caused, etc.), facilities-related (power outages, fires, etc.) and risks to data systems and application continuity across multiple, interdependent tiers, including enterprise applications, databases, networks, storage, backup, replication and data protection infrastructures. For each of these risks, disaster recovery (DR) administrators need to determine the likelihood of service disruption; the impact it will have on the organization as a whole, as well as per business line; and what is an acceptable recovery time and recovery point (RTO and RPO).
