Disaster Recovery 

Business Continuity

What is the difference between disaster recovery and business continuity?

Disaster recovery is the process of getting all important IT infrastructure and operations up and running following an outage. Business continuity differs in that it is the process of getting the entire business back to full functionality after a crisis.

RPO: Recovery Point Objective

Recovery Point Objective (RPO) describes the interval of time that might pass during a disruption before the quantity of data lost during that period exceeds the Business Continuity Plan’s maximum allowable threshold or “tolerance.”

Example: If the last available good copy of data upon an outage is from 18 hours ago, and the RPO for this business is 20 hours then we are still within the parameters of the Business Continuity Plan’s RPO. In other words it the answers the question – “Up to what point in time could the Business Process’s recovery proceed tolerably given the volume of data lost during that interval?”

RTO: Recovery Time Objective

The Recovery Time Objective (RTO) is the duration of time and a service level within which a business process must be restored after a disaster in order to avoid unacceptable consequences associated with a break in continuity. In other words, the RTO is the answer to the question: “How much time did it take to recover after notification of business process disruption?“

RPO designates the variable amount of data that will be lost or will have to be re-entered during network downtime. RTO designates the amount of “real time” that can pass before the disruption begins to seriously and unacceptably impede the flow of normal business operations.

There is always a gap between the actuals – Recovery Time Actual (RTA) and Recovery Point Actual (RPA) – and objectives introduced by various manual and automated steps to bring the business application up. These actuals can only be exposed by disaster and business disruption rehearsals.

Recovery Point Objective (RPO) and Recovery Time Objective (RTO) are two of the most important parameters of a disaster recovery or data protection plan. These are objectives which can guide enterprises to choose an optimal data backup plan.

The RPO/RTO, along with a business impact analysis, provides the basis for identifying and analyzing viable strategies for inclusion in the business continuity plan. Viable strategy options include any which would enable resumption of a business process in a time frame at or near the RPO/RTO.
