Business Continuity vs Disaster Recovery

When thinking of a disaster, you normally imagine earthquakes, floods, tornados, landslides, and so on. A disaster is a sudden accident or a natural catastrophe that brings great damage, loss, and disruption. Disasters may happen anywhere and sometimes cover an entire city or even a region.

Considering the IT industry, a disaster may also happen because of a human error, equipment malfunction, and malware attacks. The most painful result of disasters is data loss, which may adversely affect your business reputation. Therefore, it is important to have a solution for protecting your data when a disaster strikes. So you need a good, simple, and reliable plan to protect your business from data loss, downtime and, eventually, from profit loss or bankruptcy. Far-seeing companies usually consider two approaches: Business Continuity and Disaster Recovery.

Business Continuity vs Disaster Recovery

Business Continuity is aimed at establishing non-interrupted business operations, including but not limited to the IT. That is, business continuity presumes no downtime. Disaster Recovery, on the other hand, is focused just on bringing up the IT services and may presume a downtime.

Now, let’s look closer at these two.

Business Continuity

Business continuity is the capability of your company to continue services at an acceptable level, following a disruptive accident. Business continuity should identify the essential functions of your business, determining systems and processes that must be sustained. Business continuity takes into account any possible business disruption.

The Business Continuity Plan is aimed at the development of procedures that ensure the continuation of your company’s mission-critical functions during and after a disaster. To establish the Business Continuity Plan you need to develop certain procedures that will help you continue operation when disaster strikes. In other words, the Business Continuity Plan ensures delivery of key services and products during and after a disaster as well as ensures your business survival.

A successful Business Continuity Plan should cover the following issues:

  • Defining your business priorities
  • Identification of your most important systems that should be maintained during any outage
  • Identification of resources involved
  • Identification of steps that should be taken to ensure service continuity
  • Recording key staff and vendors contact information to make sure they are easily accessible during a disaster

Disaster Recovery

Disaster recovery is a part of Business Continuity and describes how your company’s IT operation can be resumed after a disaster. The overall idea of disaster recovery is to develop a plan that will enable your IT department to have all business-critical systems up-and-running after a disaster.

Time is a crucial factor. The faster your IT infrastructure is restored, the quicker you can provide IT services to your service users. In particular, the Disaster Recovery Plan is aimed at restoration of data.

Disaster Recovery Techniques

When protecting data, companies rely on:

In a disaster situation, a part of data may be lost, and you have to deal with it. Such data loss happens in the time gap between last successful backup and your VM failure. This is called the Recovery Point Objective (RPO), which defines the amount of data you will lose. Recovery Time Objective (RTO), defines the maximum downtime your business can afford. NAKIVO Backup & Replication effectively reduces your RPO to a minimum, applying the following features:

  • More frequent VM backups to lower the RPO;
  • Scheduling regular backups with an interval, which is no more than your RPO.

Business Continuity vs Disaster Recovery? Or both?

It is important to mention that the Business Continuity Plan is more comprehensive in comparison with the Disaster Recovery Plan. The Business Continuity Plan may include problems with staff (illness or departure of key team members), power failure, hacker attacks and malware infections. It is focused on non-interrupted business operations, describing how your company should be prepared to unexpected risks.

Unlike the Business Continuity Plan, the Disaster Recovery Plan is only a part of the business continuity process. It describes specific steps and technical solutions to recover sensitive data within the shortest time span and should actually define the amount of time during which services will be unavailable.

To ensure adequate protection of your business, the best solution would be the implementation of both Business Continuity and Disaster Recovery plans. Moreover, it is also important to:

  • Review your plans for consistency every year;
  • Analyze to ensure that your plans still meet your business needs;
  • Adjust these plans for your business changes.
