Disaster recovery is the general name for systems that help support critical business functions. The term business continuity is often associated with disaster recovery.

Before disaster recovery, the definition of the disaster was defined in ISO 22300: 12 as follows:

Disaster

A situation in which widespread human, material, economic, or environmental losses have occurred that exceed the ability of the affected organization, community, or society to respond and recover with its resources.

Disaster recovery is a part of business continuity that focuses on maintaining all aspects of the business despite the disaster. Disaster recovery is a key process in the business continuity process because IT systems are critical to business success in today’s world, and considering that most enterprise workloads are integrated into IT systems.

Business continuity and disaster recovery (BC/DR) often work hand in hand. It plays an important role in data protection strategy and comes with its requirements and strategies.

Disaster Recovery focuses on the survival of the IT system after a failure or disruption, while Business Continuity focuses on what works when disaster strikes. Both disaster recovery and business continuity require planning not only for technical difficulties, but also for physical problems. If a data center experiences a devastating event and some time is needed to repair the primary site, this is where a well-planned BC/DR plan is needed.

The importance of Disaster Recovery: RTO and RPO

IT plays a very important role in business today. As businesses become more dependent on high availability, tolerance for downtime is decreasing. A disaster can have a devastating impact on the business. The production line can come to a standstill, the company can be cut off from the outside world, the shipping system can fail, and the company can be in financial trouble. It has been our experience and observation that many businesses fail after suffering a significant data loss. For this reason, DR is very important.

Recovery Point Objective (RPO) and Recovery Time Objective (RTO) are two important values for disaster recovery and downtime. For example, if an organization has a two-hour RPO, the system has a gap of at least two hours between backup and data loss.

RPO refers to how long the backup system must go back for the business to resume normal operations after a disaster. It determines the minimum frequency of backups (replication).

RTO indicates the maximum time the organization can recover from an off-site disaster (ODM). In other words, it is the maximum downtime that the organization can tolerate.

It should be remembered that Disaster Recovery Plans and various application requirements and expectations vary by organization and industry.

At Tecron, we analyze your system with our team of experts and create a risk map. Our priority is to ensure the continuity of your IT infrastructure as soon as possible without losing any data. The right analysis would be the creation of appropriate DR plans and structures through the right risk definitions.
