What is Disaster Recovery?

Disaster Recovery is the process of recovering vital technological infrastructure and system of an organization following a natural or human-induced disaster and thereby resuming its operations to normality as fast and effectively as possible.

A disaster can be anything, from a cyber-attack to equipment failure or natural disruptions that can threaten a company’s business and its theatre of operations. Thus, the goal of DR is to enable an organization to operate normally in case of a disaster and have a quick recovery to mitigate its losses as much as possible.

The process involves planning and execution of the plan by testing it and a physical site for restoring operations.


Importance of DR

In today’s world of high availability dependent business, downtime tolerance is very low. That is why a disaster is the last thing a business needs to experience. Studies show that most of the organizations go out-of-business after they experience a disaster that it could not recover from. This is precisely why Disaster Recovery has become so very important nowadays. DR can help organizations do exactly what the name suggests: “recovery from disastrous events.”

Importance of DR
  • RPO & RTO :

Recovery Point Objective (RPO) and Recovery Time Objective (RTO) are the two most important parameters in a disaster recovery plan and downtime. The objectives guide organizations to chose an effective DR plan and strategize on that.

Recovery Point Objective or RPO is the maximum age of files the organization must recover in case of a disaster from its backup to restore normal operations. Simply put, it determines the minimum frequency of backups required. For example, if a company has an RPO of 4 hours then, it should back up its data every 4 hours.

Recovery Time Objective or RTO, on the other hand, gives the maximum amount of time that can lapse following a disaster that the organization can bear with in order to restore its files and resume operations. In other words, it is the maximum downtime an organization can tolerate. For example, an RTO of 2 hours means that in case of a disaster or system failure the company can stay down for 2 hours and not more than that.


DR planning and strategy

Generally, a DR plan provides a well-thought-out approach for responding to unforeseen events that tend to threaten a company’s IT infrastructure, including hardware, software, network, and connectivity. Thus, the plan should provide a systematic recovery strategy for resuming normal operations as soon as possible. A risk assessment is done to identify the potential threats to the IT Infrastructure; a detailed DR plan outlines the process of recovery of the most important and sensitive elements of the company.

Disaster Recovery Planning & Strategy


Some of the key components a DR plan must incorporate are:

  1. A policy statement, plan overview and main goals of the plan.
  2. Key personnel and DR team contact information.
  3. Description of emergency response actions.
  4. A diagram of the entire system network and recovery site.
  5. Directions for how to reach the recovery site.
  6. A list of software and systems that required for the recovery.
  7. Sample templates for a variety of technology recoveries.
  8. Tips for dealing with the media.
  9. The proposed action plan to deal with financial and legal issues.
  10. Ready-to-use forms to help complete the plan.


Disaster Recovery as a Service (DRaaS)

There are various IT support service providers available in the market that specializes in disaster recovery and as such offers Disaster Recovery as a Service or DRaaS. It is basically, a cloud-based method of recovery.

DRaaS generally uses cloud resources to protect applications and data from the disruption caused by a disaster: natural or fabricated. It offers full replication and backup of all cloud data and applications while serving as a secondary infrastructure. Simply put, it acts as a new platform or system wherefrom the organization can carry out its business operations while the original system (the system of the organization itself) undergoes repair.

  • Advantages & disadvantages

The biggest advantage of DRaaS is its reduced downtime, i.e. time to return the application to production. It is especially useful for small to medium businesses where the execution of an effective DR plan is unlikely due to lack of expertise.

DRaaS

However, its biggest disadvantage lies in the fact that the organization is totally dependent on the service providers for implementing the plan effectively to meet the company’s RPO and RTO conditions. Also, possible performance issues and migration issues are also associated with it.

  • How to pick a DRaaS provider

There are various DRaaS providers available in the market. Some of them are Acronis, Axcient, Bluelock, EVault, Infrascale, Net3 Technology, Peak 10, Quorum, etc. Choosing a provider suiting your needs can be a very tough job sometimes.
