What is Desaster?
For an organisation, anything causing disruptions to operations can be termed as a disaster. It includes a system/server crash or a natural calamity that caused an outage for a complete site.
The Desaster for me is that my laptop is not powering on or not able to start the required software or losing the internet connection Car break down can be a disaster for a person heading to the office.
What is Desaster Recovery(DR)?
Is a Method to regain access to the functionality that was affected by a disaster. Having a Backup Laptop, Internet connection, or car can be termed as Desaster recovery.
When we talk about the organisation, there is another term that comes across is Business Continuity. Now let’s understand “What is Business continuity?”
What is Business Continuity?
Business continuity is advance planning and preparation to undertaken to ensure that an organization will have the capability to operate its critical business functions during emergency events and during the disaster.
For example, if accessing the internet is my priority, then I need to be ready with the continuity plan. I can have a secondary connection that can be used when the primary connection gets down. It is Plan B.
From Organisation perspective, disaster-recovery and business-continuity go hand in hand. When we are discussing the different definitions, it is important to discuss RPO and RTO.
What are RPO and RTO?
A Definition for RPO is “Recovery Point Objective”, and RTO is “Recovery Time Objective”.
For example, we decided to invest in a new business. How much money we are ready to invest before we start seeing the profit will be our RPO. How much time we take to reap a profit will be RTO. RPO and RTO are the measurements for a risk-taking ability of a person or an organisation with minimizing the loss.
In IT, RPO is the maximum acceptable data loss, and RTO is the maximum downtime acceptable for an organisation.
