WHAT IS A DISASTER?

A disaster can be anything that puts an organization's operations at

risk, from a cyberattack to equipment failures to natural

disasters.

WHAT IS DISASTER

RECOVERY?

Disaster recovery (DR) is an area of security planning that aims to protect an organization

from the effects of significant negative events. DR allows an organization to

maintain or quickly resume mission-critical functions (most crucial functions) after a

disaster.

Sometimes erroneously called a Continuity of Operations Plan (COOP)

IMPORTANCE OF DISASTER

RECOVERY

●As businesses have become more reliant on high availability, the tolerance for downtime has decreased.

●A disaster can have a devastating effect on a business. Studies have shown that many businesses fail after experiencing a significant data loss, but DR (Disaster Recovery) can help.

RPO and RTO

Recovery point objective (RPO) and recovery time objective (RTO) are two important measurements in disaster recovery and downtime.

● A recovery point objective, or “RPO” it is the maximum targeted period in which data might be lost from an IT service due to a major incident.For example, if an organization has an RPO of four hours, the system must back up at least every four hours.

● RTO is the maximum amount of time, after a disaster, for an organization to recover files from backup storage and resume normal operations. In other words, the recovery time objective is the maximum amount of downtime an organization can handle. If an organization has an RTO of two hours, it cannot be down for longer than that.

DISASTER RECOVERY PLANNING

● A disaster recovery plan (DRP) is a documented process or set of procedures to recover and protect a business IT infrastructure in the event of a disaster.

● Such a plan, ordinarily documented in written form, specifies procedures an organization is to follow in the event of a disaster.

● It is "a comprehensive statement of consistent actions to be taken before, during and after a disaster"

Types Of Disaster

Recovery Plans

There are three basic strategies that feature in all disaster recovery plans:

(1) preventive measures(2) detective measures(3) corrective measures

(1) Preventive measuresPreventive measures will try to prevent a disaster from occurring. These measures seek to identify and reduce risks. They are designed to mitigate or prevent an event from happening. These measures may include keeping data backed up and off site, using surge protectors, installing generators and conducting routine inspections.

(2) Detective measuresDetective measures are taken to discover the presence of any unwanted events within the IT infrastructure. Their aim is to uncover new potential threats. They may detect or uncover unwanted events. These measures include installing fire alarms, using up-to-date antivirus software, holding employee training sessions, and installing server and network monitoring software.

(3) Corrective measuresCorrective measures are aimed to restore a system after a disaster or otherwise unwanted event takes place. These measures focus on fixing or restoring the systems after a disaster. Corrective measures may include keeping critical documents in the Disaster Recovery Plan or securing proper insurance policies, after a "lessons learned" brainstorming session.

There is no one right type of disaster recovery plan, nor is there a one-size-fits-all disaster recovery plan.A disaster recovery plan must answer at least three basic questions:

(1) what is its objective and purpose?

(2) who will be the people or teams who will be responsible in case any disruptions happen?

(3) what will these people do (the procedures to be followed) when the disaster strikes.
