3. WHAT IS A
DISASTER?

4. A disaster can be anything that
puts an organization's operations at
risk, from a cyberattack to
equipment failures to natural
disasters.

5. WHAT IS
DISASTER
RECOVERY?

6. 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)

7. IMPORTANCE OF
DISASTER
RECOVERY

8. ● 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.

9. 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.

10. DISASTER
RECOVERY
PLANNING

11. ● 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"

12. Types Of
Disaster
Recovery Plans

13. There are three basic strategies that
feature in all disaster recovery plans:
(1) preventive measures
(2) detective measures
(3) corrective measures

14. (1) Preventive measures
Preventive 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 measures
Detective 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 measures
Corrective 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.

15. 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.
