What Is a Disaster Recovery Plan

26 September 2024

Businesses can be hit by disasters at any time without prior notice, whether from natural disasters or from cyber-attacks. It can cause immediate and severe consequences that are devastating.

A disaster recovery plan is more than just a set of instructions - it is a crucial document that serves as a blueprint for ensuring the survival as well as recovery of your business in the event of a disaster.

This article takes a look at the important components of such strategies and the way they protect businesses in times of emergency.

What are Disaster Recovery Policies

Disaster recovery policies or a disaster recovery plan are documents that prepare organisations for responding to interruptions caused by cyberattacks, natural disasters or equipment failures.

Such plans form part of business continuity strategies aiming at quick restoration of IT and technological infrastructure.

Main objectives are disruptions of operations, protection of critical data, fast system recovery, and minimization of risks of data loss and system failures.

For a smooth recovery, businesses can use computer monitoring and management for real-time monitoring and response to infrastructure disruptions to prevent downtime during unexpected events.

Key Steps of a Disaster Recovery Plan

• Risk Assessment: Possible risks & vulnerabilities are the first steps towards creating a plan. This assessment prioritises resources and tailors strategies to specific threats.
• Business Impact Analysis: Knowing what an impact a disaster could have on different business functions is critical. Such analysis highlights critical processes, systems and data that require immediate attention during recovery.
• Recovery Strategies: This plan should define recovery strategies for IT systems / data / operations which should include data backup and restoration methods, system failover methods and alternative work arrangements.
• Communication Plan: A crisis requires effective communication. Implementing services like a dedicated IT Service Desk keeps key personnel and stakeholders informed and issues or outages can be resolved quickly to keep operations flowing during recovery efforts.
• Testing and Training: It is important to test and drill the plan regularly. Training employees on their roles and responsibilities helps with recovery.
• Documentation and Updates: The disaster recovery plan should be a living document that should be updated as the organisation's infrastructure, systems and processes change.

What Should a Disaster Recovery Plan Include?

• Clear Objectives: The plan should have recovery time objectives (RTO) and recovery point objectives (RPO).
• Data Backup and Recovery: Critical data and systems need strategies for backing up - off-site storage and cloud solutions.
• Alternative Work Arrangements: Planning for temporary work locations, remote work setups or outsourcing may help operations continue during a disaster.
• Emergency Response Procedures: Procedures to respond to different emergencies like fires, cyberattacks or natural disasters should be defined.
• Recovery Testing and Maintenance: Regular testing and maintenance keep the plan current.

Data Recovery Plans: Industry Applications

Disaster recovery plans don't work for everyone; they're tailored for each industry. Explore how sectors use the plans:

• Manufacturing: Many disaster recovery plans involve protecting and rapidly restoring production line functions and supply chain operations. Key elements include securing data regarding supply chain logistics and production schedules to minimise downtime and speed recovery.
• Finance: The emphasis is on securing sensitive customer data and financial transaction systems to meet regulatory requirements and build customer trust. Most financial institutions have robust data encryption and real time data replication so that all transactional data can be restored quickly.
• Healthcare: From large to small clinics the main priorities are maintaining patient records and ensuring that healthcare delivery systems are in operation. Healthcare disaster recovery plans often include EHR system backups and alternative care sites in case of major incidents.
• Retail: Brands protect customer information while maintaining e-commerce operations. Typical plans could cover quick recovery of online sales platforms and protection of payment processing systems against transaction fraud during downtime.
• Education: Students and academic data have to be protected at institutions. Often their recovery strategies involve restoring access to digital learning platforms and backing up research data to avoid disruption of academic work.

With Business Antivirus Solutions and IT monitoring, healthcare and finance can ensure that sensitive data is protected and systems are quickly restored after an intrusion.

Real-World Application of Disaster Recovery Plans

• Delta Air Lines used its disaster recovery strategies during a 2016 power outage using redundant systems and real-time data replication. Such preparation helped them to limit the effect of the outage, showing how well planned disaster recovery measures can restart operations and preserve service continuity.
• Salesforce & Netflix also showed off their disaster recovery plans during major outages. Salesforce utilised redundant data centres and Netflix used fault tolerant infrastructure across several AWS regions to recover quickly from potentially crippling disruptions. Such examples demonstrate the need for robust and tested disaster recovery protocols.
• Johnson’s & Johnson’s ransomware attack in 2017 highlights what should a disaster recovery plan include: Strong incident response protocols, regular backups, and strong security enable rapid containment and recovery. Their proactive measures helped them restore services and protect sensitive data quickly.
