Complete Guide to Disaster Recovery Plan Examples to Ensure Business Continuity

To prevent this, a Disaster Recovery Plan (DRP) is developed as part of a business risk management and disaster preparedness strategy. This article provides a comprehensive guide to the concept of DRP, the key components in its development, implementation steps, and real-world examples of DRP application in the business world.

What is a Disaster Recovery Plan?

Before discussing implementation, it is important to understand the basic definition.
A Disaster Recovery Plan (DRP) is a strategic document that contains procedures for recovering systems, IT infrastructure, data, and business processes after a disruption or disaster. The purpose of a DRP is to ensure that operations can resume with minimal downtime and controllable data loss.

A DRP typically involves determining:

• Critical systems and processes
• Data backup and recovery strategies
• Primary and secondary data center locations
• Emergency communication and coordination mechanisms

Important terms to know:

DRP is widely used in the financial, telecommunications, e-commerce, logistics, healthcare, and public services sectors.

Strategic Benefits of a Disaster Recovery Plan for Companies

To understand the importance of DRP, we need to look at the operational and managerial benefits it provides. With a well-developed disaster recovery plan, organizations can gain the following advantages:

Strategic Benefits of a Disaster Recovery Plan for Companies

Before developing a technical disaster recovery plan, organizations need to understand the strategic benefits they will gain. Each of the following benefits is directly related to business continuity, reputation, and long-term operational efficiency.

1. Ensuring Operational Continuity

A DRP helps ensure that critical systems and services remain operational or can be restored quickly after an outage. This is crucial because many business processes today rely on digital technology, including customer transactions, internal systems, and application services. Without a recovery plan, downtime can cause operational disruptions that have a domino effect on all business units.

• Backup systems (failover) and data replication can maintain service continuity.
• Operations continue even if the primary data center experiences an outage.
• Reduce service interruptions that directly impact customers.

2. Protecting Data and Information Assets

Layered backups, replication, and other data protection mechanisms in DRP help companies avoid permanent data loss. Data is a strategic asset for companies, ranging from customer information and financial transactions to internal documentation. Data loss can have serious consequences, both operationally and legally.

• DRP ensures data remains available even in the event of a cyberattack or system failure.
• Data copies are stored in different locations (off-site or cloud storage).
• Backup verification and testing are conducted to ensure data can be fully recovered.

3. Minimizing Financial Losses

Extended downtime not only disrupts operations but also causes direct and indirect losses, such as lost revenue, SLA penalties, and system repair costs. With a DRP in place, recovery time can be minimized, thereby reducing the financial impact.

• Planned recovery prevents companies from entering "crisis mode".
• The use of backup resources speeds up recovery without improvisation costs.
• It reduces the potential loss of business opportunities during the disruption.

4. Maintaining Customer and Business Partner Trust

Service reliability directly affects a company's reputation. By demonstrating preparedness and quick response when incidents occur, customer and partner trust can be maintained.

• Transparency in incident handling provides a sense of security for stakeholders.
• The company is considered to have good governance and operational control.
• The customer experience is not significantly disrupted because recovery is rapid.

5. Supporting Regulatory Compliance

Many industries have formal requirements related to data security and operational continuity, such as ISO 27001, PCI-DSS, and POJK provisions for financial service institutions. DRP is part of meeting these requirements.

• DRP documentation can serve as evidence of security controls during the audit process.
• Regulatory compliance helps prevent sanctions, penalties, or audit failures.
• Supports measurable, monitorable, and accountable IT governance.

Key Components in Developing a Disaster Recovery Plan

To produce an effective DRP, the plan must include the following core components. Each component complements the others and forms a comprehensive preparedness system.

1. Risk Analysis and Threat Identification

Organizations need to map relevant potential disasters based on location, business model, and IT infrastructure. For example:

• Earthquakes, floods, fires
• Ransomware and malware attacks.
• Hardware or network failure
• Human error

2. Identify Critical Business Systems and Processes

Not all systems have the same priority. Recovery should focus on systems with the greatest business impact.

3. Data and IT Infrastructure Recovery Strategy

Strategies may include:

• Scheduled backups (full/incremental/differential)
• Fast replication.
• Failover to the cloud or secondary data center
• Setting RTO and RPO

4. Emergency Communication Procedures

Includes internal information flow, roles of each DR team member, customer notifications, and coordination with service providers.

5. Regular Testing and Evaluation

Simulations help ensure that the DRP can be executed without obstacles. The plan needs to be updated in line with changes to the system and business processes.

Practical Steps for Developing a Disaster Recovery Plan

To effectively implement a DRP, organizations can follow these steps:

1. Form a cross-departmental DR team.
2. Conduct a risk assessment and develop realistic disaster scenarios.
3. Clearly document step-by-step procedures.
4. Integrate technologies such as cloud-based backup and automatic failover.
5. Train and conduct regular simulations to test readiness.

Examples of Disaster Recovery Plans in Companies

To understand the practical implementation of a DRP, here are three publicly documented cases that are widely used as references.

1. Maersk (2017) – Global Ransomware Attack

Context:
Maersk experienced a NotPetya ransomware attack that halted global operational system activities.

DRP Implemented:

• Recovery was carried out using offline backups that were not infected.
• IT infrastructure reconstruction was carried out in a structured manner: domain controllers, logistics systems, port systems.
• Priority was given to high-value business services.

2. Bank Indonesia (2021) – Ransomware Attack Attempt

Context:
There was an attack attempt on the internal network.

DRP Implemented:

• Network segmentation limited the affected area.
• Data recovery was performed from validated backups with checksum integrity.
• Rapid activation of the Incident Response Team (IRT) isolates and restores services.

3. Telecommunications Company in Indonesia – Data Center Flooded

Context:
The main data center is unusable due to severe flooding.

DRP Implemented:

• Failover activation to the secondary data center (warm site).
• Utilization of the cloud as a temporary capacity buffer.
• Transparent communication with customers and business partners.

Data center locations must consider geographical risks, and cloud support can accelerate recovery.
