Creating a Disaster Recovery Plan
Bad news seems constant, so it’s no surprise that crises feel inevitable. While hoping for the best is important, we should also prepare for the worst. Here’s why creating a disaster recovery plan is essential.
A well-crafted disaster recovery plan plays a pivotal role in justifying the impact of natural disasters on business operations, regulatory compliance, and data integrity. Moreover, it serves as a lifeline in expediting recovery from cyber threats, as evidenced by recent breaches at prominent organizations like Infosys and Boeing.
If your organization’s disaster recovery plan is outdated, inadequate, or non-existent, recent events should serve as a wake-up call to reconsider, update, or establish a recovery strategy without delay.
So, what precisely is a disaster recovery plan, and what elements should it encompass?
Here are eight crucial steps to formulate a disaster recovery plan that not only safeguards against data loss but also fosters business continuity and ensures adherence to sensitive data protocols and service level agreements (SLAs).
8 Steps to Create a Disaster Recovery Plan
Establishing a Disaster Response Team and Defining Responsibilities
Establishing a Disaster Response Team is crucial for effectively managing crises and coordinating recovery efforts while ensuring clear communication with employees, customers, and stakeholders.
The team’s responsibilities should be well-documented, assigning specific tasks to each member to ensure smooth operations during emergencies. It’s also essential to have backup personnel designated for key roles in case the primary leads are unavailable.
Establishing Clear Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs)
Two critical elements of any robust disaster recovery plan are setting clear Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).
RTO refers to the maximum acceptable downtime for an application before it starts impacting your business operations. This duration varies based on the application’s criticality:
- RTO near zero: For mission-critical applications that require immediate failover capabilities.
- RTO of four hours: Applicable to less critical systems where there’s time for on-site recovery from bare-metal backups.
- RTO of eight or more hours: Suitable for nonessential applications that can remain offline for extended periods without significant repercussions.
On the other hand, RPO defines the maximum data loss tolerable before it adversely affects your business. This aspect influences how frequently data backups need to be performed:
- RPO near zero: Utilize continuous replication for mission-critical data, ensuring minimal to no data loss and seamless business continuity.
- RPO of four hours: Opt for scheduled snapshot replication to minimize data loss.
- RPO of 8-24 hours: Use existing backup solutions for data that can be reconstructed from alternate sources.
The decision regarding RTOs and RPOs also considers cost implications, as more frequent and real-time replication or backup solutions typically incur higher expenses. By aligning RTOs and RPOs with your business needs and available resources, you can create an effective disaster recovery strategy that minimizes downtime and data loss while balancing cost-effectiveness.
Designing a Network Infrastructure Blueprint
A comprehensive blueprint of your network infrastructure is crucial for efficient system recovery, particularly in the event of a cyberattack or network corruption. It’s essential to categorize different system components based on their importance to business continuity, indicating their priority as mission-critical, essential, or nonessential. This prioritization ensures that services are restored in the appropriate order during recovery efforts. Additionally, including system dependencies in the blueprint is vital, as they can influence the prioritization and sequence of recovery tasks.
Key elements to include in your network infrastructure blueprint:
- Network Topology:
- Diagram illustrating the layout of your network, including routers, switches, firewalls, and access points.
- Indicate network segments, VLANs, and interconnections between devices.
- Servers and Services:
- List of servers hosting mission-critical, essential, and nonessential services.
- Identify critical applications, databases, email servers, domain controllers, and file servers.
- Data Storage:
- Outline storage solutions such as SAN (Storage Area Network) or NAS (Network Attached Storage).
- Specify storage volumes, RAID configurations, and backup repositories.
- Connectivity:
- Document internet connections, WAN (Wide Area Network) links, and VPN (Virtual Private Network) connections.
- Include details of ISP (Internet Service Provider), bandwidth capacities, and failover mechanisms.
- Security Measures:
- Describe firewall rules, intrusion detection/prevention systems, and antivirus solutions.
- Note security policies, access controls, and encryption protocols in use.
- System Dependencies:
- Identify dependencies between servers, services, and applications.
- Highlight dependencies on external systems or third-party services.
- Disaster Recovery Plan:
- Summarize the disaster recovery plan, including backup schedules, recovery procedures, and testing protocols.
- Specify roles and responsibilities of personnel involved in disaster recovery efforts.
- Documentation and Contacts:
- Provide links or references to detailed documentation for individual components.
- Include contact information for key personnel, vendors, and support providers.
Maintaining an up-to-date and well-organized network infrastructure blueprint is essential for effective disaster recovery planning and ensuring business continuity in the face of unforeseen events or cyber incidents.
Choosing an Effective Disaster Recovery Solution
When selecting a disaster recovery solution, consider factors such as storage capacity, recovery timeline, and configuration complexity, as they directly impact costs. Often, the choice is between quick recovery times with potential data loss versus maintaining system availability with high complexity and costs.
Opt for a solution like Concertium that offers affordable protection against data loss for your systems and applications.

This minimizes complexity and enables easy restoration of service-level agreements, enhancing overall efficiency and cost-effectiveness.
Creating a Checklist for Activating the Disaster Response Plan
An effective business continuity plan hinges on identifying the specific criteria that warrant the activation of your disaster response plan. This ensures that your recovery team can initiate the appropriate response without expending resources unnecessarily or reacting disproportionately to minor incidents. Key considerations include:
- Type of Disaster:
- Determine what types of events qualify as disasters, such as cyberattacks, major system failures, or prolonged power outages.
- Severity of Impact:
- Assess the severity of the incident’s impact on critical business operations, infrastructure, data centers, or services.
- Evaluate the potential financial, operational, or reputational risks associated with the event.
- Extent of Data Loss or Damage:
- Consider the extent of data loss or damage to essential systems, applications, and databases.
- Evaluate if the incident compromises data protection measures or backup and recovery capabilities.
- Availability of Resources:
- Determine if there are adequate resources, including personnel, equipment, and infrastructure, to manage the recovery process effectively.
- Assess the availability of alternative workspaces or backup facilities if primary locations are compromised.
- Impact on Customers and Stakeholders:
- Consider the impact on customers, stakeholders, and partners, including disruptions to services, communications, or contractual obligations.
- Evaluate potential legal or regulatory implications and the need for transparent communication.
