Mastering Disaster Recovery – Best Practices in 2024

From natural calamities to cyber threats and system failures, organizations face numerous challenges that can cripple their operations if not addressed proactively. 

This is where disaster recovery steps in, offering a lifeline to ensure uninterrupted business continuity and minimize the impact of unforeseen events.

At its core, disaster recovery is the set of policies, tools, and procedures that enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. 

In this guide we will explore the importance of disaster recovery planning, delve into best practices for mitigating risks, and provide insights to help organizations fortify their resilience against potential disasters.

Understanding Different Types of Disaster Recovery Solutions

To address the potential risks and challenges, it is crucial for businesses to understand the different types of disaster recovery solutions available. These include cloud-based solutions, network-based solutions, virtualized environments, and Disaster Recovery as a Service (DRaaS).

Each solution plays a unique role in the overall disaster recovery strategy. Cloud-based solutions offer scalability and flexibility, while network-based solutions focus on ensuring data redundancy and rapid recovery. Virtualized environments provide the ability to replicate and restore entire systems, and DRaaS offers a comprehensive, outsourced solution for disaster recovery. A well-rounded DR plan may incorporate a combination of these solutions to address various recovery needs effectively. 

For example, cloud-based DR can handle data backups, network DR ensures communication continuity, virtualized DR enables rapid recovery of applications, while DRaaS can provide an overarching solution that integrates each of these elements. 

By combining these solutions, businesses can achieve a more resilient and robust disaster recovery strategy.

The Importance of Regular Testing and Improvement

The work unfortunately does not stop once you have partnered with your ideal disaster recovery solution. A disaster recovery plan is only as good as its last test.

Regular testing ensures that the plan works as intended and that all team members are familiar with their roles during a disaster and that all components, including hardware, software, and personnel, are prepared to respond effectively. 

Testing also verifies that data backups are completed and can be restored quickly, and that all systems are configured correctly.

Below are some tips on how to prepare and test your disaster recovery plan, so that you are prepared to continue business operations.

Testing Best Practices

Preparation

Create a test plan that outlines strategy/simulate real world scenarios

Create an outline delegating responsibilities in the case your cloud environment, network, or on-prem data centers go dark. Create a variety of real world disaster scenarios with step by step instructions so that roles and responsibilities are in each scenario.

Don’t leave it all on one person

Make sure that one person isn’t left responsible for any one step in your recovery plan. Having at least two people per procedure ensures that someone will be available in a crisis situation.

Prepare to document any changes that may need to be made after your test

Make sure your team is taking notes in case of unexpected results or if any unanticipated obstacles are discovered. Record them and report back if changes need to be made. 

Testing your DR plan

Tabletop testing : now that you have prepared a test outline, roleplay a potential disaster and talk through in detail who does what/what steps each person takes during a disaster

Review and update: review and update current DR plan if needed, then perform a tabletop test to ensure that each new step will work.

Data Redundancy and Backup Monitoring

One of the fundamental aspects of disaster recovery is ensuring data redundancy and backup monitoring in the case of a single backup solution failing. By implementing robust data backup strategies in geographically dispersed locations, businesses can mitigate the risk of data loss and expedite the recovery process in the event of a disaster. Below are some common tips for redundant backup strategies.  

Strategies for data backup in multiple locations.

Geographic Diversity: Store backups in multiple geographic locations to protect against regional disasters. This approach minimizes the risk of all backups being compromised in a single event.

Regular Backup Schedules: Implement frequent backup schedules to ensure that data is as up-to-date as possible. The more frequent the backups, the less data loss in the event of a disaster.

Different Storage Media: Use a mix of storage media, such as cloud storage, physical drives, and tapes, to reduce the risk of data loss. This hybrid approach leverages the strengths of various storage options.

Organizations should employ a combination of on-premises, cloud-based, and off-site backups to ensure that critical data is protected and readily accessible. By leveraging geo-redundant storage solutions, businesses can enhance data durability and availability, thereby improving their disaster recovery capabilities.

The role of proactive backup monitoring.

Proactive backup monitoring ensures that backups are completed successfully and that any issues are promptly addressed. This can make an enormous difference to a very common obstacle, as the International Data Corporation reported in 2021 that ⅓ of  respondents suffered problems with backup and restore reliability.

Automated monitoring tools can alert IT teams to failed backups, allowing them to take corrective action before a disaster occurs. Proactive monitoring helps maintain the integrity and availability of backup data, which is crucial for effective disaster recovery.

Creating an Effective Disaster Recovery Plan

Strategies for data backup, system restoration, and communication should be practical and executable, while clearly defined roles and responsibilities of all team members ensures coordinated efforts during a crisis.

So when you are creating a effective disaster recovery plan, consider the below listed tips:

1. Create an Inventory List/Backup Your Data

Compile a comprehensive inventory of all IT assets, including hardware, software, and data, and implement a robust data backup strategy with regular testing to ensure data integrity and rapid recovery.

2. Risk Assessment

Identify potential risks and their impact on the business. This involves understanding both internal and external threats to IT infrastructure.

3. Define RTO and RPO

Establish Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) for each system. These metrics are crucial for setting realistic recovery goals.

4. Develop Diversified Recovery Strategies

Create strategies for data backup, system restoration, and communication. These strategies should be practical and executable under pressure, and diversifying them increases your adaptability and resilience.

5. Assign Roles

Clearly define the roles and responsibilities of all team members involved in disaster recovery. This clarity ensures coordinated efforts during a crisis

6. Document the Plan

Ensure that the disaster recovery plan is well-documented and accessible to all stakeholders. Documentation should be clear, concise, and comprehensive.

7. Test Your Disater Plan

Regularly test the plan and review it for improvements. Continuous improvement is key to maintaining an effective DR plan.

8. Business Impact Analysis (BIA)

Determine the criticality of different systems and data, and their recovery priorities. A BIA helps in prioritizing resources and efforts during recovery, while also highlighting potential losses in sales and expenses affiliated with recovery.

Employee Training and Awareness

Employee training is a critical component of disaster recovery planning. Regular drills and refresher courses ensure that all employees understand their roles and responsibilities during a disaster. It keeps the team prepared and confident in executing the disaster recovery plan. Continuous training helps to reinforce the importance of disaster recovery and keeps employees informed about any updates to the plan.

All employees should be aware of the disaster recovery plan and their specific role in it. This includes understanding how to access the plan, who to contact during an emergency, and how to follow the recovery procedures. Clear communication and regular training help in building a culture of preparedness within the organization.

Recovery Time Objective (RTO) and Its Significance

RTO represents the maximum acceptable amount of time that a system can be offline after a disaster. Different systems may have different RTOs based on their criticality to business operations. For instance, mission-critical applications may have a shorter RTO compared to less essential systems.

A well-defined RTO helps prioritize recovery efforts and allocate resources effectively. It ensures that the most critical systems are restored first, minimizing the impact on business operations. Understanding and setting appropriate RTOs is crucial for effective business continuity planning.

Disaster Recovery in Application Environments

If your business relies mainly on SaaS applications to store and manage data, among other daily operations, properly preparing for disaster recovery will be similar with a few extra steps.

First of all, you will want to understand your application architecture and their connections between different components, then create a disaster plan for all possible scenarios. Find all your fail points and what the impact may be, and make sure DR properly incorporates each of those possibilities so that you are never caught off guard.

Plan for scenarios such as data loss, where critical data is corrupted or deleted, and dependent service loss, where services that applications rely on are unavailable. Develop strategies to recover data and restore service dependencies quickly. For example, have contingency plans for alternative data sources and temporary workarounds to maintain application functionality.

Partnering with an effective DRaaS group will also help maintain data stored across your application environment, and will provide you with the necessary tools to back up and recover your data in the event of a disaster.

Considerations for Cloud-Based Disaster Recovery

Cloud-based solutions can be integrated into your overall DR strategy to provide flexible, scalable, and holistic recovery options. 

They can complement on-premises solutions and offer an additional layer of redundancy by automatically backing up and storing your data across a third-party vendor’s cloud severs with multiple geo locations.

By incorporating cloud-based DR, businesses can also benefit from faster recovery times and reduced complexity in managing DR infrastructure

Evaluating the Pros and Cons of DRaaS
