In the complex landscape of modern IT, the differentiation between cyber recovery and disaster recovery is crucial for businesses striving to protect their essential data while ensuring continuity. Understanding these distinct strategies and incorporating critical elements such as immutable backups and data categorisation can help organisations establish a robust, prioritised recovery process.

Cyber Recovery vs. Disaster Recovery

Firstly, it's important to clarify the core differences between cyber recovery and disaster recovery. While both strategies are designed to restore data and systems, their focus areas and applications diverge significantly.

Disaster Recovery (DR) aims to restore IT operations after incidents such as natural disasters, power failures, or hardware malfunctions. The primary objective is the quick resumption of business services, minimising downtime and its associated costs.

Cyber Recovery (CR), on the other hand, is specifically tailored to protect and restore systems and data from cyber threats like ransomware or other malicious attacks. The goal of CR is not just to recover data but to do so in a manner that ensures it is free from corruption and secure from persistent threats.

The Role of Immutable Backups

A pivotal aspect of both recovery strategies is the use of immutable backups. These backups are essentially write-once-read-many (WORM) models; once data is written, it cannot be changed or deleted for a set period. This immutability protects data integrity by preventing alteration or deletion during the retention period.

Immutable backups are particularly beneficial in cyber recovery scenarios where the threat of malware embedding itself into the backups can be a significant risk. In such cases, even if attackers encrypt or corrupt your active data, the immutable snapshots provide a fail-safe that ensures the availability of an unaltered version for recovery.

Data Categorisation: Facilitating Prioritised Recovery

Efficient recovery processes require more than just well-managed and secure backups; they demand a strategy tailored to the priority of data assets. This is where data categorisation steps in, providing a framework to identify what data must be recovered first to minimise business impact.

Allocating resources to restore high-priority data quickly, such as financial records or customer information, ensures that critical functions can resume operation and that compliance requirements are met without delay. Organisations can use data categorisation to define recovery time objectives (RTO) and recovery point objectives (RPO) based on the sensitivity and importance of different data types.

Implementing Immutable Backups and Data Categorisation

Implementing these strategies effectively requires careful planning and execution. In order to avoid performance issues, it's also recommended that categorisation occurs in your data snapshots, rather than in your live applications.

1. Define your data categories: Understand your data hierarchy. What data is business-critical? What demands quicker recovery? By categorising data based on its importance to business functions, you can tailor your recovery strategy to meet precise needs.

2. Implement immutable backup solutions: Choose a reliable backup solution that supports immutability. Solutions like object storage or specialised backup software can offer robust data protection ensuring your backups are safeguarded against tampering and deletion.

3. Test recovery processes: Regularly testing your backup systems and recovery plans is essential to ensure they will function as expected during an actual crisis. This testing should include scenarios involving both disaster recovery and cyber recovery.

4. Educate your team: Ensure that all relevant personnel understand the categorisation and recovery processes. This understanding helps in minimising errors and ensuring smooth execution when these processes are invoked.

5. Maintain compliance and update policies: Regulatory considerations often play a crucial role in data management practices. Regular reviews and updates of your policies to comply with laws and industrial standards are crucial.

Conclusion

By differentiating between cyber recovery and disaster recovery, and leveraging tools like immutable backups and effective data categorisation, organisations can enhance their ability to recover from incidents promptly and efficiently. These measures not only safeguard sensitive data but also facilitate operational continuity, ensuring organisations can withstand and recover from both natural and man-made incidents promptly. This comprehensive approach is fundamental in today's digital age, where data integrity and availability are key to sustaining business momentum.
