[DR] Changes in Disaster Recovery: A Modern Approach

Written by Moh Heng Goh | Oct 16, 2024 7:44:33 AM

What are the Changes in disaster recovery?

Today’s businesses are pushing for more aggressive recovery goals, focusing on minimising downtime and data loss with near-zero Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs). Edge computing and decentralised systems also add new layers of complexity to disaster recovery, requiring strategies to manage and protect distributed workloads. This article will explore these fundamental changes and trends shaping the modern approach.

Changes in Disaster Recovery: A Modern Approach

Disaster recovery (DR) has evolved significantly in recent years, driven by technological advancements, growing business needs, and an increasingly complex risk environment. Organisations are no longer merely concerned with restoring data after a catastrophic event; they now focus on maintaining continuous operations, minimising downtime, and ensuring resilience.

This article explores critical changes in disaster recovery strategies, highlighting trends that are shaping the future of business continuity and IT resilience.


Shift from Data Recovery to Business Continuity

Traditionally, disaster recovery was synonymous with data restoration after an outage or disaster. The primary focus was securing backups and ensuring data could be restored quickly. However, today's organisations require more than just data recovery—they must keep their operations running seamlessly.

Business continuity has become the overarching objective, with disaster recovery as a critical component of a broader strategy that includes people, processes, and technology.

Trend

There is a shift towards ensuring critical operations continue during and after a disaster. This holistic view integrates disaster recovery into overall business continuity management (BCM) to mitigate disruptions across the enterprise.

 

Cloud-Based Disaster Recovery

One of the most significant changes in disaster recovery is the widespread adoption of cloud-based solutions. Traditional on-premise DR strategies were costly and complex, requiring physical backup sites, hardware, and maintenance. Cloud-based disaster recovery (DRaaS - Disaster Recovery as a Service) offers a scalable and flexible alternative.

With cloud-based DR, organisations can store backups offsite and rapidly spin up virtual servers in the event of a disaster. This eliminates the need for physical infrastructure, reducing capital and operational expenses. Moreover, cloud DR ensures faster recovery processes, sometimes benefiting organisations from near-instantaneous failovers.

Trend

Organisations are increasingly moving towards cloud-first strategies for disaster recovery, as they offer faster recovery times, greater scalability, and reduced costs compared to traditional methods.

 

Automation and Orchestration in DR

Automation has transformed disaster recovery from a manual, time-consuming process into a streamlined, efficient one. Automated tools can detect outages, initiate failover processes, and trigger recovery procedures without human intervention.

Disaster recovery orchestration tools are designed to manage the recovery process, including testing, failover, and failback, with minimal human input.

By automating recovery plans, organisations reduce human error and improve the speed and reliability of their DR efforts. Additionally, regular, automated testing of disaster recovery plans ensures they remain effective and up to date.

Trend

Automation and orchestration are becoming essential components of disaster recovery. They allow businesses to recover faster and with fewer errors while easing the burden on IT teams.

 

Increased Focus on Cybersecurity and Ransomware Resilience

As cyber threats become more prevalent and sophisticated, disaster recovery is increasingly intertwined with cybersecurity. Ransomware attacks, in particular, have become a major driver of changes in DR planning.

Organisations are implementing more robust backup strategies, ensuring data can be quickly restored without succumbing to ransom demands.

Many businesses have also adopted immutable backups that attackers cannot alter or delete. This ensures critical data remains secure and can be recovered without compromise, even in a successful cyberattack.

Trend

Disaster recovery plans now integrate advanced cybersecurity measures to counter ransomware attacks. Immutable backups and enhanced monitoring play critical roles.

 

Recovery Time Objective (RTO) and Recovery Point Objective (RPO) Expectations

Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs) have traditionally been critical metrics for disaster recovery. However, businesses today demand more aggressive RTOs and RPOs. RTO refers to how quickly operations can be restored after a disruption, while RPO measures the amount of data loss that can be tolerated.

Modern DR strategies focus on achieving near-zero downtime and data loss, driven by the increasing dependence on always-on systems and the rise of 24/7 global operations. This has emphasised high-availability systems and continuous data protection (CDP) technologies, which can continuously replicate data to ensure minimal disruption.

Trend

Organisations aim for near-zero RTOs and RPOs, relying on high-availability and continuous data protection technologies to meet these expectations.

 

Edge Computing and Decentralized DR Strategies

As edge computing grows, disaster recovery strategies are also becoming decentralised. Edge computing processes data closer to where it is generated, reducing latency and improving real-time analytics. However, this decentralisation introduces new challenges for disaster recovery, as data and workloads are distributed across multiple locations.

Modern DR plans now account for these decentralised environments by ensuring that data is protected and recoverable at the edge. This requires new approaches to data replication, synchronisation, and failover processes tailored to handle distributed workloads.

Trend

Decentralized disaster recovery strategies are evolving in response to the rise of edge computing, requiring organisations to protect and recover data across distributed environments.

 

Regulatory Compliance and Governance

Compliance with regulatory requirements has always been a critical aspect of disaster recovery planning, but the scope of regulations is expanding. Many industries, including finance, healthcare, and energy, face strict rules governing data protection, business continuity, and disaster recovery.

Recent data privacy regulations, such as GDPR and CCPA, have added complexity to DR, as organisations must ensure that their recovery processes meet stringent data handling and protection standards.

In this context, disaster recovery plans must guarantee the continuity of operations and demonstrate adherence to regulatory frameworks, with robust auditing and reporting mechanisms in place.

Trend

Regulatory compliance requirements increasingly influence disaster recovery strategies, particularly regarding data protection and privacy laws.

 

Summing Up …

Disaster recovery has come a long way from simply backing up data and restoring it after a disaster. Today, the emphasis is on business continuity, cybersecurity, and resilience in a rapidly changing digital environment.

Cloud-based solutions, automation, edge computing, and compliance with regulatory standards drive the evolution of DR strategies, enabling organisations to recover faster, protect critical data, and ensure the uninterrupted flow of operations in the face of disaster.

By staying ahead of these trends, businesses can build more resilient recovery plans that adapt to the demands of modern risks.
