What Is Disaster Recovery as a Service?

In the world of technology, threats to data are ever-present. These threats range from natural disasters to cyber-attacks, posing a significant risk to businesses. But fear not, for there is a solution that can help safeguard your data: Disaster Recovery as a Service (DRaaS).

What is disaster recovery as a service (DRaaS)

Disaster Recovery as a Service (DRaaS) is a cloud computing service model that allows businesses to back up their data and IT infrastructure in a third-party cloud computing environment. It provides organizations with a way to recover their data and systems in the event of a disaster, whether due to natural causes or cyber threats.

The primary goal of DRaaS is to ensure that the recovery of data and systems can be done quickly and efficiently, minimizing downtime and the associated costs. This service can be automated and orchestrated so that it doesn’t require manual processes to implement, making it an attractive solution for businesses of all sizes.

Importance of DRaaS

The importance of DRaaS cannot be overstated. In an age where data is a valuable asset, data loss can have severe consequences for a business. DRaaS provides a safety net, ensuring operations can continue even when disaster strikes. It helps to minimize downtime, prevent data loss, and maintain business continuity.

How does DRaaS work?

DRaaS works through a combination of software, hardware, and networking components configured to replicate an organization’s critical data and applications in a cloud-based environment. Following the DRaaS model, a business’s proprietary data and IT infrastructure are duplicated in real-time, ensuring that a current backup is always available. This duplication occurs continuously or at scheduled intervals based on the organization’s preference and recovery needs.

In the event of a disaster, businesses can failover to the cloud environment where their applications will start running on the cloud-based servers instead. This ensures uninterrupted business processes while the original environment is being restored. Once the disaster is resolved and the original servers are safe to use again, the applications and data can be failed back from the cloud to the primary site.

This entire process can be automated by setting predefined business rules, which means the failover to the cloud environment can instantly be activated when a disaster strikes. This allows for a significantly quicker recovery time compared to traditional disaster recovery methods, and ensures business continuity even in the face of unexpected disruptions.

DRaaS advantages & disadvantages

Like any technology, DRaaS comes with its own set of advantages and disadvantages.


  1. Increased reliability and uptime: DRaaS ensures your business can continue operating even after a disaster.
  2. Cost-effectiveness: With DRaaS, there is no need for expensive on-site disaster recovery infrastructure.
  3. Scalability: As your business grows, your DRaaS solution can easily scale to meet increased demands.


  1. Dependence on a third-party provider: Your business could be affected if your DRaaS provider experiences issues.
  2. Potential security risks: Storing sensitive data off-site could expose it to cyber threats.
  3. Latency issues: Depending on the location of the DRaaS provider’s servers, latency issues may affect performance.

DRaaS vs Backup as a Service

While both DRaaS and Backup as a Service (BaaS) aim to protect data, they do so in different ways. Backup as a Service stores copies of data, which can be restored in case of loss. However, it does not provide a secondary operational site like DRaaS does. DRaaS not only backs up data but also completely replicates your IT environment, ensuring uninterrupted business continuity. Both backup and disaster recovery are connected concepts that businesses should always consider together.

Evaluating DRaaS

Disaster Recovery as a Service is a vital tool for businesses looking to protect their data and ensure business continuity. While there are some potential drawbacks, the benefits of DRaaS significantly outweigh them, making it an excellent investment for businesses of all sizes. By understanding what DRaaS is and how it works, businesses can make informed decisions about their disaster recovery plan.
