In the previous article where the development of an IT disaster recovery plan is discussed in detail, we also briefly touched the option of Disaster Recovery as a Service (DRaaS). Here, we will examine this third-party IT disaster recovery plan in depth.

What is DRaaS?

DRaaS is the provision of a replica of servers, processors, databases and networks that organizations use in the event of any unforeseen natural or a man-made disaster, leading to the cessation of all IT operations. This disaster recovery option is provided by third-party vendors on contractual or metered basis.

Different Categories of DRaaS

Even though on a structural level, all of DRaaS options are similar to each other, but they can categorize into three different types according to their modes of implementation.

Self-service DRaaS

As the name suggests, this DRaaS model provides organizations all the necessary tools to carry out their disaster recovery backup replications on their own. In self-service DRaaS, the company itself is responsible for monitoring and managing the recovery environment. The company’s internal IT department of the company will manage all the facets of the disaster recovery. From planning to testing and bringing everything back online, the onus of the success of DRaaS solely lies on the IT personnel of the company.


  • It is the cheapest DRaaS model
  • It comes with less reliance on the third-party
  • Your own people will be better able to prioritize the implementation of DRaaS


  • You will have to designate time and human resource since your own staff will be responsible to execute the plan
  • Without sufficient IT bandwidth and handful of IT personnel, it will be extremely difficult to effectively implement a self-service DRaaS

Assisted DRaaS

Assisted DRaaS model is a mix and match where a third party vendor will provide necessary DR tools to companies and act as an advisor through the phases of testing, implementation, and management of the plan. A strong communication channel is needed here so that the IT personnel of the company will remain in contact with the advisory team of DRaaS providers. In some cases where internal IT team is not available or unable to execute the disaster recovery, the third-party can directly act to maintain the order of recovery environment.


  • Like self-service DRaaS models, companies don’t have to overspend in getting this disaster recovery plan
  • This DRaaS model is fitting for the organizations with sufficient IT infrastructure and resources but they are in need of expert advice and guidance in the implementation and management of the recovery plan


  • Poor communications can neutralize the benefits of this recovery model
  • In most of the cases, these DRaaS models come without a service-level agreement which means at the end of the day the organization itself will be liable for executing disaster recovery

Managed DRaaS

This model entails the complete outsourcing of your disaster recovery plan. Here the service providers will be responsible to devise, execute and manage the recovery model. A team of IT professionals from vendors is at the helm to steer the recovery environment in managed DRaaS. They can also work with IT personnel of the company to streamline the recovery operations.


  • This DRaaS model is the most comprehensive and provides support and assurance of IT disaster recovery for all types of businesses
  • It is best suited for organizations where IT teams are already overworking in running the strategic operations
  • Managed DRaaS models often come with service-level agreement, meaning the vendor will be solely responsible for the replication and recovery of IT operations of the company


  • Managed DRaaS models can be pretty expensive
  • You will be entirely dependent on the expertise of your DRaaS vendor

A fair comparison between these three DRaaS model infers that Managed DRaaS is the best if you really want to establish a sound backup in the event of any IT-related disaster.

Factors to Consider in Hiring DRaaS providers

If you are convinced that DRaaS is the right choice to manage any IT disaster, then there are few questions which should be discussed and answered first.

  • What percentage of your operations will DRaaS providers be able to run in case of any disaster?
  • What are the conditions that would prompt the action of DRaaS providers?
  • How things will proceed if they are unable to deliver DR services?
  • How the unserved customers will be dealt?
  • Will this temporary failover change the user experience and access to your services?
  • Will the services rendered be charged in a bundle or separately?
  • Are recovery expenses included the upfront cost?

You can proceed with the DRaaS vendor who can satisfy most of the above-mentioned questions.
