What is Disaster Recovery as a Service?

Disaster Recovery as a Service (DRaaS) is a cloud-based disaster recovery (DR) solution that can be more cost -effective than traditional solutions. In DRaaS, a cloud services provider is responsible for maintaining your organization’s entire DR infrastructure, including backups of your applications and data. In the context of disaster recovery plan versus business continuity plan, DRaaS is often seen as part of the former. This article takes a detailed look at DRaaS and its different models, factors to consider before adopting DRaaS, the advantages and disadvantages of DRaaS, and how it differs from (Backup as a Service (BaaS).

Function of DRaaS

In DRaaS, a third party provides a cloud-based backup system that takes over and prevents business disruption when disaster hits an organization’s IT infrastructure. The typical DRaaS solution comes with a service-level agreement (SLA) that details the customer’s requirements and expectations from the service provider. In the event of a disaster, the provider implements the customer’s DR plan, as stipulated in the SLA.

DRaaS is flexible, as it can accommodate both physical servers in the customer’s own data centers and virtual servers residing in the cloud. But the backup system itself is off -site, as it is based in the cloud. Thus, a DRaaS solution means that you do not have to maintain costly secondary data centers. In addition, as the provider maintains a globally distributed architecture, you can be confident that your DR plan will be implemented no matter what. DRaaS is also ideal for organizations without the required expertise to maintain their own DR efforts.

Before signing up with a DRaaS vendor, comprehensive DR planning is required to prevent spending on an inadequate solution. One thing to look at is the provider’s ability to meet your recovery time objective (RTO), or the maximum amount of time your organization can afford to go down without incurring significant financial costs. This may mean balancing your RTO requirements with the cost, since solutions with more features can be expensive. Solutions can range from completely managed to attended to self-service, with the first one being more expensive than the others.
