Disaster Recovery as a Service

What Does Disaster Recovery as a Service Mean?

Disaster recovery as a service (DRaaS) is a cloud computing and backup service model that uses cloud resources to protect applications and data from disruption caused by disaster. It gives an organization a total system backup that allows for business continuity in the event of system failure.

DRaaS is often offered in conjunction with a disaster recovery plan (DRP) or business continuity plan (BCP).

DRaaS is also known as business continuity as a service (BCaaS).

Techopedia Explains Disaster Recovery as a Service

DRaaS enables the full replication and backup of all cloud data and applications while serving as a secondary infrastructure. It actually becomes the new environment and allows an organization and users to continue with daily business processes while the primary system undergoes repair. DRaaS allows these applications to run on virtual machines (VM) at any time, even without a real disaster.

DRaaS is also available to organizations that employ on-premise solutions, making it a workable gateway and sandbox to test cloud computing. It requires an organization to replicate a system on the cloud without discarding its on-premise system and, once backed up, enables testing of such a system.

DRaaS advantages are as follows:

  • Multisite: Because DRaaS is 100 percent cloud computing, resources are replicated to many different sites to ensure continuous backup in the event that one or more sites is unavailable.
  • Array agnostic: DRaaS replicates any environment and does not favor one vendor or platform.
  • Granular or comprehensive: Depending on customer requirements, if not all data requires backup, an organization can reduce costs with flexibility protection.
