disaster recovery as a service - DR-as-a-Service

A combination of the acronyms DR (disaster recovery) and SaaS (software as a service / storage as a service). The term DR-as-a-Service refers to an "always on" hosted disaster recovery solution, where the service provider or vendor, is responsible for deploying and managing applications and services required to support an organization's mission critical activities.

DR-as-a-Service targets small and medium sized businesses (SMB) by eliminating the need for upfront capital expenditure for  in-house IT expertise, and hardware deployments. As with SaaS, DR-as-a-Service is hosted remotely and pricing is based on a monthly fee.
