Disaster Recovery as a Service (DRaaS) provides data replication, hosting, and recovery services from the cloud in the event of a disaster, power outage, ransomware attack, or other business interruption.
DRaaS backs up data, applications, and IT infrastructure to the cloud, with providers typically having geographically dispersed data center footprints. In the event of a disaster, the business will failover to the DRaaS provider’s data center in a different region.
As opposed to traditional disaster recovery methods, which require businesses to operate an off-site DR facility, DRaaS shifts that burden to service providers, and, thus, expands the market beyond the large enterprises that could afford such capital-intensive setups.
