Five key questions about disaster recovery as a service | Computer Weekly
Summary
That’s because DRaaS allows customers to recover quickly from a disaster or other outage, but without the cost of conventional, hardware-based data replication and redundant systems. In both scenarios, DRaaS promises to bring an organisation’s systems back online quickly, without the need to source new hardware and facilities, and with minimal disruption to workflows. Backup is an obvious use case in the cloud because it has the ability to scale and allows firms to move to a pay-as-you-go consumption model for data storage. DRaaS that runs in the public cloud will be slower than dedicated systems, but it will still be faster to recover from than basic cloud-based backup or BaaS. One way DRaaS suppliers can save firms money is by pooling the volume of data protected rather than forcing users to pay a fixed sum per device.
