RaaS differs from cloud-based backup services by protecting data and providing standby computing capacity on demand to facilitate more rapid application recovery.
[2] RaaS architectural models vary depending on the location of the primary or source production application or data.
It is used to test the RaaS recovery process without disrupting the running application.
Because the sandbox is cloud, the resources are created on demand, paid for while used, and discarded when the recovery testing is completed.
Companies which rely on large cloud service providers such as Microsoft are often unaware that they are responsible for backing up and recovering their data.
