UCover’s Disaster Recovery as a Service architecture

Alternative to Business Recovery Plan, Disaster Recovery Plan as a service is a growing solution, it attracts because of it’s recovery speed, it’s simple implementation and the decrease of associated costs. 

UCover DRaaS is structured in two spaces

These 2 spaces are used in case of Disaster Recovery, or during DRAaS testing. They are dedicated to the DRaaS technical implementation. They are empty when the client’s system is operational, in nominal mode. In case of Disaster Recovery, they are filled according to needs.

  • The Rescue space : The IT elements on DRAaS scope are recovered in this virtual space, locate in Cloud.
  • The Fallback space: This space is another physical location that allows reconnection to the rescue space, giving access to all recovered IT element

The rescue space

The rescue space is a virtual space in the Cloud. Clients have to plug into it to access their DRaaS. It’s used for disaster recovery or during DRP testing. Image system and data recorded are restored in this virtual space.

The Fallback space

The Fallback space is the physical space where business activity is restored. Once DRP is activated, the fallback space will be interconnected to the rescue space and the client will be able to access the recovered machines.

Infrastructure UCover by Nuabee

The 2 functionnal modes of our DRaaS solution : Nominal & Rescue

Nominal mode

A backup plan is built upstream, in nominal mode. Nominal mode is when the entire infrastructure of the client computer system is connected and functional. It sends data to the cloud for backup.


Back up data by replicating it in the cloud. Application data, systems and servers are saved.

Cloud infrastructure’s costs

Unlike the traditional PRA, Virtual machines are not billed outside recovery tests and the Disaster Recovery launch.

Rescue mode

The rescue mode is the mode activated right after a disaster : the customer then connects to his space, built upstream on the public cloud of Orange Business Service: Flexible Engine.

How does it work ?

When the main site is offline or impacted Our Disaster Recovery as a service solution gives acces to a virtual rescue space dedicated to each client. All element in DRP scope will be restaured in this virtual space (servers, networks ..). During the time your main site is down, this virtual spaces replaces it, allowing business continuity.

Recovery times

Applications and data are restored within minutes or hours, depending on the selected solution.
