CloudCentral Managed Enterprise Disaster Recovery is a managed disaster recovery service for protecting critical infrastructure.
This service works by installing a disaster recovery software agent into each physical or virtual server that requires protection.
There are two service levels catering for different recovery time objectives: Hot and Cold service levels.
Hot Disaster Recovery
The first tier service level provides for ‘Hot’ DR, which provides a one-for-one replica server hosted in the data centre for each protected server. Changes from the protected server in the customer environment are replicated asynconrously in near real-time to the DR replica server located in the data center. In the event of a disaster, upon customer request the DR replica server can be made active within 15 minutes of receiving the request.
Cold Disaster Recovery
Cold DR provides a many-to-one replication of protected servers to a central DR repository hosted within a CloudCentral managed data center.
A DR agent is installed into each protected server, which then replicates changes from the protected server to the DR repository asynchronously in near real-time.
In the event of a disaster, upon customer request, a new virtual server will be provisioned at the data center, and the contents of the protected server will be restored to the newly provisioned server from the DR repository within 2 hours.
