Putting together Disaster Recovery Policy and would like to include definitions for the DR Standby Servers classifications as depending on the business application criticality, we will be directing the level of DR capability required.
Here is what I have put together but would like feedback on whether they are appropriate.
Cold-Standby Server ? A server that is pre-assigned for provision of DR capability for the associated application, although it is utilized for other purposes during normal operations (e.g. development/testing environment for associated environment). This server will need to be re-configured for use if required for disaster recovery purposes.
Warm-Standby Server ? A server that is dedicated to providing DR capability for the associated application. This server may need the latest version of the application software loaded and the application data restored before it can be used for disaster recovery purposes.
Hot-Standby Server ? A server that is dedicated to providing DR capability for the associated application. This server is fully configured; the application software and data is kept in synchronized with production and server is able to take over production processing load with minimal manual intervention in the event of a disaster.
