Extended remote copy configurator of three-site data replication for disaster recovery
Configuration and replication can be managed across multiple sites for datacenter volumes. A visual representation of a current configuration for a first of a plurality of replication techniques can be conveyed for display on a display device. Changes can be made to the current configuration, producing a future configuration. The future configuration can be analyzed for replication errors, and an updated visual representation can be produced that identified discovered replication errors and highlights differences between the current configuration and the future configuration. The updated visual representation can be conveyed, for display on a display device.

receive a change to the current configuration, wherein the current configuration and the change are included in a future configuration;
analyze the future configuration for a replication error;
generate an updated visual representation that identifies the replication error; and
transmit data associated with the updated visual representation.
2. The system of claim 1 , wherein the instructions further cause the processor to output the future configuration to a file for use in directing performance of a replication system in response to a request received by way of the visual representation.

6. The system of claim 5 , wherein the replication error is a lack of replication of a volume.
7. The system of claim 1 , wherein the change is associated with a copy of one or more volumes including non-critical data that is not continuously copied.
