Creates Replicas for Disaster Recovery and Runs Recovery

Virtual Server DR is a service that quickly restores the system to normal operation when it is interrupted by various disaster situations and risk factors.
Users replicate Block Storage associated with Virtual Servers to a different region than the location they are using, perform mock drills to prepare for disaster situations, and execute actual recovery when a disaster occurs.

Overview
