摘要：
A primary data mover monitors both consistency time and idle time in a system that performs continuous, asynchronous, extended remote copying between primary and remote processors, and manages both with accuracy and consistency. The primary data mover detects system activity levels and manages data accuracy for the extended remote copying in both active and idle systems.
