EXECUTION OF POINT-IN-TIME COPY OPERATIONS IN CONTINUOUS MIRRORING ENVIRONMENTS |
摘要 |
Provided are a method, system, computer program product, and method for deploying computing infrastructure wherein a point-in-time copy operation command for a point-in-time copy of a point-in-time source volume to a point-in-time target volume is received while performing continuous copy operations from continuous copy source volumes to continuous copy target volumes. A determination is made as to whether the point-in-time target volume is a first continuous copy source volume and whether the point-in-time source volume is a second continuous copy source volume. A determination is made of metadata corresponding to the point-in-time copy operation, in response to determining that the point-in-time target volume is the first continuous copy source volume and the point-in-time source volume is the second continuous copy source volume. Point-in-time copy operations are performed on the continuous copy target volumes based on the determined metadata to execute the point-in-time copy operation command while performing the continuous copy operations.
