ASYNCHRONOUS PAUSING OF THE FORMATION OF CONSISTENCY GROUPS

摘要

Provided are a computer program product, system, and method for asynchronous pausing of the formation of consistency groups. A first copy operation is initiated to copy the source data from the first storage to the first data copy in the second storage. A second copy operation is initiated to copy the first data copy in the second storage to a second data copy in response to forming a consistency group of the source data at the first data copy forms consistent as of a point-in-time with respect to the source data. The first copy operation is suspended to allow for further processing of the first data copy in response to completing the second copy operation. The formation of a next consistency group is restarted between the source data and the first data copy in response to receiving a resume command.

主权项

1. A computer program product for copying source data in a first storage to a first data copy in a second storage, wherein the computer program product comprising a computer readable storage medium having computer readable program code embodied therein that executes to cause operations, the operations comprising:
initiating a first copy operation to copy the source data from the first storage to the first data copy in the second storage; initiating a second copy operation to copy the first data copy in the second storage to a second data copy in response to forming a consistency group of the source data at the first data copy forms consistent as of a point-in-time with respect to the source data; determining whether there is indication to pause forming consistency groups in response to completing the second copy operation; and initiating forming a next consistency group between the source data and the first data copy in response to determining that there is no indication to pause forming consistency groups.
