Abstract

A computer-implemented method according to one embodiment includes determining that a consistency group has not been created within a predetermined period of time; sending a request to create the consistency group, where the request includes an indication that a creation of the consistency group is mandatory; identifying one or more logical storage volumes associated with the request to create the consistency group; marking each of the identified one or more logical storage volumes to indicate that a point-in-time snapshot copy operation is not allowed for the one or more logical storage volumes; creating the consistency group; sending the consistency group from a source site to a destination site; and removing the marking from each of the identified one or more logical storage volumes to indicate that a point-in-time snapshot copy operation is allowed for the one or more logical storage volumes.

Description

BACKGROUND[0001]The present invention relates to data replication, and more particularly, this invention relates to throttling a point-in-time snapshot copy operation within a data replication environment.[0002]Data replication is a popular way of securing important data to provide protection against system outages. Performing a point-in-time snapshot copy of data also preserves a current state of data within a system. However, performing a point-in-time snapshot copy of data within a data replication environment affects a consistent asynchronous replication application. Further, too many consecutive point-in-time snapshot copies may affect a recovery point objective (RPO) of a system.BRIEF SUMMARY[0003]A computer-implemented method according to one embodiment includes determining, by a master process, that a consistency group has not been created by a data consistency application within a predetermined period of time; sending, by the master process to a subordinate process, a reque...
