THROTTLING A POINT-IN-TIME SNAPSHOT COPY OPERATION WITHIN A DATA CONSISTENCY APPLICATION

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.
