In response to determining that one or more of the clusters in the first tier are designated as a copy target location, for each of the one or more clusters designated as a copy target location: a determination is made as to whether the given cluster is coupled to the secondary storage. Moreover, in response to determining that the given cluster is not coupled to the secondary storage, a copy of the volume is sent to the given cluster.
