Provided are a method, system, deployment and program for managing data transfer in consistency group formation. In one embodiment, nodes are periodically polled to determine traffic conditions. An estimated drain time for a node such as the most congested node, for example, is compared to a drain time limit and if within a vicinity of the drain time limit, operations switch to a consistency group formation mode. Other embodiments are described and claimed.
