Abstract
A data transfer application implemented in a computational device receives a request to copy a plurality of storage volumes that form a consistency group. A determination is made that a first storage volume of the plurality of storage volumes is more likely to be written into than a second storage volume of the plurality of storage volumes, in response to receiving the request to copy the plurality of storage volumes. The first storage volume is copied before copying the second storage volume, in response to determining that the first storage volume is more likely to be written into than the second storage volume.
