Abstract
Provided is a method, system, and an article of manufacture for maintaining data accessible by a host in two storage devices, wherein the data is comprised of a plurality of data sets. A determination is made of a percentage of uncopied data at the first storage device, wherein uncopied data comprises data sets to be copied from the first storage device to the second storage device. If the calculated percentage is greater than a threshold amount, a rate at which uncopied data sets are transferred from the first storage device to the second storage device is increased.
