System, method and computer program product to automatically select target volumes for a fast copy to optimize performance and availability
First Claim
1. A computer program product embodied on or in a computer readable media for causing a computer to execute program instructions that result in the computer executing a method of performing a backup of data, the method comprising:
- in response to detecting that a fast copy function has been invoked, automatically selecting at least one target volume for writing fast copy-related data, the at least one target volume being selected for optimizing fast copy performance; and
writing the fast copy data to the selected at least one target volume.

Abstract
A computer-implemented method includes, in response to detecting that a fast copy function has been invoked, automatically selecting at least one target volume for writing fast copy-related data, where the at least one target volume is selected for optimizing fast copy performance, and writing the fast copy data to the selected at least one target volume. Also disclosed is a data processing system having circuitry that operates in accordance with the method, as well as a computer program product, embodied on a computer readable media, that implements the method.

26. A data processing system comprising at least one host coupled through a bus to a data storage system, said at least one host comprising selection means, responsive to a detection that a fast copy function has been invoked, for automatically selecting at least one target volume from a list of available target volumes, the list being received through said bus, for writing fast copy-related data, the at least one target volume being selected by the selection means in accordance with at least one performance-related criterion and at least one reliability-related criterion;
- said data storage subsystem comprising means for writing the fast copy data to the selected at least one target volume.
