1. A method of controlling computing devices in a data storage system, the method comprising: directing with a first storage computing system comprising one or more computing devices comprising computer hardware, a second storage computing system comprising one or more computing devices comprising computer hardware, to perform or initiate a first storage operation in which at least a portion of primary data stored on at least a first storage resource is copied to secondary data stored on at least a second storage resource, wherein the first and second storage computing systems are arranged in a hierarchy, and wherein the second storage computing system identifies the second storage resource with a first identifier; sending from the second storage computing system to the first storage computing system the first identifier associated with the second storage resource; directing a third storage computing system comprising one or more computing device comprising computer hardware to perform or initiate a second storage operation in which at least a portion of primary data stored on at least a third storage resource is copied to secondary data stored on at least the second storage resource, wherein the first and third storage computing systems are arranged in a hierarchy, and wherein the third storage computing system identifies the second storage resource with a second identifier; sending from the third storage computing system to the first storage computing system the second identifier associated with the second storage resource; determining with the first storage computing system that the first identifier and the second identifier are both associated with the second storage resource; and generating, with a computing device comprising computer hardware, display data usable to generate a graphical user interface including graphical information representative of storage operations associated with the second storage computing system and storage operations associated with the third storage computing system, the display data generated based at least in part on completion of the first and second storage operations.
