Disclosed are a method and system for pairing objects for the purpose of copying data. The method comprises the steps of selecting such pairs in a single view including graphical depictions of representations of storage resources, and implementing checks and alert messages regarding such pairings based on predefined rules. Preferably, these graphical depictions are side-by-side depictions in the single view of a logical configuration of the storage resources, and, for example, these depictions may be hierarchical trees. Preferably, users are able to select a single source and target volume and/or to select blocks of source and target volumes using familiar computer controls, and users may also confirm their selections before committing to them. These volumes may be in the same or different storage subsystems. In addition, some error checking and/or error handling, with an appropriate error message is preferably built into the tool of this invention.
