Summary:In one general embodiment, a computer-implemented method includes querying a database associated with a first cluster of a virtual tape library system for volumes of data stored in the first cluster and querying a second database associated with a second cluster of the virtual tape library system for volumes of data stored in the second cluster. Results of the querying of the database associated with the first cluster are compared with results of the querying of the database associated with the second cluster. The method further includes generating a list of entries of volumes of data that are to be migrated from the first cluster to the second cluster based on the comparing of the results. The entries of the list are ordered according to predefined conditions. The method further includes migrating from the first cluster to the second cluster, copies of the volumes of data of the generated list.
