Each read operation is delegated to each of its respective plurality of media servers until one of the respective plurality of media servers is available. The backup data specified by each read operation is read by the one media server of the respective plurality of media servers that is available. Each read operation may comprise a backup restoration, backup duplication, backup verification, or synthetic backup operation. Read operations can be targeted to a first and second plurality of media servers, which may be mutually exclusive. The archival storage system can be a tape storage system.
