Provided are a method, system, and article of manufacture, wherein a storage manager application implemented in a first computational device maintains a virtual logical volume that has a plurality of segments created by the storage manager application. At least one additional copy of at least one of the plurality of segments is maintained in at least one linear storage medium of a secondary storage. A request for data is received, at the first computational device, from a second computational device. At least one of the plurality of segments and the at least one additional copy are used to respond to the received request for data. |
