Patent ID: 7877544

Claim:
A method, comprising: maintaining, by a storage manager application implemented in a first computational device, a virtual logical volume having a plurality of segments created by the storage manager application, wherein the plurality of segments of the virtual logical volume have been stored in a secondary storage by distributing the plurality of segments in at least three linear storage mediums; maintaining, in at least one of the at least three linear storage mediums of the secondary storage, at least one additional copy of at least one of the stored plurality of segments; receiving a request for data to recall all of the plurality of segments of the virtual logical volume, at the first computational device, from a second computational device; and in response to receiving the request for data, mounting two of the at least three linear storage mediums, and subsequent to the mounting using at least one of the stored plurality of segments and the at least one additional copy to respond to the received request for data to recall all of the plurality of segments of the virtual logical volume.
