Abstract:
1. A method of creating indexes of secondary copies of data, the method comprising; copying primary data stored in one or more primary storage devices to one or more secondary storage devices, wherein copying the primary data to the secondary storage device creates a secondary copy on the one or more secondary storage devices; indexing a first portion of the secondary copy with a first index server, wherein indexing the first portion of the secondary copy creates a first index of the first portion of secondary data; indexing a second portion of the secondary copy with a second index server, wherein indexing the second portion of secondary copy creates a second index of the second portion of secondary data; copying the first index to the second index server so that the first index is available at both the first and second index servers; identifying that a plurality of requests for secondary data are associated with the first index; and distributing the plurality of requests for the secondary data associated with the first index among the first and second index servers to lessen a load on the first index server.
