Abstract
An apparatus comprises at least one processing device that includes a processor coupled to a memory. The processing device is configured to maintain for a first storage server one or more index tables characterizing data backed up from the first storage server to at least a second storage server, to receive a request to back up a particular data item from the first storage server to the second storage server, to access, responsive to the received request, a corresponding one of the one or more index tables characterizing data backed up from the first storage server to at least the second storage server, and to control backup of the particular data item based at least in part on one or more entries of the corresponding one of the one or more index tables. Backup of the particular data item is illustratively controlled using content-based identifiers in the corresponding index table.
