1. A method for enabling deduplication of a data file at each of a source and a target location in a distributed storage management system, the storage management system containing a source computing system connected to a target computing system and a target data store located within the target computing system, the method comprising:

  • maintaining a shared index for tracking deduplicated data chunks stored within the target data store;

    providing a deduplication process for deduplication of data chunks to be stored in deduplicated form within the target data store;

    enabling execution of deduplication instructions by the target computing system and execution of deduplication instructions by the source computing system;

    deduplicating a data file into a set of deduplicated data chunks with use of the deduplication process, the deduplication process comprising a set of deduplication instructions executed by either of the source computing system or the target computing system;

    storing the set of deduplicated data chunks within the target data store; and

    updating deduplication information for the set of deduplicated data chunks within the shared index.
