difference between duplication and deduplication?

difference between duplication and deduplication?

  • What do you mean?

    The "Backup" will always be 500GB - what is stored on disk will vary according to the deduplication obtained (we have been using 10GB as an example) - the tape copy will always be 500GB

    When the data goes from disk to tape it is re-hydrated (or uncompressed if you like) back to be 500GB on tape

    Really do not know what you are asking now
