Optimized Duplication?

Just wondering if anyone knows if the 5200 provides duplication of the deduped data between other 5200's (a.k.a. optimized duplication).

    Just to put things in perspective I would like to interpret the original question. 

    The fact that the post had 'optimized duplication' and the question was if it is possible to duplicate from one NB5200 to another, the answer is 'yes'. Hence GMAN63 wasn't wrong. 

    You can do optimized duplications as follows.

        MSDP to MSDP

        MSDP to PDDO (PureDisk acting as a storage server for NetBackup)

     

    Here MSDP can be on a media server or media server appliance like NB5200

    PDDO can be a PureDisk storage pool or an PureDisk based appliance like NB5000, NB5020 etc. 

    Hi bartman10,

      You are right in stating that MSDP cannot do deduplication across media servers. They are indeed dedupe islands. However GMAN63 answer to the question of optimized duplication from one NB5200 to another was also indeed correct.

      For a scalable global dedupe solution you need NB5000s or NB5020s. NB5200s are suitable as media servers in data centers. They can also function as a media server with dedupe for remote office use cases where the data from remote clients are backed up and deduped. Later they can be replicated (optimized duplication) to central data center which would be hosting a global dedupe pool based on NB50x0. This design uses less bandwidth as just the unique data is sent over WAN to central data center. You get local restores using the low retention images on NB5200, long term images are restored from NB50x0 over WAN. This design also makes the images at the central data center a DR hub for remote sites. 

    Warm regards,
