  • Hi,

    Yes, the smallest protectable object on a volume is a folder.  When on the disk allocation screen, click the MODIFY buton, then the calculate link and DPM will calculate the size of the protected folder and adjust the size of the replica and recovery point volumes accordingly.

  • Thanks for the useful information. Can you confirm that DPM2010 support the deduplication technology?

  • Hi,

     

    DPM does not do software dedupe on the storage pool. Hardware de-dupe solutions can be used to shrink the storage footprint for DPM.  Virtual tape libraries from Data Domain (EMC) and Quantum can be used to de-dupe long term backups.  In addition, the short term (on disk) retention can be decreased if the VTLs are used more frequently.  For instance, if they are saving 30 days in the DPM storage pool, they could shrink that to 15 days and write out more frequently to the VTL.

    Another good option is the Netapp storage arrays which include de-dupe.  This storage can be used by DPM directly for short term retention.  If you a large enough size to warrant a storage array, regardless of de-dupe support, I would recommend looking at using thin provisioning to save space.

     

    DPM team has been working on multiple fronts to provide Dedupe solution for its customers.  As a priority, DPM 2012 has partnered with the following two hardware DeDupe Providers. 

    BitWackr:  
    BitWackr is a Dedupe controller from exar.com and is compatible with Microsoft applications as mentioned in http://www.exar.com/Common/Content/Default.aspx?id=7472

    Also BridgeStor has a DPM appliance with Dedupe built-in support that uses BitWackr in its appliance.  White paper and other information can be located in the below mentioned location.
