Protecting Mirrored Databases with DPM 2010 RRS feed

  • Question

  • I am reading the following article

    http://blogs.technet.com/b/askcore/archive/2009/04/24/protecting-mirrored-databases-with-dpm-2007-sp1.aspx

    The confusion is arising from the following lines

     

    1. DPM will not be able to create a Recovery Point until you stabilize the data source because DPM will detect the change in state

     

    What is meant by stabilizing the data source?

     

    2. Anytime a database goes from non-mirrored to mirrored or vice versa, the data source will need to be removed and added to the protection group again.

     

    Why would the database no from non-mirroed to mirrored or vice versa??? i think the database can go from being a primary and mirror state (failover) but failover between nodes doesn't mean that it is going from non-mirrored to mirror state. Does the article suggest that I have to re-create the protection group everytime there is a failover?

  • Hi
    (1) stablize here means completed consistency check.
    This is needed because DPM now protects a different physical copy.

    (2) No
    If you no longer mirror a protected database or you start to mirror a protected database, only then it needs to be removed and recreated in order to process the neccessary changes.
