Several questions around SCDPM... RRS feed

  • Question

  • Hi Forum,

    After reading the MS SCDPM 2012 supported and un-supported scenarios list.

    ...I have a few questions:

    1) Section:      SharePoint protection issues
       Statement:    AlwaysOn not supported
       Issue:        DPM can’t protected SharePoint farm SQL Server databases that have Always On enabled.
       Workaround:   None.
       Question:     What is the recommended method to protect SharePoint 2013 that resides upon MS SQL AlwaysOn ?

    2) Section:      SQL Server protection issues
       Statement:    AlwaysOn recovery to original location isn’t supported
       Issue:        When DPM is protecting SQL Server with AlwaysOn enabled data recovery to the original location isn’t supported.
       Workaround:   None.
       Question:     Can someone outline the recovery process for MS SQL AlwaysOn ?

    3) Section:      Hyper-V and virtual machine protection issues
       Statement:    DPM doesn’t support the backup of Hyper-V clusters in different domains
       Issue:        In order to backup Hyper-V server clusters they must be located in the same domain as the DPM server.
       Workaround:   None
       Question:     Does this refer to only the protection/backup of Hyper-V cluster members that are Hyper-V hosts, or...
                     does this also cover/include protection/backup of guest VMs on Hyper-V clusters from different domains?

    4) Statement:    Secondary DPM protection of a Hyper-V cluster isn’t supported for a scaled-out DPM server deployment
       Issue:        When protecting a Hyper-V cluster using scaled-out DPM protection, you can’t add secondary protection for the protected Hyper-V workloads.
       Workaround:   None
       Question:     What is 'scaled-out' DPM?

    5) Requirement:  I want to store backups of Hyper-V guests, and backups of MS SQL AlwaysOn on DPM de-duplicating storage.
       Question:     Is it possible to replicate this 'de-duplicated storage' from one DPM environment to another?

    6) Requirement:  I want to replicate DPM backups from primary to DR site via WAN.
       Question:     Does DPM implement any form of optimized replication post de-duplication?

    Thanks,
    Dave.

    1) Section:      SharePoint protection issues
       Statement:    AlwaysOn not supported
       Issue:        DPM can’t protected SharePoint farm SQL Server databases that have Always On enabled.
       Workaround:   None.
       Question:     What is the recommended method to protect SharePoint 2013 that resides upon MS SQL AlwaysOn ?

    ANSWER:  We are adding support for protecting Sharepoint utilizing SQL Always-on in a future DPM 2012 R2 update rollup UR.  In the meantime, you can protect the Sharepoint SQL databases using DPM SQL protection - however item level recovery will not be possible.

    2) Section:      SQL Server protection issues
       Statement:    AlwaysOn recovery to original location isn’t supported
       Issue:        When DPM is protecting SQL Server with AlwaysOn enabled data recovery to the original location isn’t supported.
       Workaround:   None.
       Question:     Can someone outline the recovery process for MS SQL AlwaysOn ?

    ANSWER: You can Recover the SQL databases to any non-SQL-Always on SQL Server, or restore the DB files to a volume on the SQL Server and replace the .mdf and .ldf files manually, or delete the always-on DB and restore back to original location.

    3) Section:      Hyper-V and virtual machine protection issues
       Statement:    DPM doesn’t support the backup of Hyper-V clusters in different domains
       Issue:        In order to backup Hyper-V server clusters they must be located in the same domain as the DPM server.
       Workaround:   None
       Question:     Does this refer to only the protection/backup of Hyper-V cluster members that are Hyper-V hosts, or...
                     does this also cover/include protection/backup of guest VMs on Hyper-V clusters from different domains?

    ANSWER: It refers to host level backup of guest VM's.

    4) Statement:    Secondary DPM protection of a Hyper-V cluster isn’t supported for a scaled-out DPM server deployment
       Issue:        When protecting a Hyper-V cluster using scaled-out DPM protection, you can’t add secondary protection for the protected Hyper-V workloads.
       Workaround:   None
       Question:     What is 'scaled-out' DPM?

    ANSWER:  Scale out refers to using multiple DPM servers to protect a large Hyper-V cluster.

    See this blog: http://blogs.technet.com/b/dpm/archive/2013/05/01/sc-2012-sp1-dpm-leveraging-dpm-scaleout-feature-to-protect-vms-deployed-on-a-big-cluster.aspx

    5) Requirement:  I want to store backups of Hyper-V guests, and backups of MS SQL AlwaysOn on DPM de-duplicating storage.
       Question:     Is it possible to replicate this 'de-duplicated storage' from one DPM environment to another?

    ANSWER: Dedupe is done by Windows against the .VHD files hosting the DPM storage pool, so it is not possible to replicate that to another DPM server.

    6) Requirement:  I want to replicate DPM backups from primary to DR site via WAN.
       Question:     Does DPM implement any form of optimized replication post de-duplication?

    ANSWER:  All secondary protection is optimized in that only block level changes are transmitted to the secondary DPM Server one initial replica is created. You can also enable on-wire compression to help further reduce data transfer size. Here again it can then utilize Windows Dedup against that DPM Servers storage pool .vhd files.

  • Hi,

    I can't say for sure, but I believe it's on the roadmap for UR5.... which should be released sometime in January 2015.

  • One last thing Mike, if I may...

    Are you able to roughly outline when the UR roll-up that supports DPM protection of SharePoint on MS SQL AlwaysOn will be released?

    Thanks. Dave.
