DPM 2012 R2 - Exchange 2013 on Hyper-V 2012 R2- Agent level backup of Complete Server vs VM level backup RRS feed

  • คำถาม

  • Hi -

    Environment is DPM 2012 R2, Exchange 2013 DAG (2 server VMs on running in Windows 2012 R2 VM, hosts are Windows 2012 R2 with Hyper-V role)

    I have an existing Exchange DAG Protection Group backing up as follows:

    EXISTING DAG Protection group backup job settings (Agent level backup inside the VMs for both DAG members). This job backs up ONLY the exchange database (no volumes, system state or BMR):

    Short term recovery: 15 Days, 30 minutes synchronization

    Performance Optimization: Compression disabled, Consistency check: Automatic, Express Full Backup – 12:30 PM, 8:30 PM everyday

    Which of the following two alternatives to backup the rest of the server would be preferred? The above job will stay in place.

    ALTERNATIVE A - Backup rest of VM at the Hyper-V host
    Add a registry key to the Exchange VM and reboot:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtualization\VssRequestor Set Value to 1 for NO TRUNCATE
    Create a new Protection Group backing up the entire VM from the Hyper-v Host with no exclusions
    It is hoped that this backup will not interfere with the above existing Exchange DAG job or corrupt the database

    ALTERNATIVE B - Backup rest of VM with the agent in the Exchange VM
    Create a new PG that backs up all volumes on the VM, as well as System State and BMR
    Would I need to exclude any Exchange edb or log files or is DPM smart enough to not interfere with these

    Neither A nor B would do an Express Full at the same time as the Existing DAG job.


    Thanks!
