Hyper-V CSV protection with DPM 2010

  DPM design for Hyper-V :

  •  Incremental Backups Only – full only once
  •  No More Backup Window – online backups
  • Application consistency via VSS
  • Protect Live Migration VMs in CSV clusters
  • Protect whole VM, recover individual items
  • Auto Protection of new VMs
  • Routine backups – nightly or more frequently

Strategy to Deply DPM 2010 in Hyper-V/CSV environment :

1. Plan:

  • Identify Project Requirements and scope
  • Simulate using Hyper-V Calculator
  • Review Hyper-V design guidelines & Best Practices
  • Acquire VSS Hardware Provider & check environment with SDPM SAN Testing Tool:
  • Validate a Pilot Environment
  • Ready for Deployment
    • Integration components should be updated on both VMs.
    • Ensure that Live Migration is functional

  2. Deploy : Protected CSV server

  • Install all recommended prerequisites:
General Prerequisite Install the integration components on the guests. For more information, see Install a Guest Operating System (http://go.microsoft.com/fwlink/?LinkId=165041).
Microsoft Windows Server 2008 SP2 Install Microsoft Windows Server 2008 SP2 OR Install the Microsoft Hyper-V prerequisites (http://go.microsoft.com/fwlink/?LinkID=133781).
Microsoft Windows Server 2008 R2 Install the following on the host computer:KB975354 (http://support.microsoft.com/kb/975354)KB975921 (http://support.microsoft.com/kb/975921)
  • Failover Cluster Validation
  • Enable Automount : Enable Auto mount on the host for successful child partition backups :  MOUNTVOL /E
  • Install Hardware Provider:Ensure that VSS hardware providers are installed : vssadmin list providers
  • Validate Hardware snapshots
  • Use DSConfig Tool to serialize backups (for software snapshots providers only) : 
    ·   Problem:With software snapshots, simultaneous triggering of VM backups (especially scale deployments) will cause backup jobs to time out and fail.
    ·   Enable Per CSV LUN Serialization:This serialization limits the number of virtual machine backups happening on a single CSV LUN.Create a DataSourceGroups.xml file by running the DSConfig.ps1 script on any one node of a cluster containing CSV.Place the file in the DPM server at %PROGRAMFILES%\Microsoft DPM\DPM\Config.Repeat step 1 for every cluster that is protected by a DPM server.The DataSourceGroups.xml file needs to be updated only when virtual machines are added, deleted, or modified in the cluster and protection is configured for them.

 3. Deploy  : DPM 2010 server

  • Enable Hyper-V Role on DPM Server :DPM supports item-level recovery (ILR), which allows you to do granular recovery of files, folders, volumes, and virtual hard disks (VHDs) from a host-level backup of Hyper-V virtual machines to a network share or a volume on a DPM protected server. You must have the Hyper-V role enabled on the DPM server to perform item-level recoveries. During item-level recovery, DPM has to mount the VHDs of the protected virtual machines
  • Install DPM server pre-requisites
  • Install DPM 2010
  • Turn off “TCP Chimney offload”For better throughput, TCP Chimney Offload should be turned off.
  • Allocate Storage Pool & Deploy Agents
  • Datasourcegroups.xml file:
    • Merge the DatasourceGroups.XML file for all CSVs protected by DPM server. This is applicable when software providers are used on the CSV cluster.
    •  Copy the <Group> tags from all the DataSourceGroup.xml files generated and add the text between the <DataSourceGroup> tags. The DataSourceGroups.xml file will now contain one <header> tag, one <DataSourceGroup> tag, and <Group> tags from all CSV clusters.
