    DPM 2012 SP1 Protecting Sharepoint using SQL 2012 Always On AG as backend is not currently supported.
    Mike Jacquet Microsoft employee

    When you try to protect a Windows SharePoint farm using SQL 2012 Always On AG backend using System Center Data Protection Manager 2012 Sp1, you receive one of the following error messages:

    ERROR
    =====
    DPM cannot protect this SharePoint farm because DPM did not detect any dependent databases to be protected. (ID: 32008) Verify that the appropriate SQL Server VSS writers are enabled on the computers hosting the SharePoint databases.


    This Windows SharePoint Services farm cannot be protected because DPM did not find any dependent databases and search indices to be protected. (ID: 32008) 1) Verify that the appropriate SQL Server VSS Writers on the computers hosting the Windows SharePoint Services databases are enabled. 2) Verify that the Windows SharePoint Services Search VSS Writers are enabled on the computers where the search indices are.

    CAUSE
    =====
    At this time using SQL 2012 availability groups (AG) for Sharepoint back end is not supported by DPM 2012 Sp1.  We will have some public facing content on the limitation shortly.  I cannot say at this time if this will be fixed in a future DPM 2012 rollup, it needs to be investigated by the product group.

    Creating and using certifcates for DPM tape backups.
    Mike Jacquet Microsoft employee

    Below are quick links for using certificates encrypting DPM tape backups for all versions of DPM.

    How to Create Self-Signed Certificates for Successful Encryptions
    http://technet.microsoft.com/en-us/library/ff399364.aspx

    MakeCert.exe is available as part of the Windows SDK, which you can download from one of the below links:

    http://go.microsoft.com/fwlink/p/?linkid=84091.
          http://msdn.microsoft.com/en-us/library/windows/desktop/aa386968(v=vs.85).aspx

    You can install Windows SDK and select option “Tools” under “.Net Development” and   unchecked everything else for installing makecert.exe only.

    How to Import Certificates into DPMBackupStore
    http://technet.microsoft.com/en-us/library/ff399563.aspx


    People who have to have deal with Real Certificate Authorities can use the following information to assist with their requests:
     
    If you are dealing with an organization that uses a Windows CA, have them issue a certificate based on the "Web Server" Template.
    If you are dealing with an organization that uses another vendors CA, request that they issue you a certificate with the following:
     
    Key Usages = Digital Signature, Non-Repudiation, Key Encipherment, Data Encipherment
    Extended Key Usage = Server Authentication
     
    The above match the values of your self generated certificate.

    DPM compatible Tape libraries
    Mike Jacquet Microsoft employee

    ·        The guidance we're giving customers is if the tape library or standalone tape drive is listed on the Windows server catalog under the hardware / storage section and shows compatible with Windows 2008  x64 or Windows 2012 X64, then it should work fine with DPM 2010 / 2012 / 2012 Sp1. 
    http://www.windowsservercatalog.com/

    Compatible tape libraries - Applies To: System Center 2012 - Data Protection Manager, System Center 2012 SP1 - Data Protection Manager
    http://technet.microsoft.com/en-us/library/hh916523.aspx


    Also leverage the DPM 2007 compatibility list, anything on this list should work on DPM2010 if they have Windows 2008 X64 drivers.

    System Center Data Protection Manager 2007 Tested Hardware
    http://technet.microsoft.com/en-us/dpm/cc678583.aspx

    If you cannot find support for the library, you can download and run the DPMtapeLibraryCompatibilityChecker tool from the following link.

    https://skydrive.live.com/?cid=885774776d4f197a&sc=documents&id=885774776D4F197A%21128


    For Standalone drive.
    =====================

    Run the following command to list libraries attached to the system.

    DPMLibraryTest.exe /Certify /LL


    Run the following command, where \\.\tape######## is the symbolic name of the tape drive to test from the output of the /LL command.


    DPMLibraryTest.exe /CERTIFY /TL \\.\Tape2147483646 /SA


    For tape library
    ================

    Run the following command to list the libraries attached to the system:

    DPMLibraryTest.exe /Certify /LL

    Run the following command, where \\.\Changer# is the symbolic name of the tape library to test from the output of the /LL command.

    DPMLibraryTest.exe /CERTIFY /TL \\.\Changer0 /ST 1 2 4 5

     

    Description of the tests.

    Test 1: Basic Configuration
    This test will scan your system for attached devices. It will identify the libraries and the stand-alone drives attached to your system and give you a summary of what it finds. For each device, you will see a Device Name, Serial Number, Vendor Name, Product Name, Firmware Revision and SCSI properties.
    At the end of this test, the user must verify whether all the information as seen by the tool. If the information is incorrect, check the following:
    • Check if all the devices are listed in Device Manager.
    • Ensure that the drivers for the devices are up-to-date.
    • If the drive mappings are incorrect, use the DPMDriveMapping.exe to correct the mappings. If you do not have DPM installed on the computer, copy the DPMLA.xml that DPMDriveMapping.exe creates to the folder to which you extracted the Tape Library Certification tool.

    Test 2: Mount/Dismount
    This test will pick a tape from the first available slot and perform a mount/dismount of that tape to/from a drive.

    Test3: Drive Cleaning
    A cleaner cartridge in needed for this test to run. Please read the pre-requisites section for this test. If you are using Firestreamer or a VTL where you cannot remove/change tapes, please use the /ST flag of the tool to skip the cleaner test.

    Test4: I/E Media
    This test will pick up the first available tape and move it to the I/E port and back. If your library/VTL does not have I/E ports the tool will automatically skip the test.

    Test5: I/O
    This test will pick up the first available writable tape and write a few buffers to it and try reading what is written. The purpose of this test is only to check for reading/writing ability.  Any specific/transient errors in any drive have to be inspected using the Advance Mode.
     Warning
    This test will overwrite information in the tape. Ensure that the first available tape does not have important data on it.

    Once complete, for any test failures, review the  LibraryTestTool-*-Curr.errlog files located in the directory you ran the tool from.

    Once the tool passes the tests, then DPM should be able to use the tape library for backups.

     


    NOTE1: DPM does not support Automated Cartridge System Library Software, ACSLS is the software that controls an Automated Cartridge System (ACS). There are no plans to support it.

    NOTE2:  DPM does not support tape libraries that have auto-clean feature enabled. If the library supports auto-clean but that feature cannot be disabled, wo do not recommend using that library with DPM.

    Windows 2012 server Hyper-V guests are placed in saved state during DPM backup.
    Mike Jacquet Microsoft employee

    You are using DPM 2010/2012/2012 Sp1 to backup Windows 2008 (R2) hyper-v guests and observe that Windows 2012 server / Windows 8 guest VM's only get the option "Backup using saved state". But you want to backup it using child partition snapshot.

    It was also reported that some Windows 2012 server guests transfer the whole VM during backups instead on block level changes.  The below resolves both of these issues.

    SOLUTION
    =======

    What we found is that the Hyper-V integration components needs to have scoped VSS snapshots to be turned off in order to support hot backups. This is a new feature apparently in Win8/2012 and the default is enabled.

    Implement this registry key on EACH VM that is Windows 8 or Windows 2012 to resolve the issue.  You must add a key called SystemRestore, then add a value called ScopeSnapshots as follows.

    HKLM\Software\Microsoft\Windows NT\CurrentVersion\SystemRestore
    REG_DWORD ScopeSnapshots 0x0

    See the additional info on scoped snapshots.

    DPM is performing "Backup Using Saved State" versus "Backup Using Child Partition" - WHY ?
    Mike Jacquet Microsoft employee

    When DPM protects a Hyper-V guest using HOST level protection, the Hyper-V writer on the hyper-V host communicates with the integration components inside the guest and determines if child partition or saved state backup will be performed.  Once DPM adds the guest to a protection group, the description: "Backup using child partition" or "backup using saved state" will not change, even thought the condition that determines the state may change.

    To get a real-time view of how then next backup will be perfomed, you can run the following test.

    To list hyper-V writer captions for guests to see if online or saved state backups can be done:

    From an administrative command prompt:

    a. Type: copy con script.txt and press enter
     b. Type: list writers and press enter
     c. Press CTRL + Z (to save)
     d. Type: diskshadow /s script.txt | find /i "caption: backup using"

    Output will be displayed for each guest.


    Here are the general conditions that make a VM go into a saved state during backup.

    Protecting Hyper-V machines
    http://technet.microsoft.com/en-us/library/hh757866.aspx


    Conditions when DPM fails to back up Hyper-V virtual machines in an online state

    By default, System Center 2012 – Data Protection Manager (DPM) performs a backup of a Hyper-V Virtual Machine (VM) in an online state. However, DPM cannot back up a Hyper-V VM in an online state, if one or more of the following conditions are true:

    •Backup (Volume Snapshot) Integration Service is disabled or not installed.
    •The virtual machine has one or more dynamic disks.
    •The virtual machine has one or more non-NTFS based volumes.
    •The virtual machine Cluster Resource Group in a cluster setup is offline.
    •The virtual machine is not in a running state.
    •A ShadowStorage assignment of a volume inside the virtual machine is explicitly set to a different volume other than itself.
    •An App-V drive is installed on the virtual machine that creates a non-NTFS volume.

    These conditions are set by the Hyper-V writer. In such a case, the VM is put in a saved state before a snapshot of host volumes are taken (except when the VM is turned off) for a backup. The Hyper-V writer adds the VM in the following format:
    •For offline backups: Backup Using Saved State\<VMName>
    •For online backups: Backup Using Child Partition Snapshot\<VMName>

    Additional reason is if there is less than 300MB free space on a volume in the guest.


    If you are using DPM 2010/2012/2012 Sp1 to backup Windows 2008 (R2) hyper-v guests you may observe that Windows 2012 server / Windows 8 guest VM's only get the option "Backup using saved state". It is also reported that some Windows 2012 server guests transfer the whole VM during backups instead on block level changes. 

    The below resolves both of these issues.

    SOLUTION
    =======

    The Windows 8 or Windows server 2012 guest needs to have scoped VSS snapshots turned off in order to support online backups. This is a new feature apparently in Win8/2012 and the default is enabled.

    Implement this registry key on EACH Windows 8 or Windows 2012 guest to resolve the issue.  You must add a key called SystemRestore, then add a value called ScopeSnapshots as follows.

    HKLM\Software\Microsoft\Windows NT\CurrentVersion\SystemRestore
    REG_DWORD ScopeSnapshots 0x0

    Anouncement: System Center Data Protection Manager CSV Serialization Tool
    Mike Jacquet Microsoft employee

    This tool will help serialize DPM backups across multiple Windows 2008 based hyper-v clusters in a unattended way.

    Download the tool from the below KB article.

    System Center Data Protection Manager CSV Serialization Tool
    http://www.microsoft.com/en-us/download/details.aspx?id=36524

    Overview

    With the current approach, if there are multiple clusters managed by DPM, the user needs to run DSConfig.ps1 on one node of each cluster and then XMLs of each cluster needs to be merged and replace the DataSources.xml in %ProgramFiles%\Microsoft System Center 2012\DPM\DPM\Config  directory of the DPM server. And moreover these steps need to be repeated each time any VM is added to the cluster.

    The XML merging/serialization tool will remove many of these manual steps. The tool needs to be run on the DPM server periodically (or scheduled). It will run DSconfig.ps1 on one node of each cluster, merge the XML and replace Datasources.xml in the DPM config directory. 

                                   

    System requirements

    Supported operating systems: Windows Server 2008, Windows Server 2008 R2, Windows Server 2008 R2 SP1
