    Hi all,

    I have connected a usb external drive as a backup to disk solution using Windows Backup feature on Windows Server 2008 R2 in a test environment to see if what the limitations are. After all my tests I've removed the test server and now I find that whenever I connect the usb drive it will not be read.
    I have tried deleting the volume, formatting the partition, nothing helps. After a lot of tests it got to a point where it would either show as RAW partition or simply as not initialized. I've worked with diskpart and with the GUI tools to try and make something of it but nothing worked.
    Most of the times I would get errors that the file specified does not exist and in event viewer I find the following errors:

    Event ID 140: The system failed to flush data to the transaction log. Corruption may occur in VolumeId: \\?\Volume{93c8cbc2-42fb-11e3-be75-5cac4cfd0b06}, DeviceName: \Device\HarddiskVolume5.

    (A device which does not exist was specified.)

    Oddly enough Volume 5 is on the internal Hard disk of the machine I'm using right now, not on the USB disk.

    Eent ID 153: The IO operation at logical block address 5f186f for Disk 1 was retried.

    After many different attempts I managed to get it to see the volume as it was named by the backup service again but I can't browse the files, nor can I reformat.
    Any ideas?

    I'm using Windows 2008 R2 Foundations and I'm running few roles on it (such as Active Directory etc.).

    I'm using Windows Server Backup to backup whole server ("Full server" option in dialog box) to backup NAS (network share folder). Backup is completed succesfully, but when i open this detail of backup I see only dashes (except status) by the Server-state and System recovery rows. Is that ok? I know that is probably silly question, but I want to be sure- I don't want to find out that my Active Directory database is not backuped :-)

      I have a Windows Server 2012 "host" server that is running Hyper-V. It is running two Hyper-V virtual machines, both also Windows 2012 servers. I am using the built in Windows Server Backup feature running on the host to backup these virtual machines to an NTFS formatted drive which the host connects to via iSCSI.

    If I select to backup just the virtual machines and host component using the "Hyper-V" selection in Windows Server Backup, then the backups are always full (i.e. not incremental), even when Windows Server Backup is configured for Faster Backup Performance.

    However, if I select to also backup the volume that the virtual machines are held on (i.e. backup the virtual hard disk files etc.), then that volume is backed up incrementally. Further to that, the Virtual Machine backups (as selected under the "Hyper-V" selection in Windows Server Backup) then happen almost instantly, I'm guessing because the files that comprise their backup (e.g. the virtual hard disk files and VM configuration files) have already been backed up. The summary of the backup job still reports that the backup type as full, but the amount of data transferred is 0kb. It reports a 56MB incremental backups for the D: volume that the Virtual Machines (VHDs and config files) are stored on. The log file for the backup just mentions that the backup of volume D: was successful, and states information about the application backup for the Virtual Machines.


    I guess, at the end of the day, I've just got two simple questions:

    1. Is it possible to do incremental backups of Hyper-V guests using the built in Windows Server 2012 backup feature by just selecting the Hyper-V component and the virtual machines when selecting what to backup?
    1. Is backing up the volumes the VMs are stored on in conjunction with selecting the VMs under Hyper-V in the backup selection an OK way to achieve incremental backups if 1 is not possible.


    Many thanks for any help anyone can provide.

    This is a problem which appears to have resurfaced after reportedly being fixed in Symantec. The Symantec support person asked that I post a question in Technet to see if we can get a quicker answer:

    Error in deletion of [C:\System Volume Information\EfaData\SYMEFA.DB] while pruning the target VHD: Error [0x80070020] The process cannot access the file because it is being used by another process.
    Application backup

       Component: 1F883BB7-A6AA-4130-AB7D-0849DBBE2D8C
       Caption     : Backup Using Saved State\VM-Test
       Logical Path: 

    I've installed Windows Server 2012 Standard on the host, and am backing up a W2K12 Virtual Machine. I have deleted the previous scheduled backup and then recreated a new backup with just one virtual machine. If I delete the W:\WindowsImageBackup sub-folder (I renamed the "live" sub-folder temporarily) the VM is backed up OK the first time. If I try to back up a second time, I get the pruning error.

    I have added the following exclusions:

    VM locations:

    VM Extensions:

    WSB drive:

    DPM 2012 exclusions:
    C:\Program Files\System Center 2012\DPM\DPM\bin\DPMRA.exe
    C:\Program Files\System Center 2012\DPM\DPM\Temp\MTA\*
    C:\Program Files\System Center 2012\DPM\DPM\XSD\*

    The DPM Services were disabled and stopped.

    AntiVirus: Symantec Endpoint Protection Small Business Edition Version 12.1.2100.2093
    (12.1-RU2-MP1) This version was supposed to have a fix for all this.
    Symantec re-installed this with me with only the "Virus and Spyware Protection" components included and double checked the exclusions list.
    Disabling Symantec is not enough - it has to be uninstalled in order for the backup to work again.

    The test virtual machine was stopped at the time of the backup and has one fixed size VHDx.

    The Symantec Support person was hoping someone from Microsoft might be able to advise if there were any other exclusions that could be considered.

    Strangely, this has been working fine for the past couple of weeks. It started acting up once I attempted backing up a VM with BitLocker encrypted VHDx's. (Not this test VM). Don't know if this was just a coincidence or if there is any connection. I have also been using Virtual Floppies, Differencing Disks, and Snapshots on other VMs.

    When watching Resource Monitor, during the backup, it looks like ALL the virtual machine VHDs are opened and at least partially read, even though they are not running and not included in the backup.

    Any suggestions would be helpful.

  • 11/10/13--11:48: Windows 2008 R2 image
  • Hi,

    I currently use Backup Exec Server System Recovery to image my Windows 2008 R2 servers for disaster recovery.  The restore with this product takes days because it NEVER works on the first try.  Does anyone know if Microsoft has a product I could use instead?  The Symantec Backup Exec people have a solution too called Simplified Disaster Recovery (SDR) with Backup Exec.  Does anyone use this product?  If yes how does it work?



    Thank You, Scott

    I have complete my setup of Windows 2012 Essential server and added several users /computers.  My users are setup for folder redirection under the GPO and have exclusive rights to their folders.  I have checked on their computers to verify files have now been copied to the serverfolders\folder redirection folder under their name.  After several backups using the server backup I tried to restored a test file and found no files have been backed up. Other files in the Company Share have been backed up and I can restore those.

    How do I backup and restore user files under the folder redirection folders if, as an administrator, I do not have access to them?

    How to fix the problem if in Active directory ntdc.dit is corrupted and the backup is also not taken.

    Can please someone help me to reslove this issue?

    Hi there!

    We use a powershell script where we make backup of Windows servers using Windows Server Backup tool.

    We ran this script:

    $day=(get-date -f dd-MM-yyyy)
    wbadmin start backup -allCritical -backupTarget:$backuplocation -include:d: -vssfull -quiet | Out-FileForce "$backuplog"

    Ok, in this case (depends on which day we set up backup thru Task Scheduler) we got backups in subfolders in\\networklocation and every time the backup is done it is done as full backup.
    Is there a way to achieve that incremental backups would be done in thoose subfolders.

    As far as I have read info about making backups using Windows Server Backup you are able to do incremental backups but only if you do it every time in the same folder and not making any subfolders for different days.
    Is my understanding right?
    But if that's thru, that would make a corruption of a backup if sth goes wrong and it owerwrites that one and only folder for backups. In other words if you don't make subfolders for backups and you retain only one folder for it,
    that one-time when backup would partly do it's job it would corrupt the data in backup folder?
    Soo is there a way to achieve incremental backups in this scenario?

    The system is a Dell R720 running Microsoft Server 2012 with Hyper-V.  The backup is configured to run every night at 2:30AM and backup the System state, 2 VMs and Host Component.  Every other night the backups complete with a warning.

    Time            Message          Description
    11/12/2013  2:30 AM       Backup        Successful

    11/9/2013    2:30 AM       Backup        Completed with warnings

    When I check the details for the Completed with warnings, the System State Backup did not complete.  When viewing the list of all backed up files it stops at the same point for the System State Backup.  The error message is:
           System state           The operation ended before completion.  Detailed  error: The process cannot access the file because
                                         it is being used by another process.

    The event log has the following Warning messages:

    I have tried changing the backup time to a later time and deleted the backup schedule and re-entered it.

    I have been searching the forums but nothing seems to be related to my situation.

    Any help would be greatly appreciated as the server is already in production.

    When I try to run a backup it gets stuck at files found. The image below shows my problem. I have tried uninstalling and reinstalling Windows server Backup, and I still have the same issue. This server is a virtual machine running in virtualbox. I had an enumeration failed error before and fixed this by running this Get Invalid Paths script that I found on a technet blog. I am now stuck with wbadmin not moving from "found <70487> files". Any suggestions would be greatly appreciated.

    The VSS service was set to manual so I set it to automatic and force started it.

    It keeps shutting back off and my backups are failing.

    I tried this. see below but it still won't work

    see below

    Re-register the VSS components see below

    Sometimes re-registering VSS core components can fix errors. Copy the
    following commands to Notepad and save the file with a ‘.bat’ extension. Run the
    .bat file by opening a command prompt and entering the .bat file name.

    cd /d %windir%\system32
    net stop vss
    net stop swprv
    regsvr32 /s
    regsvr32 /s oleaut32.dll
    regsvr32 /s vss_ps.dll
    regsvr32 /s /i swprv.dll
    regsvr32 /s /i eventcls.dll
    /s es.dll
    regsvr32 /s stdprov.dll
    regsvr32 /s vssui.dll
    regsvr32 /s
    regsvr32 /s msxml3.dll
    regsvr32 /s msxml4.dll
    net start swprv
    net start vss

    I've also tried setting the volume shadow copy service to auto because it was
    set to manual and force started it and the backup failed anyway

    Good evening,

    I have 2 drives on my computer. In one of them I have the System Restore Image. Also created a recovery disk so you can restore if your computer has a problem more serious.
    I already ran the recovery disk but does not appear to me nothing that I can say that the image you want to use is on disk D:

    Anyone know how I can do this?

    Best Regards

    I have issues with transportable snapshot and iscsi target, i can't "mount" the snapshot.

    My configuration:
    -the first server have iscsi target server and backup software (CA arcserve)
    -the second server have hyper-v with iscsi volume (from the first server) which host vhdx files.
    Both server are windows server 2012R2 up to date, iSCSI Target VSS hardware provider installed and credential OK.

    What i'm trying is to backup VM vhdx offhost with transportable snapshot.

    Transportable snapshot creation works fine (with diskshadow.exe or arcserve via vss writer).
    I can see the shadow copy on iscsi server ("list shadows all" from diskshadow.exe) and one iscsi snapshot (get-iscsivirtualdisksnapshot)
    But the iscsiservertarget can find the shadow copy. I have event id 12362 and 12293.
    Here's an example of Get-IscsiServerTarget | Format-Custom lunmappings

    class IscsiServerTarget
      LunMappings =
          class LunMapping
            TargetName = tom-hyperv
            Path = D:\iSCSIVirtualDisks\tom-hyperv.vhdx
            Lun = 0
          class LunMapping
            TargetName = tom-hyperv
            Path = \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy{D0BF0F58-4DDA-11E3-80C9-002590D672D5}\iSCSIVirtualDisks\t
            Lun = 1

    You can see the vhdx associated with iscsi target, and the shadow copy it tried to mount.

    I have try to mount iscsi target on iscsi server, and try with disk offline or online. But mounting iscsi target on two server at the same time may corrupt the filesytem (isn't it ?).

    I have contacted CA arcserve support, but they think it's a windows related issue.
    Thanks for your help.

    I am trying a full bare metal restore job of my SBS 2008 server using Microsoft Windows Server backup. This restore is to identical hardware including identical drives and RAID configuration. (HP Proliant DL180) 

    The backup has been running on the live server for months to a permanently connected USB drive. In a n average week (5 days) it will fail around 3 times. I have tried to resolve this but never found the cause. Some complete successful and as long as I can get the main server back up and running even if its a few days out of date I don't mind that. 

    If I look in Server Backup for the last week it looks like this: 

    18/11/2013 00:00 - Backup Successful

    17/11/2013 00:00 - Backup Failed

    16/11/2013 00:00 - Backup Succesful

    15/11/2013 00:00 - Backup Successul

    14/11/2013 00:00 - Backup Failed

    If I click on View Details under All Backups I can see the ones that completed successfully (so the 18/16/15 November) 

    I disconnected the drive, connected to the test server and booted from the 2008 SBS DVD. Upon boot up I selected the option to Repair and then restore. 

    The server sees the drive but for some reason it only lists dates that the job failed as the possible selection of dates to restore from. The 18/16/15 November and no where to be seen. Obviously selecting any other day and the job just fails. 

    Server Backup on the live server is saying that there is nothing wrong. I wondered if anyone might know if I am missing something. 

    Any help would be appreciated. 

    I am in the process of running a full backup to a network share to see if that works but I really wanted to be able to test the restore from USB.

    I need to write a hardware provider for VSS, Volume shadow copy service.  The target is 2008R2 but I would be happy with info to target any OS version.

    I've seen many write-ups on the flow and half pages on registering a provider.  What I am looking for is coding info and if possible an example in C++ or any .Net language.

    If anyone can point me in the  right direction, I would be very happy.

    We have several smaller to midsized customers that have invested money in tape drives and tapes. They are using Symantec BackupExec on Server 2003 / 2008 and 2008 R2. Unfortunately, Symantec postponed Server 2012 support in their products  many times already. This fact costs us many business opportunities to upgrade infrastructures to Server 2012.

    DPM 2012 is good for larger customers, but less suited for smaller companies (and the DPM "philosophy change" of the backup procedures, compared to older tape based backup solutions is an obstacle as well.)

    So we are looking for EASY backup solutions that support tape drives and server 2012. The "perfect" product for us would be just a tape driver and an extension to the integrated Windows Server Backup that would allow to store backups on tapes, the same way that Windows Backup allows backups to network shared folders.

    Does anyone knows EASY backup software that provides this functionality? I'm also very interested in feedback from peoples that have successfully used such products on Server 2012 and are satisfied with them.

    Thank you all in advance for any help.

    I have gone through the other posts with this error and non of the solutions offered has worked for me.

    I have recently attached a network storage device ( a DROBO which is Linux based).  I am doing backups to this device of all of my servers.  I have a share set up that the servers can connect to on the DROBO.

    I have scheduled backups on my servers to run at different times when my business is closed.  The two domain controllers execute the backup with no problem.

    The problem is on the domain member servers.  The backup will run if I run it from the Server backup utility, with the parameter to back up once using the scheduled backup options.  However, it will not run as scheduled.  I have found the following error in the task scheduler - Logon failure: the user has not been granted the requested logon type at this computer. (Exception from HRESULT: 0x80070569).  When I am at the backup snap-in, it does not show that the backup that was supposed to run the previous day was run, but does show that the scheduled backup has been incremented to the next day.

    I am running the backup under the domain administrators account and so there should be no problems with permissions.
