  • Hi Khalil,

     

    Based on the research, the error message may be related to the Backup application that is running on the problematic server.

     

    Would you please check if Windows Server Backup feature is being used to take backup on the box? Or do you use any third party software application to make backup on the problematic server?

     

    The VSS event ID 12289 may occurs if the third party backup application is used. If possible, we would like suggest that you use Windows Server Backup which is a built-in feature on Windows Server 2008 to take backups.

  • We're seeing the same error, and we're using Windows Server Backup on a Windows 2008 x64 machine.  Every night at 9 PM (when backups start), I get 40 of these. Appears to be 8 different Writer Names (Registry Writer, IIS Config Writer, ASR Writer, COM+ REGDB Writer, WMI Writer, SqlServerWriter, System Writer, Shadow Copy Optimization Writer) happening 5 times before it gives up. Backups consequently fails with the following error:

    The disk used for backups is full. Could this be the reason for the failure? Shouldn't the backup software overwrite the older backup sets?

  • I am going to answer my own question:

    MS KB959962

    http://support.microsoft.com/kb/959962

    I installed this last night, rebooted and my backup worked without any errors.

    We're seeing the same issue on Windows 2008 Standard 64bit sp2. Would anyone have any ideas? We are using Windows Backup.

  • Hi LMHansen, can you install this hotfix withouth HyperV installed? I tried to install it but says the software version is incompatible. I am using windows 2008 on vmware
    Thursday, July 29, 2010 10:15 PM
  • Did you have HyperV installed? I don't use HyperV and this is complaining that the update does not apply to my system.

    I tried to install the 959962 but there is no hotfix available for server 2008 64bit.  

    any idea?

  • We got this problem lately on 2008 Std and SBS as well.

     

    I've got a hunch that this has got to do with storage volumes being dedicated to Windows Server Backup. These volumes always show up as 100% Used Space in Explorer but you can't browse them since they are dedicated to Server Backup I guess. So the VSS service can't maintain its regular shadowing since the volume appears to be full. If you use vssadmin to list the ShadowStorage you get something like this:

    Shadow Copy Storage association
       For volume: (\\?\Volume{260cc23f-baa3-11df-9f2f-0026b9677f3c}\)\\?\Volume{260cc23f-baa3-1
       Shadow Copy Storage volume: (\\?\Volume{260cc23f-baa3-11df-9f2f-0026b9677f3c}\)\\?\Volume
    6b9677f3c}\
       Used Shadow Copy Storage space: 71.87 GB
       Allocated Shadow Copy Storage space: 74.792 GB
       Maximum Shadow Copy Storage space: UNBOUNDED

     

    As you can see, these volumes got a '?' instead of volume letter. Also the Maximum Storage Space seems to be set to UNBOUNDED by default. 

     

    My guess is that these error messages can be ignored as the backup is obviously working. A fix from Microsoft would be appreciated though.

  • I'm getting the same errors, running Win2k8 Standard x86.  I noticed the task scheduler has a job for ShadowCopy which was enabled.  Will see if disabling resolves it...

    We are using CA Arcserve backup on this server.

  • Hi All .....

    I'm having the same error ......

    Windows 2008 Std which is in a VMware Environment.

    We use Veritas Netbackup for our prefered backup solution.

    I saw the link above but it says its actually for VISTA ? Might just be poor naming ?

    Anyway any FIXES on the way ???

  • Hi all,

     

    same error, using dpm 2010 on our backup server to backup the domaincontroller. getting this failure, sometimes it works sometimes not

     

    Maximum supported sessions: 64
       Completed sessions: 8
       Active sessions: 64
       Aborted sessions: 0
       Writer failed sessions: 3

     

    the hotfix is explained for hyper-v machines, we ware using esx

     

    any ideas? when i make a new protection group and delete the old backups it works for a one or two weeks, then the same error comes again, on the harddisk is enough free space

  • Don, same things here on our little SBS2k8 server. Backup completes eventually and seems to be ok. But errors related to back up make my eyeballs itch. Really would like to see a fix for this...

  • Hi James! Good to know we're not alone :) It's been a while since I looked into this and I'm currently working on another site so don't know if this is still an issue. My guess is that it remains though. Someone mentioned trying to disable VSS on problematic volumes (i.e. the WSB storage volume). I don't recall trying that but it sure would be worth a try. NB! As I see it the problem here being VSS trying to operate on the WSB storage volumes, not the volumes actually being backed up!! Kind regards, Don

  • Seems to be getting worse on our server... I'm seeing more errors, more often, and now I get random failures: 2720, 6772, 27745, and 3760 from SharePoint (which we don't really use.

    I also have been getting this DCOM error which appears to be related to VSS:
    Error Event ID: 10010, Source: DistributedCOM, "The server {0B5A2C52-3EB9-470A-96E2-6C6D4570E40F} did not register with DCOM within the required timeout." The class ID is for VssSnapshotMgmt  Many people have encountered this error:

    Don, can you check your logs and see if you have the same DCOM error?

  • Our error is certainly related to backup. I get a batch of this error every time the backup starts and I have confirmed that changing the backup time changes the time when the errors show up.

    Not sure if that helps, but I would REALLY like to understand and fix this problem.

  • I get the Shadow Copy error almost every day in the late evening hours. I run Vista Business 64-bit . . . the last version of Windows that supports Virtual Server 2005 R2. I use Windows backup in early monring hours. I can find no apparent reason, the backups suceed. Shadow copies of files are somewhat spotty. You would think every file has a shadow copy especially after being modified, However, on a few occasions, I have had to use the Restore to retrieve a recent older copy. More than half my c:\ is free space. I do have several USB 3 drives for the incremental Windows backup . . . which works surprising well despite brain dead documentation and obvious defecits in the package features.
