Windows Server 2008 R2 System State backup

Running a member server 2008R2 server. Backups have been running fine for some time but recently ceased to run. We have been using CloudBerry Lab Enterprise Backup to store backups in cloud storage.

I started looking at CloudBerry logs and did not get much information.

So I started looking into the Event Viewer application logs and noticed some errors from the Volume Shadow Copy Service. I found four VSS Errors with EventID 8194 corresponding to backup failures.

I saw that some of them were hung in State: [ 5 ] Waiting on completion and found a batch file that re-registered the VSS components and restarted some services, which took care of everything but the 'IIS Config Writer' but that cleared after running another manually.

I did a little digging and found some information about a registry key controlling callback access into VSS. I added REG_DWORD values underneath HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\VssAccessControl for several accounts.

I attempted to add domain accounts but received the following.

I followed the instructions and tried several times using the FQDN, NetBIOS domain name, NetBIOS domain name in capitals, UPN. Never could get the domain lookup to work, but I suspect that's due to the NetGetLocalGroup() call. Local group accounts do work ( I added the local Administrators for good measure ) but the articles that I found all specified creating a domain account.

The next step in the article was to check permissions on the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\Diag Key. I noticed that there were no permissions for the Nt Authority\LocalService and Nt Authority\NetworkService "identities." I immediately ran into the problem of not being able to add those using the GUI. I wasn't sure if it could be done using a command line utility, WMI, or if I had to do it using C++. Oddly enough, once I added permissions to the local Administrators group and started the Volume Shadow Copy service again, the permissions magically showed up. ~Great~

That seems to have resolved the warnings and errors on the startup of the Volume Shadow Copy service so I moved on to the next step. (NOTE: Exactly a week later we were right back to 0x80000005 Access Denied errors)

I thought I would cut down on some of the overhead by running a system state from the command line with wbadmin start systemstatebackup -backupTarget:\computername\temporraryshare.
Technet Wbadmin.exe Running the backup to an external hard drive connected to another server continually failed. Checking the Event Viewer underneath Microsoft\Windows\Backup\Operational yields:

Looking up information on Event ID 5 here: Windows Server Backup Events and looking up HRESULT information specific to same here: Windows Server Backup HRESULTs

Checked Local Group Policy to make sure nothing was set. Started looking at event details.

Both logfiles were completely empty 1K files.

Referencing MSDN HRESULT structure information: MSDN HRESULT MSDN HRESULT values NTSTATUS values Win32 Error Codes

Checking Detailed HRESULT properties and using the Windows Calculator to translate into HEX from DEC yields

HRESULT = 2155347997
hex = 8078001D

HRESULT = -2139619299
HEX = FFFFFFFF8078001D


HRESULT = -2139619228
HEX = FFFFFFFF80780064

which I couldn't locate in the referenced information. I thought it was weird that a built in didn't have regular facility code but instead looked like it was all flagged on, etc., but okay.

What's strange is that there's plenty of disk space ( 1.5 TB free ) and write permissions are okay because backup files are created in the folder ( .xml, etc. ) including the VHD, all files are enumerated and indexed prior to the error taking place. I can also successfully backup system state from that sever that the external drive is connected to locally, and I can run system state backup from the server I'm working on over the network to a UNC share on my desktop, but not one to the other. With the exception of a single file error logged in %SystemRoot%\Logs\WindowsServerBackup when backing up to the desktop share.

 Error in backup of C:\Program Files (x86)\Common Files\Adobe\ARM\1.0\ during write: Error [0x80070003] The system cannot find the path specified.

I traced WBADMIN.EXE and WBENGINE.EXE using process monitor and the exact moment that the backup fails there is a WriteFile call that returns an INVALID PARAMETER result.

Additionally strange is that the backup had been running to the 2nd volume on the drive and then suddenly it was flagged as having a portion of the system state ( IsCritical=1 ) present and was no longer a valid path to write. I can't disable Volume Shadow Copy on that volume as it's needed for CloudBerry Lab and that seems to be what's preventing the System State Backup from running to the local disk ( I know there is a registry key that can be set to force this KB Article Number(s): 944530, but it seems like there are way too many problems with doing that in this scenario ).

That being said, this is what I see from the disk properties:

But using vssadmin list shadows shows:

Running the backup using wbadmin to the other server still gives this:

Summary of the backup operation:
------------------

The backup of the system state failed [7/2/2015 3:58 PM].
Log of files successfully backed up:
C:\Windows\Logs\WindowsServerBackup\Backup-02-07-2015_15-54-35.log

Log of files for which backup failed:
C:\Windows\Logs\WindowsServerBackup\Backup_Error-02-07-2015_15-54-35.log

The operation ended before completion.
The parameter is incorrect.

But I can do the same thing to the share on my desktop successfully. It also seems that fixing these issues only lasts for a few days before the same errors crop back up. I found a specific hotfix for the 'parameter is incorrect' issue, but on installation I received a message that it was not applicable to my system. ( I believe it is 417386_intl_x64_zip ) KB Article Number(s): 2182466

I still get this when attempting to start a new backup to the same location previously attempted, making me think that the problem is somehow related to the CreateFile call.

  VhdDeleteReason Backup VHD is corrupt 

So I'm running out of ideas for methods of attack. I can't seem to find very specific information on the HRESULTs. Sometimes I end up with an EventID of 5 and an EventID of 517. Occasionally I've seen other values for the HRESULT as well, such as the infamous 'Error enumeration files'. Below are the Process Monitor ( from SysInternals ) tabs for the WriteFile event.

Anyone have any thoughts on this? Help is greatly appreciated.

Seen such errors with various backup apps, usually it's a COM permission issue.

1. Start > Run > dcomcnfg
2. On the right-side of the newly-opened windows, expand the Component Services > Computers > My Computer nodes.
3. Right-click on My Computer and select Properties from the contextual menu.
4. In the newly-opened window, select the COM Security tab. look up for the Access Permissions options panel and click to the Edit Default button.
5. In the newly-opened window, add the SYSTEM and Network Service users (if not already there) and grant them the Local Access permission by activating the proper checkbox.
6. close everything and restart the machine.
