2012R2 vss shadow has corrupt system hive

On 2012R2 with all updates as of Oct 9 2014, run the following commands:

vssadmin.exe create shadow /for=c:
mklink.exe /d c:\snap \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\
reg.exe load HKLM\snap c:\snap\Windows\System32\config\SYSTEM

results in :

ERROR: An I/O operation initiated by the registry failed unrecoverably. The registry could not read in, or write out, or flush, one of the files that contain the system's image of the registry.

Is this expected behavior?

I have repeated this test with 2012R2 running as a VM on 3 hypervisors (ESXi, KVM, VirtualBox).

Windows Server Backup System State error - source is FAT32

November 4, 2014, 4:05 am

Hi

Windows Server Backup cannot perform a System State backup. Error states the backup cannot be carried out unless source volume is formatted using NTFS/ReFS.

I have exactly the same problem that is described in this thread. The problem is that there is a hidden 2GB system partition called OS which does not have a drive letter assigned. This partition is formatted as FAT32 and is the reason Windows Server Backup fails. I understand I can use the solution given, using convert.exe, to convert the FAT32 partition to NTFS. However, another respondent in a separate thread, 'Erik the well read' states:

"I contacted Dell about this and was told not to touch it. The FAT32 partition contains the UEFI build and should not be reformatted/converted."

The server I have this issue with is a Dell PowerEdge R210 II. I installed Windows Server 2012 R2 using an image I downloaded from the Microsoft Licensing site.

Can anyone help me with this, please? Can the system partition named OS be converted? Should it be converted? Why is a FAT32 system partition created during installation when the built-in backup utility won't back it up?

Also, I fully expect to install 2012 in the future so would like to know if it is possible to get the installer to format the partition as NTFS and not FAT32.

Thanks.

VSS timeouts on Hyper-V guest, Exchange Replication Service, CU5

October 15, 2014, 2:48 am

I'm having a problem with a Hyper-V guest that is running Exchange 2013 CU5.  I will say I have had issues with this VM since installing CU5.

Note:  I am doing a backup from within the VM guest, not from the host.

The scheduled backup takes a long time to complete, an entire weekend to backup 150GB to an ISCSI disk.  In addition the CPU time is very high (58%) while this is happening.  Attempting to open the backup manager window consistently makes the CPU time hit 99%.  When this happens Outlook clients will fail.  When backup manager opens it will continually say "Reading data; please wait..."  If the backup manager happened to already been open, the backup job will say "Volume 1 0% of 4 volumes."

The processes taking up the CPU time are Microsoft Volume Shadow Copy Service  (24%), Microsoft Block level backup service (62%) and virtual disk service (12%).  Memory use always hovers around 65%.  If I attempt to kill the processes with task manager, there is no change.  If I use the kill executable it will say the process is not running.  I cannot stop the corresponding service either.  I cannot stop the backup.  I cannot query vss writer status.  I cannot restart the ISCSI service (device in use.)  Restarting the NAS that contains the ISCSI target does nothing.  The only recourse is to restart the server.

If I restart the server and start a backup fairly soon after, the backup completes normally, in about an hour.  During a normal backup CPU usage is at about 30%.  The Microsoft Volume Shadow Copy Service runs at 0% CPU time as well as the virtual disk service.  The Microsoft Block Level Backup Engine runs at 10% CPU time.  The scheduled backup is set to start at 9:30pm.  I have also tried changing backup times.  If I restart the server at 4 am and do not run a manual backup, the scheduled backup performs poorly.

After some digging I find these errors:

As you can see the errors happen almost immediately after the backup starts.

In addition the following VSSwriters show a last error "timed out"

Microsoft Exchange Writer
Com+ RegDB Writer
Shadow Copy Optimization Writer
Registry Writer

I will add also the following issues I have been experiencing ever since installing CU5:

1 Version buckets threshold easy reached.  Had to modify threshold and set limits on email size. Sometimes still happens.
2 After a restart of the server, the server may have no, or limited connection to the network.  It may or may not have an exclamation point on the network icon.  If there is no exclamation point, it can ping other network resources, but inbound requests and pings, will fail.  The event log shows that the network should be available while booting, but it's not since it cannot communicate with active directory.  The fix for this is to disable/enable the network adapter and then all is well.

I really need some help figuring this out.  Again, never had an issue with this server prior to Exchange 2013 CU5 being installed.

Windows Server 2012 R2 virtual DC - WSB jobs fail; causing vds.exe 100% CPU utilization

November 5, 2014, 5:41 am

I've started having issues with WSB on a Windows Server 2012 R2 virtual DC.  I had been using WSB full server backups to local disk without issue for probably 8 months or more.  Recently I noticed that the CPU utilization on the server was stuck around 100%, and it was the Virtual Disk service (vds.exe) using all the CPU.

During troubleshooting I found through VSSAdmin that I had more than one writer in the "Waiting for completion" state.  After some searching I found a suggestion to restart the Cryptographic Services service and that seemed to work.  CPU utilization and server performance went back to normal.  I hoped that'd be the end of it—it wasn't.  The issue returned the next day, and this time restarting the cryptographic service did nothing.  I tried restarting the Block Level Backup Engine service because it was stuck running and that also did nothing.  I also tried not backing-up the System State, and that didn't help.  I've had to restart the server each morning to resolve the issue, so I have stopped the backups until I find a solution.  Has anyone else experienced this behavior?

Thanks!

Windows 7 backup file management.

One of my users with a lot of data is getting a backup drive full message.
Does Windows 7 backup automatically manage deleting old backups so that new backups will fit on the drive?
I am assuming this is the way it works because it only makes sense.  I just need confirmation.

Complete PC backup failes on Vista (error 0x80070057)

Hi,

I'm trying to make a complete backup of my C: drive on another internal HDD (E:). I've tried several time and each time the backup process fails with the same error: The parameter is incorrect (0x80070057).

I've checked the article on the storage team blog but it does not address this issue (same error code is mentioned but not for complete PC backup).

I'm running 32 bits Vista SP2. Both drives are 500 GB NTFS. I formated drive E: before backup but didn't help. I checked C: and E: with chkdsk /R and did not find any errors. I also tried the "backup files" instead of "backup computer" and it worked fine. Complete backup however, seems to fail every time at the same location (the VHD file after failure is always a 105GB file).

Somebody on another thread suggested to run system file checker (sfc /scannow) but it didn't solve the problem.

I tried to create a log according to instructions in another tread but something is wrong as no log file is created: I created this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ASR\LogFileSetting with two values, LogPathName (set to D:\asr.log) and EnableLogging (set to 1).

I didn't find anything useful in the event logs or anywhere else to diagnose the problem.

I'm running out of ideas. How can I find and fix the problem?

Thanks a lot,

Windows 7 / Server 2008 R2 Bare Metal Restore 0x0000007B Stop Error

August 16, 2010, 9:03 am

Hi,

 

I am tring to restore a Server 2008 R2 Standard Ed (full installation) RTM to a virtual machine, from a full Windows Server Backup image taken of a physical machine (Dell PE 2970).  All restores fine, and looks good until it tries to boot, when a Stop Error occurs, with the following error:

*** STOP: 0x0000007B (0xFFFFF880009A9928, 0xFFFFFFFFC0000034, 0x0000000000000000, 0x0000000000000000)

I believe the non-bracketed portion means "INACCESSABLE_BOOT_DEVICE".

There is only the System Reserved volume + a C: volume (system volume) + F: volume (DVD drive) on the original server.  It has had other volumes in it before, which are correctly listed in the MountedDevices registry key, but they have not been physically present for a while.

The virtual disk I'm trying to restore to is several GBs larger than the original virtual disk on the RAID controller (2 disks in RAID 1).

I can't figure out why the server isn't booting.  I've successfully restored Server 2008 machines from physical machines to VMs before, including servers using hardware RAID cards (e.g. Dell SAS 6/iR).  The only difference I can think of is that this is Server 2008 R2, this is a 2 proc server (I've tried several virtual proc numbers on the VM to no avail), and the RAID controller is PERC 6/i, and this is the first server I've tried with that particular RAID card.

 

Any help would be greatly appreciated, even if it's to point out that I'm looking in the wrong direction.

 

Many thanks,

 

Chris

Windows Server 2008 - windows server backup fails

Hi guys,

I have problems with windows server backup. I received every day 2 notifications, 1 is Windows backup successful and the other is Windows backup failed. It's since I'm getting during every backup warning event 51: The backup storage location is running low on free space. Future backup operations that store backups on this location may fail because of not enough space.

I deleted all old shadow copies but nothing changed.  Backup is saving to 2 .vmdk files. Via vSphere client I found out that size of these files is greater than provisioned size of these disks. Is it possible ? Can be this problem ? Thanks for your replies.

How can we restore files that we don't have access too?

November 5, 2014, 10:00 am

"Backup Operators" are to supposed to have the ability to restore any file on the server.

Our backup software mounts a snapshot of a volume and we can access the files.  However when we try to copy the files to the original location, we may not have access to the directory.  We have to add permissions and go through a hassle.

So what does it take to use this "Backup Operators" group and enable files to be restored?

How Can I Schedule A Backup LESS Than Daily?

I'm currently using Windows Server Backup (in Server 2008 R2) to an attached HDD in an eSATA dock, which INCLUDES the Bare Metal Recovery AND System State.  There is, and will be for the near future, very littl activity on my server and no significant daily changes.  I'd like to be able to, for the time being, schedule the backup to occur only weekly, but Windows Server Backup doesn't seem to provide that option.  Currently the backup is scheduled to occur daily, but I've only been mounting the disk weekly.  This causes six days of "Backup Failed" error messages, and I'm afraid that I may not be getting everything that I need when the weekly backups occur.

I also have two Win 7 computers  backing up the same way, but Win 7 provides for a WEEKLY option.  Is there any way to properly schedule weekly backups on my server???

Essentials Experience - Backup Unchanged Files

I have Windows Server 2012 R2 Standard installed with the Essentials Experience role installed.  The server drives are backed up on an external USB3 drive enclosure containing 4 drives twice a day.

As the server backup is taking a long time, I diagnosed that it was backing up many files who haven't change since a long time.  Some of them more than a year ago, as per the modified date of the file.  I can't say if it is backing up all the files each time, but I know he copy many unchanged files.  I was expecting that it would copy only the changed files.

Is there something wrong with my configuration?

I have spent the day googling but can't find an answer.

I want to apply GPO "set time limit for disconnected sessions" to windows 2000, 2003, 2008 and NT.

I thought of applying this to my clients thru DC 2008r2.

Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Session Time Limits

But I can see this policy supported on " At least Windows XP Professional or Windows Server 2003 family"

I need your help  in  setting up this policy to older version of windows, Especially windows 2000, NT.

Our environment has windows 2012, 2008, 2003 , 2000 and NT

Also advise me of any other stuff (separately) that I can use to make sure that users are logged off from disconnected RDP sessions.

please reply at earliest..

Unable to stop Windows Server Backup

October 30, 2014, 11:01 am

We've been running Windows Server Backup on Windows Server 2012 Essentials successfully for a while now.  Backups are performed nightly and have been completing successfully on a schedule.  We have been rotating between 3 (sometimes 4) USB connected external drives.  Yesterday, I changed the configuration to target just 1 drive.  It was 75% complete this morning but I wanted to stop the backup to continue some configuration changes (we recently encrypted both our internal system and data drives -both are included in the backups - and I wanted to start a BitLocker encryption of one of another backup drive)

The documented way to Stop a Backup from Dashboard is to simply find your server in Devices, right-mouse-click it, and choose "Stop backup for the server".  Unfortunately, this has no effect and the backup appears to be hung (have waited a couple of hours now for it to stop gracefully).

I have tried launching wbadmin but it, too, appears to be hung showing "Reading data; please wait..."

Short of physically disconnecting the USB drive or rebooting the server, is there any way to stop the processes involved?  I have had trouble trying to locate the processes involved via Task Manager.  When I do, I can usually kill backup in this fashion, but I usually have to follow this with a server reboot before I can use Windows Backup successfully again.  So any help here would be appreciated.

This issue of not being able to stop a running backup has been frequent with us under many different circumstances and usually happens whenever we suspect a backup will not finish in a timely fashion (for example, changing the backup schedule to target a different number of drives when not all our drives are physically connected seems to confuse Windows Server Backup).  Workaround has been just to wait for the backup to finish - even if it appears to be hung.  Sometimes it finishes, other times not.

Checking the event log, it shows a volsnap Event ID 25 error from early this morning that may or may not be related to the fact we can't stop the backup.  Interestingly, the description in Event Viewer for this error reads "The description for Event ID 25 from source volsnap cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event:  \Device\HarddiskVolumeShadowCopy239 I: The locale specific resource for the desired message is not present"  -- Why??  

I think this is referring to our recently encrypted drive which I assigned a device letter of "I:".  It is connected to the server along with our "hung" backup drive that I had targeted yesterday when I changed our Backup Schedule and configuration.

Thanks in advance for any help or insight you can share.

Carl
