    I am using Server Essentials on a 2012R2 server.  This is a single server network.  Backup services were up and running for a couple of years, but suddenly they aren't functioning.  I can launch the backup using a script and task scheduler, but using server essentials I can't get it to finish using the setup action.  When I launch the setup wizard from the link in the server essentials dashboard the following is returned.

    "Cannot setup server backup"

    "Make sure that all backup services are running, and then try again.  If the problem exists, review the system alerts for related information."

    Using services.msc I can see the backup service running.  VSS service was set to manual so I started it manually and reran the wizard and received the same error message.  

    Are there other services  I should check?  

    I looked in the event viewer but don't see any errors related to backup services.  I do see that server essentials had unexpectedly terminated.  When I came into today to work on this I noticed that server essential service was not running, so I started it.  

    What else can I check or do?

    I shutdown and restarted the server.  On the restart the windows server essential management service terminated unexpectedly.  But from the event viewer (is there a better place to look for specifics on the error?) I can't tell why.  Is that keeping the backup server setup wizard from starting?

    We have two new Windows Servers 2012 R2 that I'm trying to set backups on using a script. When I used the -allCritical switch, I get the error specified in the subject. When I look at the partition information using diskpart, I see a 2048 MB partition with no drive letter labeled as System that is FAT32. I was never prompted to my recollection of what file system to format the partition with. Is it safe to assign this partition a letter, convert to NTFS, and then remove the drive letter?

    I am in need of KB2781272 for my Windows Home Server 2011 but all links to its existance are no longer valid. I understand that support for this product stopped in April of 2016 but I am only looking for a hotfix file that, I would assume, still exists someplace. I am not looking for support, just the hotfix. Does anyone know where I can find it? Microsoft support has taken the attitude that its a dead product and will not seem to help. Not sure why there is no archive of old hotfixes someplace. Anyone have any ideas where I might be able to get this hotfix?

    This error message isn't that uncommon but what makes this issue unique is that Edge will say its a DNS issue, however google chrome, IE, firefox all works. Also if I switch to WIFI or MobileLTE Edge will work. And here is another kicker, it only happens in the morning after it has been either on a business trip and at home and when i get into the office this error message will last about 10-15 minutes before it starts working again.

    I've tried ipconfig /flushdns

    i've tried going to edge and about:flags; CTL+Shift+D; disable "Enable TCP Fast Open"

    Any ideas?

    I have a Windows Server 2016 Core hyper-V cluster with 3 Nodes, and a Windows Server 2016 GUI Mgmt Server.

    I can mange all roles of each nodes with the mgmt Server without any problem except the Windows Server Backup. If I want to run from the MGMT Server the "Backup schedule" or "Backup now" assistant on a cluster node I get the error "The parameter is incorrect". 

    I do it like this:

    1. MMC on MGMT Server

    2. Add/Remove Snapin

    3. Select Windows Server Backup

    4. Choose the option "An other computer" and put the name of a cluster node. 

    5. Right click on "Local Backup" and "Backup schedule"

    The crazy thing is if I stop the "Cluster service" on the target node, the "Backup schedule" assistant runs without any error. 

    Has anybody any idea?

    I am wondering if you can assist?

    I currently have the issue that Windows Backup won't finish successfully.

    Here is the error message - see: http://prntscr.com/lix19f

    I have tried the solutions here: https://answers.microsoft.com/en-us/windows/forum/all/windows-7-backup-fails-with-0x81000015/e2b0d799-d99f-4394-9a6a-8ff5d8cd0d39

    However still no luck.

    I have also removed Winzip and Peazip from my machine, as per: https://blogs.technet.microsoft.com/win7/2011/03/07/error-0x81000015-appears-when-you-back-up-files-in-windows-7/

    Can you advise what the next step is so I can resolve the issue?

    Below are some screenshots from Belarc Advisor to show my current computer set up







    Any advise would be appreciated

    Kind regards,

    I've captured from a Windows server 2016 my partition C:\ & D:\ on F:\ with this command line : "wbadmin start backup -backuptarget:F: -Include:C:,D: -allCritical -vssfull -quiet"

    And after I've copied the folder WindowsImageBackup from F:\ to an external hard drive G:\

    I try to restore my server from the Hard drive and I have this message : 

    Do you know the best practice to skip this error message ?

    we're having an issue at a customer where the C: drive will fill up over the course of a day or 5 (fluctuates).

    It's a 2012 R2 server with 4 VM's (Hyper-V) on it. 2 of the VM's are linux (ubuntu 18.04 to be precise). The back-ups have worked w/o issues for about a year, but recently C: has filled up to the point where it breaks 4 times now. Every time there's a bunch of {guid}{guid} files in System Volume Information. Last time it filled up entirely there were 650GB worth of them...

    Can't find much on why they aren't removed automatically, would presume they should be removed automatically at least.

    Can get around them by deleting them with diskshadow (vssadmin doesn't allow to remove them), but looking for something that makes more sense than scripting/scheduling that. Backup shouldn't fill up the drive to the point where things break.

    Backups themselves go to external HDD (USB) btw. The D: drive doesn't fill up. D: is a SSD, some vhd(x) files of the VM's are on D: for performance. In fact I've never seen the size of System Volume Information on that drive pass 1MB.

    Any ideas what might be causing this? Presume it's related to some windowsupdate installed 1,5-2 months ago.

    We only back-up the Hyper-V part by the way. Shadow copies aren't enabled and from what I understand servers don't support system restore points.

  • 11/20/18--01:12: FilterManager Event ID 3
  • Filter Manager failed to attach to volume \Device\HarddiskVolume58. This volume will be unavailable for filtering until a reboot.  The final status was 0xc03a001c.
    The error appears every time you back up. OS is the Windows Server 2016 standard. Can you tell me why these errors arise and how do I remove them? I note that this is a completely clean system.

    Hi there,

    We have a problem with 1 of our domains, we want to install our backup tool from Acronis with Exchange application. Herefore we need to login as domain admin. This shows us the following error:

    Cannot collect the metadata of Microsoft Exchange Server

    The specified user does not have enough rights to create an application-aware backup.
    TROUBLESHOOTPlease specify the credentials of a user who is a member of the 'Organization Management' role group or disable the application-aware backup of Microsoft Exchange Server.

    We contacted Acronis, they told us; the problem is using the command: WHOAMI /GROUPS does not show any domain groups.. This is why Acronis software thinks our domain admin is not member of the organization management.

    Somehow this does not work on any of the servers in this domain. We have more domains where this command DOES show domain groups.. We can't find anything different in the domain.

    Running Windows Backup on a Windows Server 2012 to a Network share

    I think the backup is completing & is listed in ALL Backups but I see the message

    "Event Log is inaccessible. Only messages for currently running operations will be displayed."

    Any ideas how to fix the issue?

  • 11/24/18--21:48: Different Volume GUID's
  • Hi

    I am running a script to map a cluster shared volume to a server and take backup of that volume. But each time volume is mapped i am getting a different volume GUID for access path addition. This is creating a problem in mounting the data to a folder form which i am planning to do a Netvault file system backup. I would like to hear out some sggestion for this.

    Thanks in advance

    I've got an issue and don't know how to solve

    1- I had a Hyper V installed on windows server 2012 r2
    2- I've installed and configured file server and configured windows server
    3- I've configured backups by windows server backup to take backup from the needed files on a VHD disk
    4- Hyper V server went down and I couldn't find all the files and folders on the virtual disks after attaching the old virtual disks
    5- I was able to attach the backup VHD partition to restore the backup as pint no# 3
    6- after mounting the VHD the partition say it's unallocated and need to be formatted

    So please could someone help me with this issue :(

    After the Windows 10 version 1803 upgrade on April 30, 2018, my System Image Backup keeps failing withe two messages. "The backup failed" "The RPC server is unavailable (0x800706BA)".

    Note that the System Image Backup worked before the upgrade. The upgrade completed OK and I have not found any other issues.

    I checked that =1= The RPC (Remote Procedure Call) service in Services is active and running and =2= the DCOM (Distributed COM) is enabled. There used to be a SYSTEM disk when I did the defrag, the defrag does not show the SYSTEM disk in version 1803.

    Is it a bug, or is there a fix or should I try the Image Recovery (that might fail as well).

    I have a Windows 2008 R2 server named Server that runs a backup each night to an encrypted USB drive attached to the server. I shared the drive on the server as shown below and configured Windows Server Backup to backup to the local shared folder.

    • \\Server\Backup

    Everything worked well for several months with the backup speeds being about 1 GB/min (15 to 20 MB/s). At the beginning of this week, I noticed that the backup speeds reduced to 1 to 2 MB/s which resulted in the backup not completing before the encrypted disk was automatically dismounted.

    After much research and testing, I believe that I have narrowed down the cause of the issue to an issue writing data to the local UNC path of \\Server\Backup as shown by comparing the following tests.

    Test 1

    • c:> copy largefile h:\

    The above DOS command copies the file to the encrypted drive mounted at h:\ quickly.

    Test 2

    • c:> copy largefile \\Server\Backup

    The above DOS command copies the data to the same location but was 33x slower that the Test 1 DOS command.

    I duplicated the above results using the xcopy command instead of the copy command but could not duplicate the above results on my Windows 7 computer. On my Windows 7 computer, the two versions of the copy performed the same.

    The following are some additional observations:

    • If I change the backup location to an external UNC like \\Sever2\Backup, everything works well.
    • After repeatedly running Windows Server Backup after make changes such as restarting the server and tweaking the NIC parameters, the backup will all of a sudden start backing up at the normal speed but this will only last for about an hour before it reduces back to the slow backup speed.

    I have a test server which is exhibiting some strange behavior with Windows Server Backup.  Perhaps I am just performing the backup incorrectly and need to use another method.  It is a Hyper-V server running Windows Server 2012 R2 with guest VM's running a domain controller (2012 R2), Exchange 2013, SQL Server 2017, and SharePoint 2019.  I created a backup job on the Hyper-V server that backs up the necessary system volumes/partitions, and also includes the VM's within Hyper-V.  When checking the progress after the backup is complete the data transferred shows "xx.xx of xx.xx" as expected for everything except for the SharePoint VM.  That one shows 374.00MB of 32.99GB.  The total data transferred shows 99.10GB.  When I add up all of the VM's -except- for SharePoint it adds up to 98.73GB, including SharePoint adds up to 99.10GB.  While it was backing up SharePoint it counted up past 374MB, but from what the results show at the end it appears the SharePoint VM has not been backed up properly.

    Should the backup be performed in some other way?  Perhaps running Windows Server Backup directly from the guest OS instead of from the host Hyper-V OS?

    On a related note, I am curious if there would be any issue with inconsistencies of the state of the data performing the backup in this manner?  The SQL Server is also running as a VM.  Is it critical for the backup of the SQL Server and SharePoint server be done at the same time so there is no mis-match of configuration or other data between the VM's?

    Hi all,

    I have a server running server 2012 r2 with the essentials role installed. There are several clients attached to the domain which are configure to regularly backup to the essentials server (on a 5TB ReFS volume) and the server also hosts redirected folders for the clients along with a fairly large (for a home anyway) collection of music and photos etc all stored on ReFS formatted volumes.

    I have purchased a couple of 5TB external drives which I intend to use as additional backup drives which I will rotate so that there is always one in a location away from the house.

    The issue I have is with configuring backups onto the external drives. As I see it I have two issues - ReFS drives do not allow incremental backups and I cannot configure a subset of client backups to be backed up onto the external drives. This means that the external drives will run out of space after a very small set of backups which limits their usefulness.

    Any suggestions on how to best configure this sort of backup?

    I have the second server now that cannot restore from backup; not even a single file.  Microsoft broke the ServerBackup system.  I wonder why!
