When in doubt empty the magazine...
We have a Windows Server 2012 R2 fully patched.
Running the Native Windows Backup hangs the Server and we have to cancel it. In backup logs show (below).
We stop/started the relevant VSS services and ran a SFC we comes up ok. I'm at a loss what could cause this.

I have three Microsoft Windows Server 2012 R2 Standard servers running on Dell PowerEdge machines that serve as Hyper-v hosts for my various virtual machines. Each server has a scheduled backup similar to the following:
Notes:
The issue is that the backups will run for several days successfully and then will stop running. After the backups begin to fail, I see the following when I open Windows Server Backup tool.
I also see Event 19 in the event log when the scheduled backup runs:
If I attempt to run the backup using the wbadmin command line, I see the following error:
If I sign out and then sign on, the issue is immediately resolved and I can see the backup history in the Windows Server Backup tool. The backup will run again for several days until the issue occurs again.
The cycle of the issue on the three machines is very similar. In other words, the backup will run successfully on all three machines for 2 days and then fail on all three machines and continue to fail until I sign in, sign out and then sign in.
Note: After verifying that the server backup is running with a sign in, sign out & sign in. I typically sign out again.
Any ideas?
I have server 2008R2 Standard OS.
Windows Server backup is not working, VSS Writers also not listed and Tried to re register but nothing work for me. When open windows server backup it also gave error " A Fatal error occurred during a windows server backup snap in(wbadmin.msc) operation error detail unknown error 0x80042302

I have also tried to remove Windows Server Backup feature and installed again.
Can anyone help on this?
Thanks

Can i use Resilient Change Tracking with Windows Server Backup? - If yes, how?
I did a backup on Hyper-v Server 2016 with performance set to incremental to an internal volume. I expected to see files like *.mrt and *.rct in the directory of the virtual hard disks, but there isn't.
Any links to that topic are welcome.
Thanks, S.
I have tried to run a bare metal backup on 2 servers now. 2016 Server with Hyper-V with 1 VM(MS SQL) and an RD server with 2016 server. Both have failed.
So... I find it funny that there is a dedicated forum to Windows Server backup and what the hell am I doing wrong. Both servers throw and error something along the lines of: "
Backup of volume C: has failed. The requested operation could not be completed due to a virtual disk system limitation. Virtual hard disk files must be uncompressed and unencrypted and must not be sparse.
Is this telling me I need to move all VMs and RD's to a secondary volume?
Hello,
I am experiencing sporadic Windows backup failures on my server. I am backing up to an 8TB USB drive and have tried multiple drives from different vendors. Some nights the backups complete successfully. Some nights I get the following errors:
There was a failure in preparing the backup image of one of the volumes in the backup set.
Detailed Error: The process cannot access the file because it is being used by another process.
Other nights I get a warning with this message:
There was a failure while compacting the virtual hard disk on the backup location.
I have Antivirus completely disabled and have ensured that no other backup sets are running at the time of the backups. I have also disabled other non-Microsoft services. I have turned of all power-saving settings on the server. I can't seem to track down what
could be causing file locks. Any help is much appreciated.
Hi Guys,
We have a Multi DC domain setup with 2 servers in the main office, which are used as main DCs. Each of the branches has a DC on site (all are in the same domain).
We want to set up a disaster recovery plan wherein we want to restore the AD to a particular date. How should we go about restoring the machines?
Cheers

Dear All,
I have a problem with Shadow Copy on Windows Server 2016 Standard (Licensed). I am running as File Server Failover Cluster. My storage is Synology DS1517+ (HA Storage). I have created a volume and a storage pool (12TB). I have create 4 ISCSI targets and 4 LUNs to provide ISCSI client to connect. I have connected and succeed via ISCSI client and the drives are usable.
Next, I want to configure Shadow Copy for all drive that linked from ISCSI initiator client to the storage (Synology). I can configure shadow copy volume on ONLY one drive (Y: drive) and show on previous version of windows explorer and another drives (X, Q and Z) are can create on drive property but it's not show on the previous version of Windows explorer on that drive.
What is the main issue? Is it issue from Single Volume/Storage pool or another issue?
Note: if I can configure shadow copy on many drives on VMWare
Thank you,
Sor
Hi everyone,
I got a problem when I use Avamar on some servers, only Windows Server Enterprise. The backup is not working, and when I'm looking into logs, I can see that I got an error about "System Writer". Indeed, when I launch "vssadmin list writers", I should see "System writer" but I don't.
I searched on internet to get some solutions, like giving some rights on some folders, but it changed nothing and then I saw that I could install the Fix484021 to fix it. But... the fix isn't working on my OS :( (link : https://support.microsoft.com/en-us/help/2911752/system-writer-is-missing-and-backups-fail-in-windows-server-2008)
I tried to contact the support by chat, but I don't get an answer from it because it's laggy.
Waiting for help.
Thanks in advance.

Clément.
Hi,
one of our W2K12 R2 Std Server always stops with BSOD 0xEF or 0x7A when Windows Server Backup ist starting.
After many hours of research and trying, i found out, that there must be a problem with the registered writers for VSS. The 'DISKSHADOW' command 'LIST WRITERS' leads to same BSOD's.
My questions about that:
1. I did not find the registry key's where the vss writers are registered to check them manually. Does any1 know where the writers are registered?
2. Does any1 know how to repair the registry for the vss writers? I found this article 'http://kb.macrium.com/KnowledgebaseArticle50010.aspx' from 2014 but im not sure if this is still a good advice for W2K12 R2 server?
Any help appreciated. Thanks in advance!

I'm testing 2008R2 SP1 Windows Image Backups. Two Servers alpha and omega each have an older backup stored on the other server, in shared folders. In Windows Server Backup - Recovery Wizard - Specify Remote Folder I get to specify the UNC path "to the remote shared folder that contains the backup." Easy, right? I have tried (from \\alpha)
\\omega\WindowsImagebackup (which is the shared folder)
\\omega\WindowsImagebackup\alpha
\\omega\WindowsImagebackup\alpha\Backup 2011-03-22 133034
These all error with
"The specified remote shared folder does not contain any backup. Provide the path to a remote shared folder that contains backups."
Must be corrupted? But, vice-versa, trying from \\omega and looking at \\alpha i get the same error.
Tell me I'm missing something stupid.. Thanks!
Hello,
I need to backup 20TB of data. The client is too cheap to do anything but TWO 12TB external drives. THey want to use Windows Server native backup.
How do I back up some VMs to one drive and some VMs to another.
Please don't explain how important backups are and how they should consider another alternative. I have to implement what they want. I'm familiar with VEAM, disk arrays, replication servers, cloud backup, etc. There is ZERO money in the budget for anything else. They already have the two external drives.
I am using windows server backup with 2012 r2. I am able to pull up bare metal for previous evening but not earlier dates. I am on a new virtual guest and need to restore from its previous version which is no longer available.
How to I get the previous dates to show for Bare Metal... They are available in the GUI.
Thanks.
Hi guys,
I recently installed 2 Windows 2016 servers on a Hyper-V 2012 cluster. I'm backing up to a brand new QNAP NAS with *plenty* of storage space (just checked, 11TB available). Verified the access credentials, all good. The 2012 server guests are backing up fine, but the 2016 servers initially failed with the event id 513 CAPI2 error:
Cryptographic Services failed while processing the OnIdentity() call in the System Writer Object.
Details:
AddLegacyDriverFiles: Unable to back up image of binary Microsoft Link-Layer Discovery Protocol.
System Error:
Access is denied.
I followed the steps mentioned in https://answers.microsoft.com/en-us/windows/forum/windows8_1-hardware/cryptographic-services-failed-while-processing-the/c4274af3-79fb-4412-8ca5-cee721bda112?auth=1 , but to no avail (rebooted the server too).
The backups keep failing with event id 517:
The backup operation that started at '2017-09-19T01:51:23.118823700Z' has failed with following error code '0x807800C5' (There was a failure in preparing the backup image of one of the volumes in the backup set.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
I tried changing the backup selection as well, no success...
I have read about hotfixes for earlier releases of Windows Server. Would there be one for 2016 as well?
Any help will be greatly appreciated!
Thanks!
=== Quick update: I just configured and ran the backup on our 2016 domain controller, which is on physical hardware. Same result.
Followed by event ID 513 CAPI2, event id 517 error code 0x807800C5 and event id 1001

Hello,
Whe have successfully restore a windowshyperv guest server to a preious date using WIndows Server Backup Bare metal restore. We actually created a copy of the current guest machine and create a new guest machine virtual machine and attached the copy of the virtual hard drives and also the backup drive. The only difference is we did no connect the networking of the virtual machine to the virtual switch. We then did a bare metal restore to the copied virtual machine which was successful.
The quesion I have is the network adapter on the restored virtual machine is there but it shows "disconnected" and it also no longer has the static IP address. How do I get the network adapter to duplicate what had been previosuly configured? Do I have to restore with the network swithch attacdhed(I do not want to do this)? Or can I reattach the network switch afterwards and the static IP will come back and the network adapter will no longer show "disconnected"?
