Unable to release guest. Unfreeze error. (backup job failed. Cannot create a shadow copy of the volumes containing writers data. A VSS critical writer has failed. Writer name: NTDS (class id xxxxxxxxxxx) Writer state (VSS_WS_failed_at_post_snapshot. Error code (0X800423F4). Error: unfreeze error (backup job failed.

Tried the following:

I rebooted the server.

Ran vssadmin list writers - VSS NTDS was stable and was not in an error state.

Ran job but it failed with the same error.

Ran vssadmin list writers - the VSS NTDS was in error.

Ran diskpart  - automount - the aotomatic mounting of the drives is enabled.

Deleted .bak files in the registry in the following reg area:  HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList

Rebooted the server.

Ran vssadmin list writers - NTDS VSS was stable and was not in an error state.

Re-ran job and it failed with the same error

Any assistance would be great.

Ive got a HP Prolliant ML350 Server running the free HP Build of VMware - HPE-ESXi-6.7.0-iso-Gen9plus-670.10.3.5.6 (Hewlett Packard Enterprise). The server has 2 CPUs with 8 cores per socket and 80gb of Ram. I have 3 guest running Windows 2012 server and Im trying to setup Veeam to backup the boxes but Im getting the following error in Veeam which indicates something is not right with the licensing.

Processing Main SQL Server Error: Current vSphere license or ESXi version prohibits execution of the requested operation.

Sounds like the HP VMware license is the issue and I probably need at the very least an VMWare Essenttial License key - does this key have to be bought from HP or can I get it off VMWare themselves? Can I apply the license via the web gui of the VMHost?

Windows 2012 R2

I use the Veeam Agent to backup this physical server

The Veeam Agent requires the Shadow copies to be cleared in order to get a successful backup.

I wrote a small PowerShell script to accomplish this

$LogFolder = "c:\util\logs"
$LogFile = "vss.txt"

remove-item -path $LogFolder\$LogFile -Force 

vssadmin list shadows >>$LogFolder\$LogFile
vssadmin delete shadows /all /quiet >>$LogFolder\$LogFile
vssadmin list shadows >>$LogFolder\$LogFile

Select all Open in new window

 
The results below.

For some reason it does not delete all the shadow copies.

This has been working for a long time and this started about a week ago.

When I run the commands manually I get the same results

I had a VM server stop responding during work hours. I was unable to reset the VM due to an incomplete snapshot removal initiated by Veeam. Ultimately, we stopped that removal, rebooted the server (it wouldn't power on still even after the stopping, so I had to reboot), and got the VM up and running.

Now, I have two Veeam temporary snapshots that are showing up. It seems that one of the drives has 2 delta disks, but the other three drives have just the one. The 2 disks is likely due to the interrupted snapshot.

Veeam suggested Consolidation, which I agree with, especially since it's a database server and changes have been made, so I wouldn't want data loss. My vSphere client though is showing a "No" in the "Needs consolidation" column. I have never done a consolidation, so I'm not sure what to expect. Is this my best (only) option? Will it even run if "needs consolidation" says no? Any concerns I should have (I'll obviously do a backup beforehand.)

Thanks.

Hello Experts - I am currently running ESX 6.0 across a WAN doing replication/DR with Veeam.  I am about to add a new site that will be running ESX 6.7.  Are there any compatibility issues between 6.0 and 6.7 that will cause problems with backing up and replicating VMs using Veeam between versions?

Now using Veeam to backup Vmware guests, can Veeam restore particular files only in guest?

Dear Experts, Can you suggest on this issue? We tried to convert a physical to virtual server using Veeam but got this when booting. I tried both BIOS and EFI option but it did not help?



OS: Window 2012R2, ESXi 6.5

I wanted to give a "least privilege rights" to a backup user on my Vmware center.
That username will be entered in my newly installed Veeam server.
So I created a user name _bkpsrv and give it AD group "Backup Operator"
Then I went on my esx, right click on it , select ADD PERMISSION
I selected "Backup Operators" and selected "VMware Consolidated Backup user" and pressed OK.


Veeam still don't accept to connect using it AND WORSE, now when I right click on my esxi, most options are grayout!

may I know if the replication job for SQL server in process will impact on user access or not .

I am replicate about 5TB data over to remote site this will take about a week to finish .

VMWare host running ESXI 6.0 U3 on a DELL R740.

One of the basic Win2012 R2 server is not able to be backed up. When launching a backup task from Veeam, it fails with "operation not allowed in current state".  Looking at the VMWare host, this error appears to be passed through from an attempted Snapshot request.  See screens below.


 

I've two hypervisors with 20 + VM and I'm planing to purchase "Veeam Backup Essentials Enterprise 2 socket bundle".

How many licenses would be required ? 1 or 2 ?

I will be using only one backup server.

Chanaka
