Error: Incorrect function. Asynchronous read operation failed Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}. Exception from server: Incorrect function. Unable to retrieve next block transmission command. Number of already processed blocks: [6170]. Failed to download disk '2bc23b75-36bc-4dc6-a7a6-0a0896103c88

When posting in the community please try to provide more information other than just an error message from the job/console.

  1. What Hypervisor are you using?
  2. What storage are you using - Production and Backup Repository?
  3. What version of Windows are you using?
  4. What version of Veeam are you using?
  5. What task are you trying to do that is throwing the error?
  6. What did the logs say - C:\ProgramData\Veeam\Backup\JobName
  7. What other information can you tell us about the issue?

Please update this post with this information for us to further help.


I have share error message

Microsoft Windows Server 2012 R2 Standard Edition, 64-bit (build 9600)


The error message does not help us!  Please answer all the questions I posted as we need to know what actions your are doing to cause the error.  Thanks for the Windows version but that does not help either we need as many details as possible not just the error.


  1. What Hypervisor are you using? NA
  2. What storage are you using - Production and Backup Repository? Qnap NAS Share Drive SMB
  3. What version of Windows are you using?
  4. What version of Veeam are you using? 12 
  5. What task are you trying to do that is throwing the error? 
  6. What did the logs say - C:\ProgramData\Veeam\Backup\JobName
  7. What other information can you tell us about the issue?

  1. What Hypervisor are you using? NA

  5. What task are you trying to do that is throwing the error? 
  6. What did the logs say - C:\ProgramData\Veeam\Backup\JobName
  7. What other information can you tell us about the issue?

So, if you are not using a Hypervisor - is this an Agent backup job?  Still no answer to questions 5 & 7 which help.  What are you specifically trying to do?  Are you backing up a physical server?  You can see how it is hard to help without all the required information.

Hi @ankitj - 

Are you using Veeam Backup Community Edition to back up a physical server, or Veeam Agent for Windows standalone on the physical server? Since you shared you’re using “v12”, I assume Community Edition of Veeam Backup (i.e. VBR)? And, you’re job is failing on the VBR server?

It looks like the Veeam Backup Endpoint service on the physical server couldn’t be started, by the looks of your error log:
08.01.2024 09:41:04.694] <20> Error  2RPC] Failed to start service 'VeeamEndpointBackupSvc'.

Can you see if this service is running on your phys server? If not, try and start it?


Also based on this line it seems you might have a VBR server managing the Agent -

[08.01.2024 09:40:46.161] <01> Info             DB] Sync agent a63275e48-791f-4484-9b18-f7e41b25c868]: managementMode tByVbr]

 

Need to validate this as well on top of other requested things asked.


Veeam Backup Endpoint service is not there..


Veeam Backup Endpoint service is not there..

So, you need to deploy the Agent to the server you need to back up.


Agent already installed 


If the Agent is deployed, then this service must exist and if not maybe the installation of the agent was corrupted, and you need to repair/reinstall it.

 


Please right-click on the agent in the VBR console and click on "rescan". Then click directly on the server in the window (then you will see the individual steps and whether it needs to install anything). What does the rescan show? Does it recognise the agent?
Send a screenshot of this


We need to take backup of physical windows. but backup got failed. have attached all information.

 

 


Again what version of Veeam VBR are you running and what agent version?  Have you tried to upgrade to the latest 12.1 release?


@Chris.Childerhose  He is running VBR V12.0.0.140 P20230718

 


@Chris.Childerhose  He is running VBR V12.0.0.140 P20230718

 

Ah yes from the screenshot.  Sorry missed that one my apologies.  I am thinking a support case at this point like I mentioned so they can do a deep dive of the logs.


I found following links for the issue online:

Backup Fails: Agent failed to process method {DataTransfer.SyncDisk}. (veeam.com)

Al Sheppard: Veeam agent error with asynchronous read operation failed

 

I would check this, alternatively I would open a ticket.


I’ve seen this issue with things like low space on the server and also issues with the VSS writers.

We have also seen it with corrupt blocks on a disk causing the issue.


@Chris.Childerhose  He is running VBR V12.0.0.140 P20230718

 

Ah yes from the screenshot.  Sorry missed that one my apologies.  I am thinking a support case at this point like I mentioned so they can do a deep dive of the logs.

Totally agree with you.
It is also the case that something is transferred according to the report (presumably Recovery/EFI/.. partition) and then it fails at C:
This would indicate a corrupt file system or a corrupt disc, or something completely different. That's what support is for (perhaps more data is also supplied to it^^)


I have run CHKDSK but 0 bad sector found

 


At this point I suggest you open a support ticket to address the issue.


 

Now i am getting different error.


Please contact Support and open a ticket.  This forum is not technical support just community help.
