Hello,

please give support some time to work on your case, as you opened the case with evaluation support on Friday (evaluation tickets are not processed during weekend).

Best regards,
Hannes

[MERGED] Backup Up VEEAM VM fails with Error 14009 - Failed to upload disk

Post by L0g333 »

Hi there :)

for some days i have a problem with backing up our VEEAM VM, that used to work like a charm for more then a year now. After ~19.5GB of transferred Data, the Backup of the VEEAM VM fails with the following error (All other VMs are backed up without any problem):

Code: Select all

06.02.2019 12:26:13 :: Error: VDDK async operation error: 14009. Value: 0x00000000000036b9
Failed to upload disk.
Agent failed to process method {DataTransfer.SyncDisk}.
Exception from server: VDDK async operation error: 14009. Value: 0x00000000000036b9
Unable to retrieve next block transmission command. Number of already processed blocks: [62740].
Failed to download disk.
Some background information to the infrastructure:

VEEAM Backup Server (Windows Server 2016, VBR 9.5.4.2615) and Backup Target (QNAP NAS) are running in LAN A.
ESXi 6.7 Host (Build 11675023) and vCSA 6.7 (Build 11726888) are running in LAN B.

-> VMware and VEEAM are up-to-date.

LANs are seperated by Sophos Firewall. Any-Any FW Rule doesn't change the result.

VEEAM Backup Server is running as VM on the ESXi Host, and fails backup up its own VM. There's no seperate Backup Proxy in LAN B. VEEAM is connected to vCenter.

After hours of googling and reading, rebooting and updating, i am running out of ideas. Maybe someone here has an idea, what the cause of this could be.


I found this on that topic: https://vinfrastructure.it/2018/10/veea ... ror-14009/ But I am not sure if that can be the answer. We didn't touch the network and don't encounter other network problems.

Thanks a lot guys!

Thank you for that hint @v.Eremin. I thought, I'd open a forum post instead of opening a ticket, since the problem isn't that severe. I'll catch up on this later, when i'm back in the office.

I actually wasn't clear about the fact i'd need a support ticket for technical issues. I must have overseen that little notice, when creating my forum post. Maybe it would be helpful to make the forum rules (veeam-backup-replication-f2/rules-of-po ... -t755.html) a sticky post.

Sorry for the inconvenience.

Just to give some additional background. This forum is not a support forum and only some of the support members are part of the community because of personal interest. Main part of the forum is to interact with Veeam product management, R&D and systems engineers/architects.

We are having exactly same issue.
support case 03404281

on the target vm :
we did Filesystem checks -- come back clean
Disk checks in the OS --come back clean
Disk checks at the VMFS level-- come back clean
All snapshots have been removed to eliminate any potential issue with that
Nothing configuration wise has changed on that machine
Then :
re-run backup still failed with same error .
re-create a new job for the target vm , returns same error

Thanks everyone for including their support case IDs. The issue is not wide spread, so the more material we have we work on - the better!

Hi
we are getting the same error for one of the machine. Do the Veeam has a solution for this error?

I am getting the same issue.

Support Case# 03665196

Started happening about a week after upgrading VMware to 6.7. Just the one backup failing, it is an application aware backup of a SQL server that only has 3 disks.

Hi vRhinow,

I suggest you open an independent case as each of the previous cases had a different nature. A few customers reported that cloning/migrating VMs to different storage has solved the issue for them.

Thanks

[MERGED] Backup Fails - VDDK async operations error: 14099

Post by bsieg »

Error: VDDK async operation error: 14009. Value: 0x00000000000036b9 Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.

I am pulling my hair out with this one. We have one ESXi host running 6.7. There are a total of 5 VMs with two different domains. The backup device is a Buffalo TerraStation which is in the same server room as the host but it's connected by network. The Buffalo is in a workgroup and not in any domain.

The one domain which I have been taking up since last year works perfectly fine. The second domain I just setup does not work at all. It starts backing up and it does write files to the Buffalo so permissions are not an issue.


The Buffalo was in the same vlan as the domain that worked so I moved the Buffalo to the vlan that didn't work. That did not resolve the issue. Any help would be appreciated.


Thank you

bsieg,

I've merged your post to the existing thread. Please make sure that nothing is blocking the connection to the ESXi host i.e. you don't have any firewall rules that might affect the connection. If that does not help, kindly, raise a support ticket and share the case ID. Thanks!

It's the community edition so I cannot receive technical support.

Hi Bsieg,

You can get support even with Community Edition, it will be provided on a best-effort basis depending on available support resources.

Do you run backups in Network mode? I see the VDDK error code in the error message pasted above.

I'd suggest to try HotAdd to avoid VDDK read. The data is retrieved by virtual proxy from the directly attached disk instead of travelling through the network link from ESXi to proxy.
By the way, HotAdd supports Advanced Data Fetcher which is based on asynchronous read, this technology usually gives a significant grow of read speed.

Thanks!

If technical support won't help you may just upgrade to the the latest version.

I don´t have the logs, but I belive this was addressed in one of the later versions of Veeam. So please download latest v10 and update your environment.

This issue was the Dell SonicWall. When the job failed and got the VDDK 14009 error, the log in the SonicWall generated the following event.....SonicWall Gateway anti-virus inform smb out of order read/write

To resolve this, I went into the internal settings of the Sonicwall to disable the Gateway AV SMB read/write option as per the article below.

https://www.sonicwall.com/support/knowl ... 070049309/


This finally resolved the 14009 error but then I got a new error message....an unexpected network error occurred. failed to flush buffers.
This was also a SonicWall issue. According to the SonicWall logs, it was picking up false positive virus signatures. I added my two servers to the exclusion list for both the Anti-Spyware and Anti-Virus security settings. I can now finally backup my server!

It is not really best practices to use a firewall between the backup proxy and the VMware environments. You limit the dataflow by the firewall throughput limitation usually.
