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 » Feb 06, 2019 12:40 pm

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.

Kindly, keep working with our support team directly. Also, don't post log snippets here (it's against the forum rules). Thanks!

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.
