I can't backup VM guest. When backup job running 60% it failed and I found this error. (Veeam Version 8)

Code: Select all

Error: VDDK error: 21036749815809.Unknown error
Failed to upload disk.
Agent failed to process method {DataTransfer.SyncDisk}.
Exception from server: VDDK error: 21036749815809.Unknown error
Unable to retrieve next block transmission command. Number of already processed blocks: [172772].
Failed to download disk.

Please tell me how can I fix it ?

This error looks to be coming from inside of VMware vStorage API... do you have this error every time you do a backup? Have you tried switching to different backup modes (network, hotadd, SAN)?

I had the same error on one of our VM's after the upgrade to v8, I just ran it on network mode and it completed fine, I wanted to see if it was fixed in patch 1 before I logged a ticket. it only happened on one VM out of 500 so I was not too worried. I will let you know if patch 1 fixes it.

If there were no tickets on this problem, then I doubt it has been fixed That is why we always ask to open a support case.

Same issue here on our Exchange server. All other jobs are running fine. Have reset CBT multiple times. Using SAN direct mode. Coming from EMC NetWorker using exact same servers and it backs Exchange up just fine.
