Upload operation of .tmp files using VIX after starting data transfer task

Post by Asahi »

Hi,

Can someone please help me with the AAIP quiescence process via VMware Tools (VIX). :D
I understand that in an environment where there is no RPC communication with the VM, the runtime process is uploaded to the guest OS via VIX for quiescence processing.
https://helpcenter.veeam.com/docs/backu ... ml?ver=110

Once the quiescent process is finished, the data transfer task would then be executed.
The following log indicates that the data transfer task has started.
===
[26.05.2022 20:25:35] <43> Info [AP] (4b59) command: 'Invoke: DataTransfer.SyncDisk
===

However, looking at the task log, it appears that it is continuously uploading .tmp files to the guest OS and ESXi hosts even after the data transfer task has started.
It is always logged between "VSSControl: KeepSnapshot started" and "VSSControl: KeepSnapshot completed", which is running continuously until the data transfer task is completed.

Code: Select all

I was under the impression that the VSS quiescence process is complete before the data transfer task starts, so the files are not continuously uploaded to the guest OS. :shock:
Will the .tmp file still be uploaded after the data transfer task is started?

Hello,

correct.

before doing any investigation... do you see any technical issue, or is it a question about log file interpretation of the "'Invoke: DataTransfer.SyncDisk" command?

If there is a technical issue, what is the case number for that problem?

Thanks,
Hannes

Hi Hannes,

Thank you for reply.

I simply wanted to confirm that the behavior of uploading the .tmp to the VM and ESXi hosts after the data transfer is performed is a spec behavior of Veeam.
If it is a specificate behavior, I do not understand why the file upload is necessary.

Hello,
If there is no problem, then it sounds good to me :-)

It makes little sense trying to interpret that kind of log entries. Please understand, that we keep some information "internal only".

Thanks for your understanding,
Hannes
