OneDrive backup - Failed to download block in time

[albertwt]

When backing up the OneDrive of my users, some of them have this error for example:

Processing OneDrive Big Boss (https://corporatedomain-my.sharepoint.c ... porate_com) finished with warning: Failed to backup item: /personal/big_boss_corporate_com/Documents/Documents/Leadership.epub, Failed to download block in time: 00:29:59.9949654.

How do you resolve the issue above when the file is available at the OneDrive and can be opened with no issue?

[Mike Resseler]

Hmmm, I have no idea what that message means to be honest. It seems to be an issue we cannot download it in time, which normally I think should not be an issue.

Please create a support call for this. Maybe you can add already whether it is always the same files that fail, or it is random?

Put the case ID here in the forum for further reference if possible

Hi, i have the same warning for some objects (CaseID #07470826). Support answered with this process:

1. *Verify Direct Download*:
- Open the affected OneDrive or SharePoint Online site in a web browser.
- Navigate to the specific file mentioned in the warning.
- Attempt to download the file directly from the site to ensure it is accessible and not corrupted.

2. *Refresh Metadata*:
- If the file can be downloaded directly, try refreshing its metadata by removing and then re-uploading the file to the same location.
- This can help resolve any underlying issues with the file's metadata that might be causing the backup to fail.

3. *Retry the Backup Job*:
- After refreshing the metadata, retry the backup job to see if the issue persists.


I am currently in the process of triggering the warnings in cooperation with the organization concerned. It has already worked out with one warning, but I am still waiting for feedback on the specific steps to be taken.

We are also getting these on OneDrives files that previously was marked "Item may have a virus reported by the virus scanner plug-in"

The change happened after updating to version 8.0.4.29 - logged case #07496131

We got thousands of this warning " Failed to download block in time", and something those files are infected or false postives. Since v8 we didnt see yet the old message "Item may have a virus reported by the virus scanner plug-in" .

Wanna know if this has warning has been replaced.

Mike, can anyone of your Team clarify those messages, we found this messages in keygens , cracks , autoclicker from customers that obviusly are malware. But in V7 this error will be advice as posible virus warning, right know looks like block download.

Sample:

11/11/2024 6:57:22 :: Processing site https://XXXXXXXX.sharepoint.com/sites/XXXXXX finished with warning: Failed to backup item: /sites/XXXXXX/Documentos compartidos/XXXXX/Escritorio/medicina_Civil 3D 2012 64bits/Keygen Autodesk 2012 x64.exe, Failed to download block in time: 00:29:59.9992235. :: 0:30:09

Hi Manuel,

You're absolutely right; v8 should not even try to download such files, and RnD is already working on a fix. Can you provide me with your support case ID?

[edh]

Hi @Polina,

Yes, Case #07499179 if your team seek in the logs , will get a ton of examples.

Hi,

[Polina]

Yes, please share

[MarkBoothmaa]

[andre.simard]

Case #07470420

[Polina]

The hotfix is now available via support.

[edh]

@Polina, is this hotfix in version 8.0.5.20_20241112 ?

[Polina]

Hi Manuel,

No, the fix wasn't ready when it was released. You can get a hotfix via support and install it on top of 8.0.5.20.
Later on, we will include it in the next v8 patch.

[edh]

Thx , requested to support.

[albertwt]

Yes, confirmed, the issue is still persisting in the Veeam Backup for Microsoft 365 8.0.5.20.

[Polina]

@albertwt

Please contact support to get a hotfix. You can install it on top of 8.0.5.20.

Thanks!

[albertwt]

Sure, THank you @Polina.

[edh]

I can confirm that patch 8.0.5.2002 works again as expected and now items are reported as " Item may have a virus reported by the virus scanner plug-in ".

We are seeing a lot of these warnings across all of our tenants.
We have an open support case (#07567298).
We installed patch 8.0.5.2002 when it was suggested by Support, but that did not resolve the warnings for us.
Last week we updated to 8.1.0.305 as suggested by support, that did not resolve the issue either.
Throughout the case we have added multiple custom lines to our source tag in the proxy.xml files as suggested by support:
<Source SkipOneNoteTimeoutWarning="true" SkipVirusWarning="URL_PATH" SPDownloadMaxRetryWait="30" />
So far nothing has helped. If anything we are seeing more and more "failed to download block in time" warnings.

Has anyone found a working solution for this issue please?

Thank you!

[Polina]

Hi Sieben,

The working solution was released in build 8.1.0.305 (v8.1) and until today I wasn't informed of any issues. Please stay in touch with our support engineer; meanwhile, I'll ask the team to investigate it further.

Thanks!

Hello Polina,

Thank you!

I will await further response from support, was just wondering if anyone had received a fix that was not mentioned in our case yet.
I'll make a summary of what has been suggested in our case so far, maybe it helps anyone else find a working solution for them, or suggest a solution that was not mentioned to us yet:
- Install patch 8.0.5.2002
- Add "<Source SkipOneNoteTimeoutWarning="true" />" line within Archiver block in proxy.xml files
- Install patch 8.1.0.305
- Increase the retry count of the job. The default value is 3 retries every 10 minutes. Double those values and change to 6 retries every 20 minutes.
- Create additional Veeam Backup for Microsoft 365 Entra ID Applications (Support suggested 5-10)
- Add <<CONFIG PARAMETER REMOVED BY MOD>> line within Archiver block in proxy.xml files (merged into previous Source line so only 1 Source line exists)
- Reboot Veeam Backup for Microsoft 365 server (I believe this was suggested because we had not rebooted yet since the upgrade to patch 8.1.0.305 and/or most recent changes to proxy.xml files).

Hello Sieben,

I have removed the second configuration parameter from your comment.
Such configuration changes should only be made after opening a support case and under the guidance of our support team. The first parameter is an exception, as we provide the key with an official KB article: https://www.veeam.com/kb4529

Best,
Fabian

Hello Mildur,

Thank you. I will keep that in mind for future posts

Best regards,

[admd]

Hello,
We are also looking for a fix for this error

[Sieben]

Hello,

We are still working with support to find a solution.

Support suggested an additional change to proxy.xml files to increase the download timeout value to 24 hours but now we have about 30-40 jobs that run for 24 hours and still give a "failed to download block in time" warning.

We also have a testjob with just 1 user's OneDrive that somehow has been running for 48 hours now

[Sieben]

FYI we received a patch from Support to run on top of 8.1.0.331 which seems to have resolved the issue!

[dasfliege]

If you're talking bout patch to 8.1.0.2048, we've received the same and "failed to download block in time" are mostly gone.
However, we now have quite a lot of "Item has changed during the backup". Seems to me like veeam is now giving up faster on items beeing edited instead of waiting for them to become readable?
