Veeam365 and problem with Object version invalid

[jfrobs]

31.07.2025 05:55:38 :: Failed to process OneDrive: "The collaborator name". Cannot read the object from object storage because the object version is invalid: -1890210654. :: 0:00:32

I am encountering an issue when backing up veeam365 on my Object first S3 appliance.

I only have this for a single user's OneDrive...and unfortunately, I am not sure what to do.

Any ideas?


Veam365 last version : 8.1.2.180

Hello,

That sounds like a technical issue. We cannot investigate such issues through a forum topic.
Please provide a support case ID for this issue, as requested when you click New Topic. Without case number, the topic will eventually be deleted by moderators.

The error message could mean that there is a problem with the objects on your object storage. Our support will be able to investigate the root cause for you.

Best regards,
Fabian

Thank you for your feedback.

I work with our partner in Switzerland, so I will ask them to open a ticket for me.

You're welcome.

I found your case number and will keep an eye on it.
May I ask, are there any lifecycle policies configured on the object storage?

Best regards,
Fabian

I keep the data for 5 years and immutability for 30 days.

The strange thing is that I only have this problem with one item... a user's OneDrive.
Everything else works perfectly.

Hi,

I asked because we have seen similar messages when Object Storage lifecycle policies were used.

These policies are managed directly on the object storage and can modify objects outside of Veeam products. This may result in backup and restore issues, which is why lifecycle policies are not supported.

Let's wait for our support team to investigate the logs from your backup server.

Best,
Fabian

Hello,

I answered a few questions from support this morning.
I had already uploaded the logs, but they must not have seen them.

At Objectfirst, there aren't many options:



Only versioned for put immuability on the bucket.

And versioning is active on both sides.

[Mildur]

Yes, I have the same settings in my lab with Object First.
As far as I know, Object First does not have lifecycle policies, so you're good from that perspective.

Let's wait and see what support finds out.

Best,
Fabian

We ran quite a few tests with support.

In the end, if I create a new bucket, everything is OK.

For me, recreating an empty bucket and redoing a full backup of our tenant is not a solution.
I have no desire to multiply backup buckets...

We need to be able to delete the data corresponding to the user's OneDrive and run a backup of the tenant in order to have a clean backup of their OneDrive.

So yes, I will lose the old backups for this specific user, but that's okay.

However, I don't know how to do this, and in my opinion, with 30-day immutability, we'll have to wait before we can delete the files.

Support hasn't responded to me on this point... I'm waiting for a response, but I get the impression that they don't know themselves.

Hi,

There is a cmdlet available to delete backups for a single user, and you can specify it to remove only OneDrive backups.

However, due to the error message you received, I can't guarantee that the backup will be deleted as expected. It's highly recommended to verify this cmdlet with your support engineer before proceeding.

Remove-VBOEntityData

Code: Select all

Remove-VBOEntityData -Repository $repository -User $user -OneDrive

Best regards,
Fabian

[jfrobs]

Yes....but it doesn't work...

I just tested it and I still get the same error message :




This is the tutorial from support :

If you would like to delete the user data, please open an elevated Veeam Backup for Microsoft 365 PowerShell and run the below command

$repository = Get-VBORepository -Name "NAME OF THE REPOSITORY"
$user = Get-VBOEntityData -Type User -Repository $repository -Name "NAME OF THE USER"
Remove-VBOEntityData -Repository $repository -User $user -Mailbox -ArchiveMailbox -OneDrive -Sites

I don't know when the user's OneDrive was last backed up, so it's difficult to know when the immutability will expire.

Hi jfrobs,

Am I correct that you are using an immutable repository? In such a case, the error you see in PowerShell is expected because the Remove-VBOEntityData is restricted on immutable repos. HelpCenter will soon be updated with a corresponding note, since it seems to be missing atm.

[jfrobs]

I opened a ticket with Objectfirst with the support exchanges with Veeam.

Yes, the S3 repository is an object with immutability set to a number of days.

What seems logical to me is that after the days have elapsed, the immutability on the object should no longer be active.

But apparently, deletion by Veeam remains impossible.

And based on your message, it seems that since the S3 is an immutable S3, there is no possibility of deletion via the command line, even after the immutability date has expired.

So I think the only solution is to delete it directly from the object storage using command lines or a tool specific to ObjectFirst.

I will wait for a response from Object First, who work closely with Veeam, to find a solution, as I don't think I will be the only one in this situation in the coming years.

Another option could be to remove the object from any backup tasks and retention will do the job in its due time according to your settings.
