Azure File Shares no longer backing up

[CaptinJack]

Hi Guys,
I've got a bit of a weird one which I am 99% sure is related to permissions somehow.

We have two file shares in different storage accounts which we have backed up/snapshotted successfully for several years using Veeam backup for Azure.

This morning, I updated B&R which the appliance is linked to and it performed an update to 8.0.1.182 from 8.0.0.377.

Ever since the update, we cannot see the file shares anymore within the configuration. We can still see the storage accounts.

Looking at the logs, I can see the job thinks the shares have been deleted:

Code: Select all

[10.09.2025 09:00:13.782] Info     38 (1) Expanding the policy (priority: 2) into the list of databases...
The items to be expanded are: 
	- name (optional): profiles, ID: *removed*, type: FileShare; the item is deleted from Microsoft Azure

Where as, just an hour earlier (before the update) it worked fine:

Code: Select all

[10.09.2025 08:00:09.012] Info     81 (1) Execution plan for policy *backup plan* (ID: *Removed*) has been created. Items to protect:
	- FileShare: profiles (ID: *removed*, Azure ID: /subscriptions/*removed*/resourcegroups/*resourcegp*/providers/microsoft.storage/storageaccounts/*removed*/fileservices/default/shares/*sharename*)
[10.09.2025 08:00:09.017] Info     77 (1) Synchronizing the latest policy resources for the policy *Backup Plan* (ID: *removed*)...
[10.09.2025 08:00:09.020] Info     81 (1) Synchronization of the latest policy resources for the policy *Backup Plan* (ID: *removed*) completed:

Looking further into the appliance log, I am also seeing this:

Code: Select all

[10.09.2025 10:55:54.525] Warning  65 (1) Warning: Failed to obtain the blob service properties for the storage account (ID: /subscriptions/*removed*/resourcegroups/*resourcegp*/providers/microsoft.storage/storageaccounts/*storageaccountname*). Blob is not supported for the account.
Status: 400 (Bad Request)
ErrorCode: FeatureNotSupportedForAccount

Content:
{"error":{"code":"FeatureNotSupportedForAccount","message":"Blob is not supported for the account."}}

Has something changed in this update that no longer supports the storage accounts/file shares that we successfully backed up before (one of them for 3 years)?

Thanks

(I have removed sensitive data from the logs)

EDIT: I should add, I have done a permissions check which all report fine.

Just to add, the storage accounts are premium fileshare and contain AVD profile disks (not general purpose v2, as these were far too slow).
