Challenge
When adding an Object Storage Repository, the following error occurs:
The selected bucket supports blob versioning.
Select a bucket with disabled blob versioning.
Cause
This issue occurs because the cloud storage has Versioning enabled.
Starting with Veeam Backup for Microsoft 365 v7, when creating an Object Storage Repository, the software verifies if Versioning is enabled. If Versioning is detected at the object storage level and the immutability option is not enabled in the repository settings, the creation of the Object Storage Repository is blocked. This check aims to prevent two issues: (1) data corruption caused by a Versioning rollback altering backup files and (2) unmanaged versions.
Solution
For Veeam Backup for Microsoft 365 version 8.x
When adding an object storage repository and this error occurs, consider the following:
If the Object Storage Repository will be used to store primary Backup data or secondary Backup Copy data, enable the immutability option within the repository settings.
If the Object Storage being added was previously used to store primary Backup data using Veeam Backup for Microsoft 365 version 6 or 7, and must now be added as an Object Storage Repository in Veeam Backup for Microsoft 365 v8, please create a Veeam Support case for assistance.
