After upgrading to v 12.3.2.3617, I have found a default setting which breaks certain elements of VBR and VCC.
When creating an object storage repository, Automatic bucket creation enabled is the default!
Step 4. Specify Object Storage Settings - User Guide for VMware vSphere


Leaving this option on creates issues when using this repository for the following backups.
- Veeam Cloud Connect

- EntraID
Configuring Log and Cache Repositories - User Guide for Microsoft Entra ID

- Unstructured data backup

- The problem is that going back and unchecking this option does not actual disable it.
- In addition, removing the repository and re-adding it with the option disabled also does not disable it.
- The repository needs to be created the first time with this option disabled.
- This is a major issue if one is unaware of the consequences of this option and just click “Next” through it or if repositories are being created with a script and this option is not disabled.
- If the repository is created with that option disabled, it can be enabled afterwards
I hope this discovery helps you before you bang your head against the wall trying to fix it. I also hope that Veeam changes this to be disabled by default.
Thanks,
Hin
