According to Microsoft Message ID MC1011142, app-only authentication for Microsoft Graph APIs will be retired on March 31, 2025. Barracuda Cloud-to-Cloud Backup currently relies on app-only authentication. As a result of this change, Barracuda Cloud-to-Cloud Backup will no longer be able to restore OneNote Notebooks to Microsoft 365. However, users can still export OneNote Notebooks from Barracuda Cloud-to-Cloud Backup as an alternative recovery option. If a restoration attempt is made for a OneNote Notebook, it will fail, and a warning message will be generated in the job report.

Use the Restore page to view your backed up data and to export and restore your data.
