When you add Azure AD applications to the backup configuration, Veeam Backup for Microsoft Office 365 retrieves a list of existing applications from your Microsoft Azure Active Directory. From this list, you can select as many applications as you need. Each added application helps you reduce throttling during a backup of Microsoft SharePoint Online and Microsoft OneDrive for Business data. For more information about Azure AD applications, see this Microsoft article.
To add Azure AD applications to the backup configuration, do the following:
- Open the Organizations view.
- In the inventory pane, right-click a Microsoft Office 365 organization with enabled security defaults and select Manage backup applications.
Mind that the Manage backup applications option is available only for organizations added using modern app-only authentication. For organizations added using either basic authentication or modern authentication with legacy protocols allowed, you use the Manage backup accounts option. For more information, see Adding Accounts.
- In the Backup Applications Manager window, click Add.
- In the Add Applications window, select Azure AD applications that you want to add and click Add.
Make sure to manually grant applications required permissions in advance.
Also, mind that Veeam Backup for Microsoft Office 365 ignores an Azure AD application that you use when adding your Microsoft Office 365 organization; such applications are never used to reduce throttling.
- Click Not configured next to each added application to configure an SSL certificate that you want to use for secure communications between Veeam Backup for Microsoft Office 365 and your Azure AD application.
- In the Select Certificate wizard, select an SSL certificate. For more information, see SSL Certificates.
Before selecting a certificate in Veeam Backup for Microsoft Office 365, you must assign this certificate to the application on the Azure portal. For more information, see this Microsoft article.
