When you add Azure AD applications to the backup configuration, Veeam Backup for Microsoft 365 retrieves a list of existing applications from your Azure Active Directory. From this list, you can select as many applications as you need. 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 365 organization with enabled security defaults and select Manage backup applications.
Keep in 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 method 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 the required permissions to Azure AD applications in advance.
