Creating Applications

When you create a new Azure AD application, Veeam Backup for Microsoft 365 automatically registers this application in Azure Active Directory of your Microsoft 365 organization. After you create an application, Veeam Backup for Microsoft 365 automatically adds this application to the backup configuration. For more information about Azure AD applications, see this Microsoft article.

To create Azure AD applications and add them to the backup configuration, do the following:

  1. Open the Organizations view.
  2. In the inventory pane, right-click a Microsoft 365 organization with modern app-only authentication 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.
