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:
- Open the Organizations view.
- 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.
- In the Backup Applications Manager window, click Create.
The Create Application wizard runs.
- Enter a name that you want to use for the Azure AD application and specify an SSL certificate for secure communications between Veeam Backup for Microsoft 365 and your application. For more information on how to install a certificate, see Installing SSL Certificates.
Veeam Backup for Microsoft 365 will automatically register the specified certificate in your Azure Active Directory and assign this certificate to the Azure AD application. In addition, Veeam Backup for Microsoft 365 automatically grants the Sites.FullControl.All permission to the application.
If you want to create more than one Azure AD application, select the Use the same name and certificate to create N applications check box and specify how many applications Veeam Backup for Microsoft 365 must create. Applications may have the same name, however, each application always has a unique identification number. You can create maximum 100 applications per wizard session. If you need to create more than 100 applications, you can click Create and repeat the steps.
