How Restore Portal Works
The following components are involved in the Restore Portal operation:
- Veeam Backup for Microsoft 365 server
- Veeam Backup for Microsoft 365 REST API Service
- Microsoft 365 organization
- Restore Portal
- Veeam Backup Proxy for Microsoft 365 Service
Veeam Backup for Microsoft 365 uses REST API and Azure AD application when authenticating users to Restore Portal with their Microsoft 365 user account credentials. REST API authorization is based on the OAuth 2.0 Authorization Framework. For more information on how to create and configure Azure AD application to access Restore Portal, see Creating or Configuring Azure AD Application.
