User Guide

Mail Backup as a Service

Starting with Veeam Backup & Replication 9.5 Update 3, Veeam supports flexible application integration options for Veeam Cloud & Service Providers (VCSP) who offer hybrid or Exchange Online organization data backup to their tenants by means of Veeam Backup for Microsoft Office 365. Possible Veeam solution components deployment and interaction for this scenario is illustrated in the figure below.

Mail Backup as a Service 

  1. When a user on the tenant side initiates mail restore, Veeam Explorer for Microsoft Exchange (VEX) communicates this restore request to Veeam Backup for Microsoft Office 365 management server (VBO365).

2,3 Management server detects the proxy server responsible for processing tenant data and the corresponding associated repository storing the backup.

  1. Backup data is transferred to tenant via Veeam Cloud Gateway, and user on the tenant side performs the selected restore scenario (export, restore, saving or sending by email). Veeam Cloud Gateway settings are configured in Veeam Backup & Replication and stored in its configuration database.

Performing Restore Operations using RESTful API

A service provider can use Veeam Backup for Office 365 RESTful API to build a web portal that will allow tenants to browse and restore their backups without using Veeam Explorer. An example of creating a custom web-based portal for working with RESTful API can be found here: If preferred, tenants then can use HTTPS requests to access their backups via Veeam Backup for Office 365 RESTful API and perform restore operations (see RESTful API reference for details).
