Design

Depending on an organization’s needs, Veeam Backup for Microsoft 365 can be deployed in various ways. For small environments, a single-server setup may suffice, while larger environments can benefit from scalability by running on multiple servers. The implementation design of Veeam Backup for Microsoft 365 comprises several components.

Veeam Backup for Microsoft 365 Server
Veeam Backup for Microsoft 365 Proxy Servers
Veeam Backup for Microsoft 365 Repositories
Veeam Backup for Microsoft 365 REST API Service
Veeam Backup for Microsoft 365 Restore Portal
Veeam Explorers

To scale the environment multiple proxies can be implemented (scale-out) and process multiple tasks simultaneously. For storing the backup data multiple repositories can be deployed and configured.

In contrast to Veeam Backup and Replication, the Proxy Server and Repositories within Veeam Backup for Microsoft 365 are directly coupled in a One-to-Many relationship. A Repository is connected to a single Veeam Backup for Microsoft 365 Proxy server, and one Veeam Backup for Microsoft 365 Proxy server can handle multiple repositories.

If you plan to expose the Restore Portal to the public internet or expect high usage by end-users, consider configuring the REST API and Restore Portal on a separate machine. This approach can enhance security and better align with your performance needs.
