Backup Proxy Servers

A backup proxy server is an architecture component that conducts all read and write activities during data backup and restore, routes backup traffic, handles data compression and encryption and sends email notifications about backup and backup copy job results.

Consider the following:

  • By default, the role of the backup proxy server is assigned to the machine where Veeam Backup for Microsoft 365 is installed. The default backup proxy server is displayed as Local backup proxy in Veeam Backup for Microsoft 365.
