Important

  • As Veeam Backup for Microsoft Entra ID is installed on the same machine where Veeam Backup & Replication runs, it also uses the same ports. To be able to use the tenant backup copy feature, you must configure the ports listed in the Backup Repositories section of the Veeam Backup & Replication User Guide.
  • Veeam Backup for Microsoft Entra ID does not support remote backup proxies — instead, the backup server performs the role of a general-purpose backup proxy.
