Veeam Backup: open the TCP ports of the firewall

The Veeam Backup & Replication backup solution allows you to create copies and replications of virtual machines based on VMware vSphere and Microsoft Hyper-V hypervisor. This software is very popular in business, for its ease of implementation and reliability. It is possible to replicate the VMs on a SAN, a NAS, a Linux server, a Windows Server or simply a Windows machine with a CIFS share, whether in a local area network LAN or to a remote site. But as with any data transfer over the network, you have to open TCP / UDP ports to communicate between the host and the target. This guide indicates which TCP ports to open on the software or hardware firewall depending on the Microsoft Hyper-V or VMware vSphere hypervisor to receive backups sent by Veeam Backup & Replication.

This is the same mode of operation for Veeam Backup & Replication versions 6, 7, 8 and 9 (including 9.5).

Firewall ports for Veeam Backup Repository 9.0 backup

Concerns connections to Veeam Backup Repository and Backup Proxy in version Veeam B&R 9.0. The software uses the TCP ports 2500 to 5000 for its file transfers from a VMware vSphere or ESXi hypervisor. It is not necessary to open the whole range but each connection will use a port from 2500, which can quickly increase to more than ten ports to manage the exchanges. For example, opening TCP ports 2500 to 3000 will be sufficient for three simultaneous backup jobs.
