If you use automatic mode selection, Veeam B&R will scan the backup proxy configuration and its connection to the VMware infrastructure to choose the optimal transport mode. When configuring Backup Proxy settings, you can manually select a transport mode or let Veeam B&R select the most appropriate mode automatically. The transport mode can be defined in the settings of the Backup Proxy that performs the job.
Veeam Data Mover service is responsible for reading data on a Backup Proxy server. For reading data, Veeam B&R offers the following modes (starting with the most efficient): You can explicitly select the transport mode or let Veeam Backup Server automatically choose the mode. If the VM disks are located on the SAN storage and the SAN storage is added to the VBR console, the backup proxy can also use the Backup from Storage Snapshots mode. Depending on the type of Backup Proxy and your backup architecture, the Backup Proxy can use one of the following data transport modes: Direct Storage Access, Virtual Appliance or Network (for VMware, VBR leverages VMware vStorage APIs for Data Protection – VADP). The transport mode is a method that is used by the Veeam Data Mover Service to read VM data from the source and write VM data to the target.

The role of a Backup Proxy can be assigned to a dedicated Windows server (physical or virtual) in your virtual environment (physical on the picture below). As the data handling task is assigned to the Backup Proxy, the Veeam Backup Server becomes the point of control for dispatching jobs to proxy servers. In particular, the backup proxy tasks include retrieving VM data from the production storage, compressing and sending it to the backup repository (for example, if you run a backup job) or another backup proxy (for example, if you run a replication job).
A Backup Proxy is an architecture component that sits between data source and target and is used to process jobs and deliver backup traffic. To take the workload off the Veeam Backup Server, Veeam B&R uses backup proxies. This scenario is acceptable for virtual environments where few backup jobs are performed, in large-scale environments, however, the workload on the Veeam Backup Server will be significant. So, by default Veeam Backup Server plays Backup Proxy role.
That is, when you run a backup, replication, VM copy, VM migration job or perform restore operations, VM data is moved from source to target through the Veeam Backup Server. When Veeam B&R is initially installed, the Veeam Backup Server (named “Management Server” on the picture below) coordinates all job activities and, until you deploy a Backup Proxy (Veeam Transport) handles data traffic itself. The following article shows the flow matrix and ports that must be opened to ensure proper communication of the Backup Server with backup infrastructure components… Note: Veeam Help Center section covers typical connection settings for the backup infrastructure components (used ports). Understand Veeam core components and their communication is very useful especially to improve the security of your architecture (cybersecurity and compliance). Hi, this post (Veeam B&R: Flow matrix and Transport modes) is focused on Backup Proxies interaction and ports requirements.
