Ports

As Google Cloud Plug-in for Veeam Backup & Replication is installed on the same machine where Veeam Backup & Replication runs, it uses the same ports as those described in the Veeam Backup & Replication User Guide, section Ports. In addition, Google Cloud Plug-in for Veeam Backup & Replication also uses ports listed in the following table.

From	To	Protocol	Port	Description
Workstation web browser	Backup appliance	TCP/HTTPS	443	Required to access the Web UI component from a user workstation.
	Backup appliance	TCP/HTTPS	13140	Required to communicate with the REST API service running on the backup appliance.
	Worker instance	TCP/HTTPS	443	Required to access the file-level recovery browser running on a worker instance during the file-level recovery process.
Backup appliance	Ubuntu Security Repository (security.ubuntu.com)	TCP/HTTP	80	Required to get OS security updates.
	Veeam Update Repository (repository.veeam.com), Amazon CloudFront (cloudfront.net, amazonaws.com)	TCP/HTTPS	443	Required to download available product updates, worker deployment packages and restore utilities. Note: Veeam Update Repository uses the Amazon CloudFront service to distribute traffic when downloading product updates.
	SMTP server	TCP	587	Required to send email notifications. Note: You cannot use the TCP port 25 that is most commonly used by SMTP servers — the port is always blocked by Google Compute Engine. For more information, see Google Cloud documentation.
	nginx web server (nginx.org)	HTTPS	80/443	Required to upgrade the backup appliance.
	PostgreSQL Apt Repository (apt.postgresql.org)	HTTPS	80/443	Required to get PostgreSQL updates.

Note

When you deploy a backup appliance from the Veeam Backup & Replication console, Veeam Backup & Replication automatically creates firewall rules for the required ports to allow communication between the backup server and the appliance components.
