Configuring HTTP Proxy for Backup Appliances

To manage the inbound and outbound traffic of your backup appliance, you can configure an HTTP proxy. Using an HTTP proxy provides access to the required services and resources, enhancing the security, efficiency and privacy of your backup environment.

Note

The provided instruction does not apply to worker instances that are deployed to perform backup and restore operations, as well as to the Veeam Updater service. To learn how to configure an HTTP proxy for the Veeam Updater service, see Configuring Web Proxy.

To configure connection to the internet through an HTTP proxy, do the following:

On the Azure VM on which Veeam Backup for Microsoft Azure is installed, open the configuration file used to set global environment variables by running the following command in a terminal window:

sudo nano /etc/environment

In the configuration file, do the following:

Add a connection to an HTTP proxy server by setting the http_proxy="http://host:port" variable.
Add a connection to an HTTPS proxy server by setting the https_proxy="http://host:port" variable.

The https_proxy variable must have the same HTTP proxy address specified in its value as the http_proxy variable.

Important

Veeam Backup for Microsoft Azure does not support access to resources through HTTPS proxy. The https_proxy variable is used only to ensure that the HTTPS traffic is sent to the HTTP proxy.

[Applies only if the proxy server requires authentication] To authenticate against the proxy server, set the http_proxy="http://username:password@host:port" or the https_proxy="http://username:password@host:port" variable.
Specify the IP addresses that are not required to use the proxy to connect to your backup appliance by setting the NO_PROXY="<addresses>" variable, where <addresses> is a comma-separated list of necessary IP addresses or DNS names.

The list must include the following addresses: 169.254.169.254 — the IP address of the Azure Instance Metadata Service (IMDS), localhost and 127.0.0.1 — the DNS name and the IP address of your local machine.

Save the changes and close the configuration file.

To apply changes, reboot the Azure VM on which Veeam Backup for Microsoft Azure is installed.
Use either Azure network security groups or firewall rules to allow inbound and outbound access to the Azure VM on which Veeam Backup for Microsoft Azure is installed for all necessary IP addresses including those of your backup server, the HTTP proxy itself, IMDS, and so on.

Note that Veeam Backup for Microsoft Azure version 8 does not support connection to email server specified in the notification settings through an HTTP proxy. If you plan to configure these settings, you must allow inbound and outbound access to the Azure VM on which Veeam Backup for Microsoft Azure is installed for the necessary email server.

Important

For Veeam Backup for Microsoft Azure to be able to create and manage backup repositories when using the configured HTTP proxy, open a support case.
The provided instruction applies to backup appliances that operate public virtual networks. If you want to configure an HTTP proxy for a backup appliance deployed in a private environment, open a support case.
