Appendix E. Configuring HTTP Proxy for Backup Appliances

To manage the 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.

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

1. Connect to the EC2 instance where Veeam Backup for AWS is installed. To do that, run the following ssh command in a terminal window:

2. To open the configuration file used to set global environment variables, run the following command in a terminal window:

3. In the configuration file, do the following:

1. To configure a proxy server, set the http_proxy="http://host:port" variable.
2. [Applies only if the proxy server requires authentication] To authenticate against the proxy server, set the http_proxy="http://username:password@host:port" variable.
3. To specify the IP addresses that are not required to use the proxy to connect to your backup appliance, set 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 Instance Metadata Service (IMDS), localhost and 127.0.0.1 — the DNS name and the IP address of your local machine.

4. Save the changes and close the configuration file.

4. To apply the changes without rebooting EC2 instance, run the following command:
