Using proxy server in FTP Backup

The proxy server acts as an intermediary between a computer and the Internet. It is associated with a gateway server (that separates the local network from the outside network) and a firewall (that protects the network from outside intrusion).

Many companies use proxy servers to provide security and/or restrict access. The proxy server must be configured manually in Backup4all using the FTP Advanced Settings section.

Setting Backup4all to backup to FTP using proxy

  1. In Backup Properties->Destination->FTP Server->Custom Configuration->Edit Configuration (or the Tools->Options->FTP window if you're using a predefined FTP configuration for the current backup job) after entering the details of the destination FTP (host, username, password) go to the Advanced section
  2. Select a Proxy Type from the available options:
    • None - Sends the User name and optional Password for the FTP server as entered in the FTP window
    • Send command USER - Sends the User name and optional Password defined in the proxy settings, followed immediately by the User name and optional Password for the FTP server.
    • Send command SITE - Sends the User name and optional Password defined in the proxy settings, the SITE command with the Host value, and the User name and optional Password for the FTP site.
    • Send command OPEN - Sends the User name and optional Password defined in the proxy settings, sends the OPEN command with the Host value, and the User name and optional Password for the FTP site.
    • USER user@firewalluser@hostname / PASS pass@firewallpass - Sends the command USER user@proxyuser@host, then the command PASS pwd@proxypwd, or optionally PASS pwd.
    • Transparent - Sends the User name and optional Password defined in the proxy settings, followed immediately by the FTP server User name and optional Password.
  3. Enter the name or IP address for the proxy server (firewall) and the port in the Host name and port number (host:port) field. The format is proxy:port, e.g. localproxy:8080
  4. Enter the user name and password needed for this proxy connection in the respective fields (User name/Password).
  5. Press OK and then test the connection.
