The "Backup Configuration" button will create an archive of NBE config folder in $INSTALL_DIR/config-archives. The archive name will have the form yyyy-mm-dd-00h00m00s_NetborderExpressGateway_Version.zip. A pop-up will then appear to let the user download the archive on his computer. Note that if the browser is configured to automatically download files, no pop-up window will appear. If the download is canceled, the archive could still be downloaded from the File Browser tab.
