In order to upgrade your firmware via the command line, please follow this guide which explains everything in-depth: https://wiki.teltonika-networks.com/view/Firmware_upgrade_via_command_line

Everything that is written about firmware upgrade via command line, applies to backup too as it uses the same sysupgrade command to upload configuration.
