While it doesn't help with the primary issue, I'd recommend running such tasks from a screen <https://www.gnu.org/software/screen/> -- or tmux <https://github.com/tmux/tmux>, if you prefer -- session. This is almost always the first thing I launch when remotely logging onto a server, as they not only insulate terminal session from being killed if the network connection is lost, but also also allows you to transparently disconnect the session and reconnect later.

Both are included in pretty much every Linux distribution, although they may not be installed by default.
