Mount

1. Mount the external device automatically, here it is a NAS available at the address/path //CL-NAS/home mounted to /backup. Add following line to /etc/fstab:

//CL-NAS/home         /backup       cifs  defaults,rw,credentials=/etc/nas-credentials,x-systemd.automount 0 0

To mount a usb device instead, have a look at this

This will keep the external device mounted at the specified location, even after reboots and crashes.

2. Add a credential file at /etc/nas-credentials:

Install Raspberry Pi Power Button Script

Make sure you have a raspberry pi. (This script is tested with the raspbian dist on a series 3 model B+)

DISCLAIMER: Look at the script for the PINS and PORTS used. You can change it in the section Configuration if you like.

1. Download the raspberry-pi-power-button-script.py script, name something like shutdown.py and put it somewhere publicly available.

2. Make script executable with chmod +x <absolute_path_to>/shutdown.py.
