I have an idea for the script. I’ve been looking for a way to backup the SD card easily. The problem with most tools now is that if you’ve already expanded the partition to the full size of the card, you create really large backups. There doesn’t appear to be a simple way (such as the expand_rootfs option in the raspi-config) to do this.

Initially thought of requesting a command in the script to shrink the partition so that I could use a third party tool to backup, but perhaps we should take it a step further.

TL;DR
It would be nice to have an option in the script that would create a compressed *.img backup of the SD card and dump it in a directory where you can SCP the image off of it. The option could be called Backup the SD card. There would obviously need to be a check that checks to see if there is enough space available first.
