Copy all csv-files from the data folder to the last added usb-device. Implemented as a cron job, this can be used for automated data logging/ data backup. We used this script in the remote areas of the Amazon Rain Forest to do regular backups of our sensor stations.

# This script is the main script to automatically mount
# a USB device to the data folder and copy the required data
# Data folder: /your/data/folder/path/  (the folder where the data is stored)
# Target folder: /media/usb/               (the mounted USB folder, where the data is copied to)
