Just a simple back up script and my cron entry. This script will check to see if your USB device exist. If so, it mounts, it rsyncs, it echo’s a date and a “complete” string into a file then unmounts the drive. If the USB device don’t exist, it echos a fail into a file.
My script runs every night 1 minute after 3am.
*Reason I have unmount is so I can just yank it out whenever I want. Also, with any *nix, there is more than one way to skin a cat, this is my way I figured out on my own.
