What follows is a nice shell script that is used for backing up
important directories. If you create a /bkup directory on a separate
drive, this can be used to recover from a hard drive crash. Add this
script to the crontab to run a backup every night and your in business.
And change/add directories on the bottom. It rotates the directories
around and removes the oldest up to 7 days. Simple, yet handy. :)
