The novice asked the backup master: "How often should I backup my files? It has been a month since my last backup."
The master replied: "Just as night follows day, and Autumn follows Summer, so should backups follow work. As you work, so should you backup that work."
The novice said: "I work each day".
The master replied: "Then you should backup each day".
The novice replied: "I agree, but right now I haven't got time to make a backup, as I have too much work to do."
Upon hearing this, the master fell silent.
