On one hand, there are legal departments that advise keeping everything forever, and on the other are those that recommend deleting everything as a matter of policy as soon as possible — whacking away at files and folders on your file servers like a drunk landscaper whirling a weed whacker around your yard. Meanwhile, IT is stuck in the middle trying to develop and engineer systems to enforce ever-changing data retention policies.
