Depending on what server(s) PHB is talking about, the request is not as unreasonable as it seems. At one company I know of, users would routinely back up their entire C: drive to the home drive stored on the server. That means that anywhere between 1GB to 4GB of data is being stored on the server that not only is duplicated on CDs, but cannot be used to restore the programs because the programs must be installed, not just copied back to the local drive.
Of course, that paled in comparison to the storage space used by PST files that were full of email requests to enlarge body parts, fix credit, and join !$%* sites.
Management in my experience tend to think either everything is necessary, or everything is junk. IT, on the other hand, invariably think the opposite. Mordak couldn't survive without this state affairs. An equilibrium, if you will, with Dilbertesques caught in the middle.
Reminds me of the memo that used to be sent out by management at least once a month to all employees:
"The servers are running low on space. Please delete all unnecessary data from your personal directories."
Which is like asking a pack rat to get rid of things they don't think is important to them...vis. nothing.
Or, on a more professinal level, maintaining 16 test databases, including one back-up, when only three are necessary, and wondering why the system runs so slowly during peak processing times.
