Threats of Human Error in a High-Performance Storage System: Problem   Statement and Case Study
  System administration is a difficult, often tedious, job requiring many skilled laborers. The data that is protected by system administrators is often valued at or above the value of the institution maintaining that data. A number of ethnographic studies have confirmed the skill of these operators, and the difficulty of providing adequate tools. In an effort to minimize the maintenance costs, an increasing portion of system administration is subject to automation - particularly simple, routine tasks such as data backup. While such tools reduce the risk of errors from carelessness, the same tools may result in reduced skill and system familiarity in experienced workers. Care should be taken to ensure that operators maintain system awareness without placing the operator in a passive, monitoring role.
