VIII. Data Security and Recovery

Students need to know that data security and recovery procedures exist, but most of all that a useful procedure for every user is the practice of making backup copies of all significant data. Security systems for those backup copies are often forgotten. Basic handling and care of floppy diskettes is a beginning point for the novice user.

Understanding data storage and recovery techniques using commercial software utilities is fundamental for regular users of personal computers. Prevent lost data by training users to use equipment properly and to identify the exact sequence of events that happened before something went wrong. One should emphasize the importance of a bound log book. This is often a great aid to those who must “undo” the problem. For more sensitive data, consider encryption techniques.
