Description: What does Backup mean? Backup refers to the process of making copies of data or data files to use in the event the original data or data files are lost or destroyed. Secondarily, a backup may refer to making copies for historical purposes, such as for longitudinal studies, statistics or for historical records or to meet the requirements of a data retention policy. Many applications, especially in a Windows environment, produce backup files using the .BAK file extension.
