Backing Up & Archiving (1.3.h)

Backing up is making regular copies of data in order to protect it from disaster, such as fire, theft, or accidental deletion. If something were to happen to the original copy of the data, the data could be restored from the backup.

Archiving is the infrequent transfer and removal of data from a system. For example, removing the details of students that have left from a school computer system. The data must be kept in archives in case the student later asks for a reference, however it shouldn't be taking up space on the main computer system.
