One of the "fallback" procedures of a computing center is the "grandfather?parent-child" file arrangement.

Question

Quizplus · Accepted Answer

The "grandfather-parent-child" file arrangement is a commonly used backup strategy in computing centers where data is organized into three levels: the grandfather level (the oldest backup), the parent level (a moderately recent backup), and the child level (the most recent backup). In case of a data loss, the computing center can recover the lost data from the most recent backup (child level), or from the parent or grandfather level, depending on the extent of the data loss. This strategy ensures that multiple backups are available to restore data in case of a disaster.
