Data redundancy refers to the practice of storing copies of data in multiple locations or formats to enhance reliability and availability. This strategy ensures that if one data source becomes unavailable—due to hardware failure, data corruption, or natural disasters—there are additional copies that can be relied upon. This redundancy is a fundamental principle in data management, especially in cloud environments and disaster recovery planning, where ensuring continuous access to data is critical.

By employing data redundancy, organizations can improve data integrity and reduce the risk of data loss. For example, if a business keeps backups of its critical data across different geographical locations, it can quickly recover from unforeseen events without significant downtime.

Other options, while they represent different data management strategies or philosophies, do not align with the principle of data redundancy. Using a single location for all data compromises reliability since it creates a single point of failure. Compressing data is focused on saving storage space and improving access speed, rather than ensuring data availability. Finally, limiting data storage to essential information contradicts the concept of redundancy, as it means not keeping extra copies of data, which is essential for prevention against data loss.
