Which concept describes storing the same data in multiple locations to avoid losses in case of failure?

The concept of storing the same data in multiple locations to avoid losses in case of failure is known as data redundancy. This practice is integral to data management and disaster recovery strategies, as it ensures that if one instance of the data becomes compromised or inaccessible, copies remain available for recovery.

Data redundancy can provide significant benefits, particularly in environments where data availability and reliability are critical. For example, in cloud storage solutions and enterprise database systems, redundancy helps to protect against hardware failures, data corruption, and accidental deletions. The use of redundancy can be seen in various configurations, such as RAID (Redundant Array of Independent Disks) systems, multi-site replication, or backups stored in different geographical locations.

The other concepts mentioned do not relate directly to the idea of preventing data loss through duplication. Access control focuses on regulating who can view or use resources in a computing environment. Data archiving pertains to moving data that is no longer actively used to a separate storage for future reference, while integrity verification involves checking that data remains unchanged and uncorrupted. These concepts, while important in the broader context of data management and security, do not specifically address the redundancy of data storage.
