Which term refers to maintaining data availability by replicating data across multiple storage locations, including cloud storage?

• A. Data Redundancy
• B. Data Security
• C. Data Integrity
• D. Data Confidentiality

Answer: (A)

Data redundancy is about ensuring data stays accessible by duplicating copies across multiple storage locations, including cloud storage. This replication creates fault tolerance: if one site or storage device fails, the system can continue to operate using the other copies, keeping data available and supporting recovery after outages or disasters. While this focuses on keeping data accessible, other terms address different security goals—data security protects against unauthorized access, data integrity ensures the data remains accurate and unaltered, and data confidentiality limits who can view the data. So, duplicating data across locations is the mechanism that maintains availability through redundancy, including cloud environments.
