Duplication

Duplication in computing refers to the process of replicating data, components, or systems to ensure redundancy and fault tolerance. This practice is essential for ensuring the integrity and availability of critical resources, particularly in high-stakes environments where system downtime can lead to significant losses. Duplication can occur at various levels, such as duplicating data across multiple disks in a RAID (Redundant Array of Independent Disks) configuration to prevent data loss in case of disk failure, or duplicating entire systems in a failover cluster to ensure seamless operation in case of hardware failure or software failure. While duplication adds system overhead in terms of storage space, processing power, and management complexity, it provides a crucial layer of protection against single points of failure and enhances overall system reliability and system availability.
