Deduplication Algorithms

Deduplication algorithms identify and eliminate duplicate data by comparing data segments or chunks. They analyze files or data streams to find repeated patterns or blocks, storing only one copy of each unique segment. When duplicates are detected, only a reference to the original is kept, reducing storage space. This process can occur at the file level (entire files) or at a more granular level (small data blocks). Deduplication improves storage efficiency, reduces costs, and speeds up backup and restore operations, making it a vital technique in data management systems.
