Block-level Deduplication

Block-level deduplication is a data storage technique that identifies and removes duplicate pieces of data, called blocks, within a storage system. Instead of saving multiple copies of identical data, it stores only one copy and references it whenever needed. This process reduces the overall amount of storage space used and improves efficiency. For example, if many files contain similar content, block-level deduplication eliminates redundant data at a granular level, saving space without affecting the files' integrity or accessibility. It's widely used in backup systems and storage networks to optimize capacity and reduce costs.
