Data Deduplication

Data deduplication is a form of compression that eliminates redundant data on a subfile level, improving storage utilization. In this process, only one copy of the data is stored; all the redundant data will be eliminated, leaving only a pointer to the previous copy of the data. Deduplication can significantly reduce the required disk space, since only the unique data is stored.
