Data de-duplication is most widely used for eliminating data redundancy. Instead of saving the files having the same data, it stores single file thus reduces the memory space usage. In many organizations, their database contains the data de-duplication. For example, the different user saves the same file having the same data at different, different spaces. De-duplication eliminates these all extra copies by saving just one copy of the data and replacing the other all copies with pointers that lead back to the original copy.
