Explain How De-duplication Works? |
|
Answer» In the context of disk storage, De-duplication refers to any algorithm that searches for DUPLICATE data objects (for example, blocks, chunks, files) and discards those DUPLICATES. When duplicate data is detected, it is not retained, but instead a “data pointer” is modified so that the storage system references an EXACT copy of the data object already stored on disk. This De-duplication feature WORKS well with DATASETS that have lots of duplicated date (for example, full backups).
