Data deduplication is important because it significantly reduces your storage space needs, saving you money and reducing how much bandwidth is wasted on transferring data to/from remote storage locations.
Why do we need data deduplication?
Data Deduplication helps storage administrators reduce costs that are associated with duplicated data. Large datasets often have a lot of duplication, which increases the costs of storing the data. For example: User file shares may have many copies of the same or similar files.
What are the benefits of deduplication?
