It's likely you have landed here because deduplication, also referred to as dedup, has become a hot topic for you or your organization. It's a fairly straightforward concept: instead of storing multiple copies of the same data, why not use pointers to unique copies? You may have run into similiar technologies such as single information store in Microsoft® Exchange. This page is to introduce you to the concept, and then show you a few key places to go for more information. Need a specific question answered? Checkout the dedup chat transcript linked below. From the dell.com/dedup site: Deduplication is a storage-optimization technology that reduces the data footprint by eliminating multiple copies of redundant data and storing only unique data. Copies of the redundant data are replaced by references to the original data, sometimes called “pointers.” Deduplication of redundant data can occur at the file, sub-file, or block level. At the sub-file and block levels, data commonly is divided into smaller segments which can be more easily analyzed for possible redundancies, as compared to using file level data, and more efficiently stored.
