In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs.
Data deduplication technology can be used to very efficiently track and remove duplicate blocks of data inside a storage unit. There are a multitude of implementations, each with their separate advantages and disadvantages. Deduplication is most efficient at the shared storage layer, however, implementations in software and even databases exist.
It is a means to eliminate data duplication and to increase efficiency. SIS is frequently implemented in file systems, e-mail server software, data backup, and other storage-related computer software. Single-instance storage is a simple variant of data deduplication. While data deduplication may work at a segment or sub-block level, single ...
Software-defined storage typically includes a form of storage virtualization to separate the storage hardware from the software that manages it. [1] The software enabling a software-defined storage environment may also provide policy management for features such as data deduplication, replication, thin provisioning, snapshots and backup.
The term deduplication refers generally to eliminating duplicate or redundant information. Data deduplication , in computer storage, refers to the elimination of redundant data Record linkage , in databases, refers to the task of finding entries that refer to the same entity in two or more files

Capacity optimization is a general term for technologies used to improve storage use by shrinking stored data. Primary technologies used for capacity optimization are data deduplication and data compression. These are delivered as software or hardware, integrated with storage systems or delivered as standalone products.
Inline Volume Deduplication and Inline Volume Compression compress some of the data on the fly before it reaches the disks and designed to leave some of the data in the uncompressed form if it is considered by ONTAP to take a long time to process them on the fly, and to leverage other storage efficiency mechanisms for this uncompressed data later.
