Byte-level deduplication: This form of deduplication is sourced and deleted from the byte level.Block-level deduplication: Files are categorized into blocks and compared by fixed or indefinite lengths or by hash values of the stored block.If no similar file can be found, it is stored and updated in the index. It is used for storing files according to the index and is compared to the existing stored file. File-level deduplication: This type of deduplication is also referred to as single-instance storage (SIS).Adaptive data deduplication: Online deduplication is used when an environment has low-performance requirements and post-processing deduplication is adopted for high-performance requirements.Post-processing deduplication: Just like it sounds, this method of deduplication starts after data is already written to a disk. Inline deduplication: Removing duplicate data before it is written to a disk.Target-side deduplication: In contrast to source-side deduplication, this type of deduplication transfers the data to a backup device before deleting the duplicate data when storing.Source-side deduplication: This is the process of deleting duplicate data and thereafter transferring that data to a backup device.There are several different types of deduplication, including:
