Lazy Exact Deduplication

open access: yesACM Transactions on Storage, 2016
Deduplication aims to reduce duplicate data in storage systems by removing redundant copies of data blocks, which are compared to one another using fingerprints. However, repeated on-disk fingerprint lookups lead to high disk traffic, which results in a bottleneck.

Learning to deduplicate

Proceedings of the 6th ACM/IEEE-CS joint conference on Digital libraries, 2006
Identifying record replicas in Digital Libraries and other types of digital repositories is fundamental to improve the quality of their content and services as well as to yield eventual sharing efforts. Several deduplication strategies are available, but most of them rely on manually chosen settings to combine evidence used to identify records as being

Metadedup: Deduplicating Metadata in Encrypted Deduplication via Indirection

2019 35th Symposium on Mass Storage Systems and Technologies (MSST), 2019
Encrypted deduplication combines encryption and deduplication in a seamless way to provide confidentiality guarantees for the physical data in deduplication storage, yet it incurs substantial metadata storage overhead due to the additional storage of keys.

Deduplication overlay network

2017 IEEE 16th International Symposium on Network Computing and Applications (NCA), 2017
Video content makes up more than half of the world's Internet traffic, and this figure is expected to grow rapidly. New techniques that remove traffic redundancy have been shown to significantly improve network performance since many concurrent streams deliver the same video. These techniques employ smart routers that recognize duplicated video streams

Deduplicating a places database

Proceedings of the 23rd international conference on World wide web, 2014
We consider the problem of resolving duplicates in a database of places, where a place is defined as any entity that has a name and a physical location. When other auxiliary attributes like phone and full address are not available, deduplication based solely on names and approximate location becomes an exceptionally challenging problem that requires ...

Demystifying data deduplication

Proceedings of the ACM/IFIP/USENIX Middleware '08 Conference Companion, 2008
Effectiveness and tradeoffs of deduplication technologies are not well understood -- vendors tout Deduplication as a "silver bullet" that can help any enterprise optimize its deployed storage capacity. This paper aims to provide a comprehensive taxonomy and experimental evaluation using real-world data.
