Dedupe-Centric Storage for General Applications
Dedupe-centric storage is engineered from the start to address these challenges. This paper gives historical perspective and a technological context to this revolution in storage management.DEDUPLICATION STORAGE 2.

Data deduplication - Wikipedia
In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. A related and somewhat synonymous term is single-instance (data) storage. This technique is used to improve storage utilization and can also be applied to network data transfers to reduce the number of bytes that must be sent.
The benefits of deduplication and where you should dedupe ...
Dedupe is referred to as being in-line (also called in-band) when data is analyzed for duplicates while it is being written to the storage media. In contrast, post-process (or out-of-band) dedupe takes place after the data has been written to disk.
Hugo Patterson, Chief Architect, Data Domain Deduplication ...
Deduplication should be effective and scalable so that it can find a small segment of matching data no matter where it is stored in a large system . Deduplication also needs to be efficient or the memory and computing overhead of finding duplicates in a large system could negate any benefit . finally, deduplication needs to be simple and
VM-Centric Snapshot Deduplication for Cloud Data Backup
sideration includes VM-centric file system block management for the increased VM snapshot availability. This paper describes an evaluation of this VM-centric scheme to assess its deduplication efficiency, resource usage, and fault tolerance. I. INTRODUCTION Commercial “Infrastructure as a Service” clouds (i.e. public
Event Sourcing Projections patterns: Deduplication ...
Because of that it is usually necessary to implement deduplication in order to achieve (perceived) idempotency. Although some of the message queues / streaming platforms claim that they can deliver exactly once semantics the answer to the deduplication problem is nuanced and we can't get away without solving it. Naturally idempotent projections

String Deduplication - A new feature in Java 8 Update 20 ...
String Deduplication – A new feature in Java 8 Update 20. In above case all strings could be deduplicated, removing 4.5MB of data from memory. The Table section gives statistics about the internal tracking table, and the Queue one lists how many requests for deduplication have been dropped due to load, which is one part of the overhead reduction mechanism.
