We describe some of the design choices that were made during the development of a fast, scalable, inline, deduplication device. The system's design goals and how they were achieved are presented. This is the firs deduplication device that uses similarity matching. The paper provides the following original research contributions: we show how similarity(More)
Large backup and restore systems may have a petabyte or more data in their repository. Such systems are often compressed by means of deduplication techniques , that partition the input text into chunks and store recurring chunks only once. One of the approaches is to use hashing methods to store fingerprints for each data chunk, detecting identical chunks(More)
