Storage systems contain redundant copies of data such as identical files or within sub-file regions. Using deduplication technology, we can take advantage of this re-dundancy and reduce the space needed to store files in the file system. Scalable, highly reliable distributed systems supporting data deduplication have recently become popular for storing backup and archival data. There is potential for this technology to be adapted to primary storage. This dissertation is focused on solving the storage problem, designing and de- veloping HD2FS, improving data storage capacity and efficiency in distributed file systems.
