File Deduplication using Logical Partition of Storage System

Project Description Userspace Deduplication File System using FUSE

As we will cover later in the course, disk-based deduplication storage [1,3] has emerged as a dominant form of cost-efficient storage for data protection. In summary, as data is written to (or ingested by) such storage systems, deduplication mechanisms remove redundant segments of the data to compress the data into a highly compacted form. Data protection (i.e. disk backup) is the canonical app...

Achieving Storage Efficiency through Emc Vnx File Deduplication and Compression

This white paper describes VNX File Deduplication and Compression, a feature of EMC VNX that increases the efficiency of storing network-attached storage (NAS) data. This paper outlines the motivation for increased storage efficiency, how VNX File Deduplication and Compression works, the principles and technical architecture behind it, and how it interacts with other VNX features and functions....

Efficient and Secure File Deduplication in Cloud Storage

Outsourcing to a cloud storage brings forth new challenges for the efficient utilization of computing resources as well as simultaneously maintaining privacy and security for the outsourced data. Data deduplication refers to a technique that eliminates redundant data on the storage and the network, and is considered to be one of the most-promising technologies that offers efficient resource uti...

Dynamic Deduplication Decision in a Hadoop Distributed File System

Decentralized Deduplication in SAN Cluster File Systems

File systems hosting virtual machines typically contain many duplicated blocks of data resulting in wasted storage space and increased storage array cache footprint. Deduplication addresses these problems by storing a single instance of each unique data block and sharing it between all original sources of that data. While deduplication is well understood for file systems with a centralized comp...
