A data deduplication scheme is designed in the proposed private cloud storage system to reduce cost and increase the storage efficiency.
Although the schemes solve the problem of communication overhead, they prove ineffective for inter-node data deduplication system.
HAMMER supports configurable file system history, snapshots, checksumming, data deduplication and other features typical for file systems of its kind.
Large-scale cluster deduplication schemes face challenge of information-island (only server-level deduplication is possible due to the communication overhead) where data routing is the key issue.
Waving $2.4 billion in cash, EMC finally beat out NetApp, its archrival in the storage business, for the right to acquire Data Domain and its data deduplication technology.
Data Domain is a market leader in data deduplication, which helps get rid of redundant data that consumes space in computers, one of the fastest-growing segments in storage.
The stateful data routing schemes, as compared to stateless approaches, have higher overhead with low imbalance in the data which minimizes the utility of data deduplication systems.
Therefore, data deduplication is widely used for accelerating VM storage data migration.
The authors in [13] characterized the deduplication schemes in terms of energy impact and performance overhead.
One of the solutions to reduce the amount of data transfer is data deduplication.
