Storage Systems Research Center

Data deduplication is an essential and critical component of backup systems. Essential, because it reduces storage space requirements, and critical, because the performance of the entire backup operation depends on its throughput. Traditional backup workloads consist of large data streams with high locality, which existing deduplication techniques require to provide reasonable throughput.

We have developed Extreme Binning, a scalable deduplication technique for non-traditional backup workloads that are made up of individual files with no locality among consecutive files in a given window of time. Due to lack of locality, existing techniques perform poorly on these workloads. Extreme Binning exploits file similarity, and makes only one disk access for chunk lookup per file, which gives reasonable throughput. Multi-node backup systems built with Extreme Binning scale gracefully with the amount of input data; more backup nodes can be added to boost throughput. Each file is allocated using a stateless routing algorithm to only one node, allowing for maximum parallelization, and each backup node is autonomous with no dependency across nodes, making data management tasks robust with low overhead.

The Storage Systems Research Center is part of the Jack Baskin School of Engineering at the University of California, Santa Cruz. Composed of faculty from the Computer Science, Computer Engineering, and Electrical Engineering departments, our research focuses on many aspects of file and storage systems. We have active projects in archival storage, scalable distributed indexing and non-hierarchical file systems, large-scale distributed storage systems, file systems for next-generation storage devices, and data deduplication. We also have particular focus in cross-cutting issues such as security and reliability in file and storage systems. You're encouraged to browse a full list of our projects and explore the research that the SSRC has done since 2001.

Prospective graduate students

Applications for graduate school at UC Santa Cruz are due at the end of each calendar year. We have lots of information available online for prospective graduate students.
