The automatic elimination of duplicate data in a storage system, commonly known as
deduplication, is increasingly accepted as an effective technique to reduce storage costs …

Windows Azure Storage (WAS) is a cloud storage system that provides customers the ability
to store seemingly limitless amounts of data for any duration of time. WAS customers have …

We collected file system content data from 857 desktop computers at Microsoft over a span
of 4 weeks. We analyzed the data to determine the relative efficacy of data deduplication …

Traditionally, file systems were implemented as part of OS kernels. However, as complexity

Abstract Although Flash Memory based Solid State Drive (SSD) exhibits high performance
and low power consumption, a critical concern is its limited lifespan along with the …

We design flexible schemes to explore the tradeoffs between storage space and access
efficiency in reliable data storage systems. Aiming at this goal, two new classes of erasure …

Data-intensive clusters and object stores are increasingly relying on in-memory object
caching to meet the I/O performance demands. These systems routinely face the challenges …

Storage deduplication has received recent interest in the research community. In scenarios
where the backup process has to complete within short time windows, inline deduplication …

A cloud storage system, consisting of a collection of storage servers, provides long-term
storage services over the Internet. Storing data in a third party's cloud system causes serious …

Modern deduplication has become quite effective at eliminating duplicates in data, thus
multiplying the effective capacity of disk-based backup systems, and enabling them as …
