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 application for such a system, and a key requirement for this is high write throughput. As Zhu et al. [3] state, throughput is a critical requirement for enterprise data protection since deduplication storage systems have been used to replace more traditional tape-based data protection systems (which typically have high streaming I/O throughput).
