Distributed Data Storage with Data Versioning
Lukáš Hejtmánek · 2006
In this paper, we have demonstrated the concept of a distributed file system that supports file versioning, file sharing, and endless files based on sliding window approach. It uses a distributed storage substrate that provides immutable block allocations, and a metadata manager, that maps files to data blocks using metadata. While file versioning and read-write sharing are often understood as contradictory, we demonstrate the approach that allows both properties to coexist. We have described the application-level prototype implementation, that we use for verifying this concept.
