Jumbo Store: Providing Efficient Incremental Upload and Versioning for a Utility Rendering Service
Overview The paper has developed a new storage system called the Jumbo Store (JS) based on encoding directory tree snapshots as graphs called HDAGs whose nodes are small variable-length chunks of data and whose edges are hash pointers. The paper stores or transmits each node only once and encodes using landmark-based chunking plus some new tricks. This leads to very efficient incremental upload and storage of successive snapshots: the paper reports compression factors over 16x for real data; a comparison shows that the incremental upload sends only 1/5 as much data as Rsync.
