Maintenance-Efficient Erasure Coding for Distributed Archival Storage

Cuong Pham, Feng Zhang, Duc A. Tran
2011 2011 Proceedings of 20th International Conference on Computer Communications and Networks (ICCCN)  
Erasure coding, widely used in many distributed storage systems for its high reliability, is efficient for access but not so efficient for maintenance.  ...  In many cases, such as in archival storage where data access is infrequent, the workload due to maintaining a system is dominant and much heavier than that to answering retrieval queries.  ...  Matt Welsh for making CitySense available for the implementation discussed in this paper.  ...
