Abstract
A receiver-side deduplication architecture for data storage systems, for example remote data storage systems that use block-based data storage and that provide the data storage to client(s) via a network. The architecture may provide network deduplication by reducing bandwidth usage on communications channel(s) between the client(s) and the data storage systems. The architecture may leverage block storage technology of a data store provided to clients by a data store provider and caching technology to implement a deduplication data dictionary. The deduplication data dictionary includes deduplication data blocks stored in the data store and a mapping tier that leverages caching technology to store and maintain a store of key/value pairs that map data block fingerprints to deduplication data blocks in the data store.
