Abstract:
A storage system includes a storage operating system configured to provide two-step data deduplication in which, during a data storage operation and prior to committing data to a storage medium of the storage system, context-aware data deduplication is performed on the data to obtain context-aware deduplicated data, and, subsequent to committing the context-aware deduplicated data to the storage medium, a context-independent data deduplication operation is performed on the context-aware deduplicated data to obtain context-independent deduplicated context-aware deduplicated data, for commitment to the storage medium.
