Abstract

See full text

Data is ingested from a source system. Ingesting the data includes determining corresponding chunk identifiers for a plurality of data chunks corresponding to the ingested data and for each of the plurality of data chunks, verifying whether the corresponding chunk identifier is included in a data structure tracking identifiers of data chunks that were already stored in a storage of a storage system before the data ingestion started and storing the data chunk in a storage based on the verification. After the ingesting is completed, deduplication of the ingested data chunks stored in the storage having a same chunk identifier is performed and the data structure is updated based on the deduplication.
