Abstract
Exemplary embodiments for increased in-line deduplication efficiency in a computing environment are provided. Embodiments include incrementing the size of data samples from fixed size data chunks for each nth iteration for reaching a full size of an object requested for in-line deduplication, calculating in nth iterations hash values on data samples from fixed size data chunks extracted from the object, and matching in a nth hash index table the calculated nth iteration hash values for the data samples from the fixed size data chunks with a corresponding hash value of existing objects in storage, wherein the nth hash index table is built for each nth iteration of the data samples belonging to the fixed data chunks.
