Abstract
Exemplary system, and computer program product embodiments for data deduplication using short term history in a computing environment are provided. In one embodiment, by way of example only, a hash value is calculated on data chunks for a read operation. The calculated hash value is stored in a storage media. The calculated hash value is looked up in the storage media to verify if a current write operation was previously written and/or read. Additional system and computer program product embodiments are disclosed and provide related advantages.
