Abstract
A data deduplication method providing direct look up and storage in an instance repository (IR). The method includes receiving a data object and processing the data object to generate a fingerprint that includes a location component, which defines a file location within the IR such as by first using a hash function to create a hash for the data object and parsing the hash value into sub-strings defining sub-directories of the IR. The method includes determining whether the data object is a duplicate by verifying the presence of a file in the IR at the file location. Determining if the data is unique involves performing a system call on the IR providing the location component as the file path. The method includes, when a file is not in the IR, updating the IR to store the data object as a file at the file location defined by the location component.
