Actifio Assigned Patent

Actifio, Inc., Waltham, MA, has been assigned a patent (9,880,756) developed by Mutalik, Madhav, Southborough, MA, Abercrombie, Philip J., Belmont, MA, and Provenzano, Christopher A., Somerville, MA, for a “successive data fingerprinting for copy accuracy assurance.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems and methods are disclosed for checking the data integrity of a data object copied between storage pools in a storage system by comparing data fingerprints of data objects, by scheduling a series of successive copy operations over time for copying a data object from a source data store to a target data store, generating a partial fingerprint of the data object at the source data store using a data fingerprinting operation that creates a fingerprint from a subset of data of the data object, sending the partial fingerprint of the data object to the target data store, sending any new data contents for the data object to the target data store, and creating a partial fingerprint of the data object at the target data store and comparing it to the partial fingerprint sent to the target data store to determine if they differ.”

The patent application was filed on March 10, 2015 (14/643,193).
