StorageCraft Assigned Three Patents

Consolidating encrypted image backups without decryption
StorageCraft Technology Corporation, Draper, UT, has been assigned a patent (9,794,061) developed by Bushman, Nathan S., Pleasant Grove, UT, for a “consolidating encrypted image backups without decryption.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Consolidating encrypted image backups without decryption. In one example embodiment, a method for consolidating encrypted image backups without decryption may include individually encrypting, using a single encryption function, each block in a first set of blocks in a source storage, storing the first set of encrypted blocks in a first encrypted image backup, individually encrypting, using the single encryption function, each block in a second set of blocks in the source storage, storing the second set of encrypted blocks in a second encrypted image backup, and creating a consolidated encrypted image backup that includes a single encrypted block for each of multiple unique block positions represented by the first and second sets of encrypted blocks without decrypting any of the encrypted blocks.”

The patent application was filed on June 14, 2016 (15/182,293).

Head start population of image backup
StorageCraft Technology Corporation, Draper, UT, has been assigned a patent (9,740,569) developed by Bushman, Nathan S., Pleasant Grove, UT, for a “head start population of an image backup.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Head start population of an image backup. In one example embodiment, a method for head start population of an image backup may include tracking blocks that are modified in a source storage between a first point in time and a second point in time, head start copying a first portion of the modified blocks into the image backup prior to the second point in time and ceasing the tracking of the first portion of the modified blocks as being modified, activating a snapshot on the source storage at the second point in time where the snapshot represents a state of the source storage at the second point in time, and copying, subsequent to the second point in time, from the snapshot and into the image backup, a second portion of the modified blocks that were not yet copied into the image backup by the second point in time.”

The patent application was filed on December 11, 2015 (14/966,433).

Tracking content blocks in source storage for inclusion
in image backup of source storage
StorageCraft Technology Corporation, Draper, UT, has been assigned a patent (9,727,264) developed by Bushman, Nathan S., Pleasant Grove, UT, for a “tracking content blocks in a source storage for inclusion in an image backup of the source storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Tracking content blocks in a source storage for inclusion in an image backup of the source storage. In one example embodiment, a method for tracking content blocks in a source storage for inclusion in an image backup of the source storage may include identifying files in a source storage for inclusion in image backups of the source storage, tracking, in an inclusion map and prior to a first snapshot time, locations in the source storage of content blocks of the identified files, tracking, in the inclusion map and prior to the first snapshot time, modifications to the locations in the source storage of the content blocks, taking a snapshot of the source storage at the first snapshot time, and backing up, subsequent to the first snapshot time, the content blocks tracked in the inclusion map from the snapshot into a full image backup.”

The patent application was filed on June 14, 2016 (15/182,282).
