Storagecraft Assigned Two Patents

Hybrid image backup of source storage
Storagecraft Technology Corporation, Draper, UT, has been assigned a patent (9,886,351) developed by Bushman, Nathan S., Barnes, Scott, Pleasant Grove, UT, and Shreeve, Thomas Russell, Draper, UT, for an “hybrid image backup of a source storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Creating hybrid image backups of a source storage. In one example embodiment, a method for creating one or more hybrid image backups of a source storage may include seeding a deduplication system by storing, in the deduplication system, blocks included in one or more files of one or more operating systems, blocks included in one or more files of one or more software applications, or both, and by storing a hash of each of the seeded blocks in a hash data structure, copying the hash data structure into a solid state drive, SSD, placing the SSD in a read-only state, comparing hashes of allocated blocks stored in the source storage at a first point in time to hashes in the hash data structure to determine whether each of the allocated blocks is in a first set of blocks that are stored in the deduplication system or in a second set of blocks that are not stored in the deduplication system, associating locations of the blocks in the first set of blocks stored in the source storage with locations of the corresponding blocks stored in the deduplication system, storing the blocks in the second set of blocks in an image backup separate from the deduplication system, associating locations of the blocks in the second set of blocks stored in the source storage with locations of the corresponding blocks stored in the image backup, and defining a full hybrid image backup of the source storage at the first point in time as a combination of the first set of blocks stored in the deduplication system and the second set of blocks stored in the image backup.”

The patent application was filed on October 3, 2016 (15/284,310).

Live updating of changed block tracking driver
Storagecraft Technology Corporation, Draper, UT, has been assigned a patent (9,886,265) developed by Coffing, Charles, Riverton, UT, and Meyer, Kai, Lehi, UT, for a “live updating of a changed block tracking driver.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Live updating of a changed block tracking, (CBT) driver. In one example embodiment, a method for live updating of a CBT driver may include loading a CBT driver into a running operating system and then performing various acts without rebooting the running operating system. These acts may include tracking, using the CBT driver, writes to blocks of a source storage, loading an updated CBT driver into the running operating system with the updated CBT driver having a different name than the CBT driver, handing over the tracking of writes to blocks of the source storage from the CBT driver to the updated CBT driver, and tracking, using the updated CBT driver, writes to blocks of the source storage.”

The patent application was filed on April 20, 2017 (15/492,974).
