Storagecraft Assigned Four Patents

Avoiding encryption in deduplication storage
Storagecraft Technology Corporation, Draper, UT, has been assigned a patent (9,626,518) developed by Gardner, Andrew Lynn, Oak City, UT, for a “avoiding encryption in a deduplication storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Avoiding encryption in a deduplication vault. In one example embodiment, a method may include analyzing an allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block not being stored, encrypting the allocated plain text block and analyzing the encrypted block to determine if the encrypted block is already stored in the deduplication storage, analyzing a second allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block already being stored, avoiding encryption of the second allocated plain text block by not encrypting the second allocated plain text block and instead associating the location of the second allocated plain text block in the source storage with the location of the duplicate block already stored.“

The patent application was filed on December 11, 2015 (14/966,406).

Avoiding compression of high-entropy data during creation
of backup of source storage
Storagecraft Technology Corporation, Draper, UT, has been assigned a patent (9,626,249) developed by Bushman, Nathan S., Pleasant Grove, UT, and Williams, Stephen, South Jordan, UT, for a “avoiding compression of high-entropy data during creation of a backup of a source storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Avoiding compression of high-entropy data during creation of a backup of a source storage. In one example embodiment, a method for avoiding compression of high-entropy data during creation of a backup of a source storage may include identifying a chunk with an original size in a file in a source storage, compressing, during creation of a backup of the source storage, the chunk to generate a compressed chunk with a compressed size, determining a compression ratio for the chunk by comparing the original size to the compressed size, determining whether the compression ratio is less than the compression threshold, and, in response to determining that the compression ratio is less than the compression threshold, automatically designating the file as a high-entropy file and automatically avoiding compression, during the creation of the backup, of chunks in a second similar file in the source storage.“

The patent application was filed on June 14, 2016 (15/182,303).

Filtering directory enumeration of directory to exclude files
with missing file content from image backup
Storagecraft Technology Corporation, Draper, UT, has been assigned a patent (9,619,335) developed by Bushman, Nathan S., Pleasant Grove, UT, and Williams, Stephen, South Jordan, UT, for a “filtering a directory enumeration of a directory to exclude files with missing file content from an image backup.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Filtering a directory enumeration of a directory to exclude files with missing file content from an image backup. In one example embodiment, a method for filtering a directory enumeration of a directory to exclude files with missing file content from an image backup may include exposing an image backup to directory enumeration commands, receiving a directory enumeration command corresponding to a directory of a file system of the exposed image backup, generating a filtered directory enumeration that excludes files where the files are listed in file system metadata, FSM, for the directory of the file system of the exposed image backup but where the file content of the files is missing from the exposed image backup, and returning the filtered directory enumeration.“

The patent application was filed on March 11, 2016 (15/068,162).

Migration of computer data
Storagecraft Technology Corporation, Draper, UT, has been assigned a patent (9,606,875) developed by Bushman, Nathan S., Pleasant Grove, UT, for a “migration of computer data.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Migration of computer information. In one example embodiment, a method for migration of computer data includes modifying a volume boot record of a destination volume to a first state in which at least a portion of the destination volume becomes inaccessible to a standard file system, writing one or more snapshots of a source volume to the inaccessible portion of the destination volume while the volume boot record is in the first state, and restoring the volume boot record to a second state in which the inaccessible portion of the destination volume becomes accessible to the standard file system.“

The patent application was filed on April 26, 2013 (13/872,001).
