Patent number: 11385966Abstract: A copy procedure detects qualified data objects in a body of source data, and copies the source data to a target storage unit except for unqualified data objects, which are replaced with a prescribed bit pattern. Following completion of the backup, a record is prepared indicating that all data objects exist in the specified target storage, regardless of whether each data object was replaced with a predetermined bit pattern rather than being physically written to the specified target storage. This process may, be repeated in order to perform data reclamation, effectively removing user files no longer qualifying for backup.Type: GrantFiled: May 21, 2010Date of Patent: July 12, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventor: David Maxwell Cannon

Patent number: 8738588Abstract: Sequential media reclamation is usually performed after portions of a sequential access volume's data are no longer needed and the unused portion of the volume exceeds a threshold. Improved sequential media reclamation is provided by using a sequential access disk volume (for example, a volume of a virtual tape library (VTL)) embodied as a sparse file. Reclamation of objects stored in the volume is accomplished by nulling out regions of the sparse file that contain the objects that are no longer needed. A replication method is also provided in which information about the objects stored in the sparse file (such as offset and length) is used during replication to enable the correct portions of a target volume (embodied as a sparse file) to be nulled out to match a source volume (also embodied as a sparse file).Type: GrantFiled: March 26, 2007Date of Patent: May 27, 2014Assignee: International Business Machines CorporationInventors: David Maxwell Cannon, Michael Allen Kaczmarski

Patent number: 8615534Abstract: Provided are a computer program product, method, and system for migration of metadata and storage management of data in a first storage environment to a second storage environment. A migration request is processed to migrate metadata and storage management of data in a first storage environment to a second storage environment. First metadata for the first storage environment is copied to the second storage environment to incorporate with second metadata. The first metadata incorporated into the second metadata is modified to indicate first server information used by a second server to communicate with a first server to access the migrated data from the first storage media. The migration request is completed in response to incorporating the first metadata into the second metadata, wherein the first data objects remain in the first storage media after completing the migration request.Type: GrantFiled: June 19, 2012Date of Patent: December 24, 2013Assignee: International Business Machines CorporationInventors: David Maxwell Cannon, Robert Gerard LaBrie

Patent number: 8326896Abstract: Provided is a method, system and program for storing data for later retrieval and for transfer within a storage hierarchy. A data storage subsystem stores both individual user files and also managed files, each managed file comprising an aggregation of multiple user files. After receiving user files from a client station, the subsystem stores user files in a retrieval storage pool to facilitate file retrieval. Criteria are subsequently applied to the user files stored in the retrieval storage pool to delete low or lower priority files from the retrieval storage pool. In addition, user files are aggregated in managed files for transfer to another location within the storage hierarchy.Type: GrantFiled: July 21, 2008Date of Patent: December 4, 2012Assignee: International Business Machines CorporationInventors: David Maxwell Cannon, Donald Paul Warren, Jr., Howard Newton Martin

Patent number: 8185496Abstract: Systems, methods, and computer products for separating file data streams for improved progressive incremental processing are provided. The method comprises identifying data in a file, prior to transmission of the data in a data stream to a second system, such that the second system can distinguish first data from second data in the file. The method further comprises processing the first and second data to determine whether the first or second data has changed, and transmitting the first data to the second system in response to determining the first data has changed, so that the first data is stored in a data storage medium in association with third and fourth data previously stored without replacing the third data and fourth data, wherein the third and fourth data comprise older versions of the first and second data, respectively.Type: GrantFiled: August 18, 2010Date of Patent: May 22, 2012Assignee: International Business Machines CorporationInventors: Matthew Joseph Anglin, David Maxwell Cannon, Barry Fruchtman, Avishai Haim Hochberg, James Patrick Smith
