Patent number: 8640136Abstract: An object management system (10) comprises a storage device (12); a first computer system (12) configured to store a first object, and a copy of the first object on the storage device; and a second computer system. The first computer system is configured to create a first data object including information about the stored copy of the first object, and the second computer system is configured to read the information about the stored copy of the first object from the first data object, and retrieve the stored copy of the first object from the storage device. The first object may be partitioned by the first computer system and stored as partitions on the storage device, and the first data object would contain information about the partitions. The second computer system would be configured to read information about the partitions from the first data object, select partitions from the storage device.Type: GrantFiled: November 5, 2008Date of Patent: January 28, 2014Assignee: EMC CorporationInventors: Mark Saake, Richard Ruef, Kurt Everson

Patent number: 8484172Abstract: A computer system configured to store a plurality of files, and a data file, which includes inode and migration or purge information associated with the files. The computer system searches the data file to identify files that are candidates for migration or purge. A plurality of pathnames associated with the files is stored in the data file or a separate data file, and the computer system obtains the pathnames of candidate files from the data file (or separate data file). When candidate files are identified, their inodes are used to look up their pathnames in the plurality of pathnames. The data file may include information about whether a file has been modified and its time of last access. To determine whether a file is a candidate for migration, its entry in the data file is checked to determine whether it has been modified. If it has, it is identified as a migration candidate.Type: GrantFiled: September 26, 2002Date of Patent: July 9, 2013Assignee: EMC CorporationInventors: Mark Saake, Richard Ruef, Kurt Everson

Patent number: 8442957Abstract: An object management system comprises a computer system configured to store an object (72), which may be a file. The computer system is configured to divide the object (72) into partitions (70), select partitions, and provide the selected partitions to a storage device (14) for storage. The partitions are selected by determining which partitions need to be migrated device, based on whether the partitions have been modified. The system determines this by examining a data object associated with the object. The computer system may be configured to retrieve a selected partition from the storage device.Type: GrantFiled: September 20, 2002Date of Patent: May 14, 2013Assignee: EMC CorporationInventors: Mark Saake, Richard Ruef, Kurt Everson
