| 20080275923 | METHOD FOR THE EXPUNGEMENT OF BACKUP VERSIONS OF FILES ON SERVER TARGETS THAT ARE CONFIGURED TO BE UPDATED SEQUENTIALLY - The present invention relates to a method for expunging backup versions of files that are stored at target servers, wherein the target servers are configured to be sequentially updated. The method comprises uploading a predetermined base file to a backup target server from a backup client, uploading a plurality of delta files to the backup target server from the backup client, and determining the chronological order in which the delta riles were uploaded to the backup target server. The method further comprises determining a set of chronologically oldest delta files, downloading the set of chronologically oldest delta files to the backup client, and merging the downloaded chronologically oldest delta files into a single delta file. Yet further, the method comprises uploading the merged delta file to the target server, and deleting the determined set of chronologically oldest delta files at the target server. | 11-06-2008 |
| 20110016095 | Integrated Approach for Deduplicating Data in a Distributed Environment that Involves a Source and a Target - One aspect of the present invention includes a configuration of a storage management system that enables the performance of deduplication activities at both the client (source) and at the server (target) locations. The location of deduplication operations can then be optimized based on system conditions or predefined policies. In one embodiment, seamless switching of deduplication activities between the client and the server is enabled by utilizing uniform deduplication process algorithms and accessing the same deduplication index (containing information on the hashed data chunks). Additionally, any data transformations on the chunks are performed subsequent to identification of the data chunks. Accordingly, with use of this storage configuration, the storage system can find and utilize matching chunks generated with either client- or server-side deduplication. | 01-20-2011 |
| 20110040732 | APPROACH FOR SECURING DISTRIBUTED DEDUPLICATION SOFTWARE - The various embodiments of the present invention include techniques for securing the use of data deduplication activities occurring in a source-deduplicating storage management system. These techniques are intended to prevent fake data backup, target data contamination, and data spoofing attacks initiated by a source. In one embodiment, one technique includes limiting chunk querying to authorized users. Another technique provides detection of attacks and unauthorized access to keys within the target system. Additional techniques include the combination of validating the existence of data from the source by validating the data chunk, validating a data sample of the data chunk, or validating a hash value of the data chunk. A further embodiment involves the use of policies to provide authorization levels for chunk sharing and linking within the target. These techniques separately and in combination provide a comprehensive strategy to avoid unauthorized access to data within the target storage system. | 02-17-2011 |

| 20080281881 | RECONCILIATION OF LOCAL AND REMOTE BACKUP DATA - Provided are a system, an article of manufacture, and a computer program product, wherein a first set of backup data is stored in a first computational device and a second set of backup data is stored in a second computational device. Metadata corresponding to the first set of backup data is maintained in the second computational device. The first set of backup data is reconciled with the second set of backup data based on the metadata. | 11-13-2008 |
| 20090063430 | ARTICLE OF MANUFACTURE AND SYSTEM FOR MERGING METADATA ON FILES IN A BACKUP STORAGE - Provided are a system and article of manufacture for merging metadata on files in a backup storage. A query is received for information on files from a file system for a client node. A determination is made of metadata for files in a backup storage for the client node stored external to backup sets. At least one backup set in the backup storage for the client node is processed to determine metadata for files included in at least one backup set. The determined metadata for files in the backup storage and for files included in at least one backup set is merged to form merged metadata. The query is executed against the merged metadata to determine files whose metadata satisfies the query. Results including information from the merged metadata on the determined files are returned. | 03-05-2009 |
| 20090119354 | METHOD, SYSTEM, AND PROGRAM IMPLEMENTING RETENTION POLICIES TO ARCHIVE RECORDS - Provided are a method, system, and program for receiving a request to remove a record. A determination is made as to whether a state associated with the record includes at least one hold state and whether the state associated with the record includes at least a retention period that has not expired. The request to remove the record is denied in response to determining that the state associated with the record includes at least one of at least one hold state and one retention period that has not expired. | 05-07-2009 |
| 20100263030 | METHOD FOR ESTABLISHING AN AGENCY RELATIONSHIP TO PERFORM DELEGATED COMPUTING TASKS - A method is disclosed for establishing an agency relationship to perform delegated computing tasks. The method provides for initiation of the agency relationship, establishment of credentials to perform a delegated computing task, and performance of the delegated computing task. Benefits of establishing an agency relationship in a computing environment include improved security, efficiency, and reliability in performing delegated computing tasks. | 10-14-2010 |
| 20100306178 | SEPARATING FILE DATA STREAMS TO ENHANCE PROGRESSIVE INCREMENTAL PROCESSING - 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. | 12-02-2010 |
