| 20080243956 | MANAGEMENT DEVICE AND METHOD FOR STORAGE DEVICE EXECUTING CDP-BASED RECOVERY - A management device of a storage device that executes CDP-based recovery comprises: a data protection term acquisition section that acquires a data protection term which is a term in which recovery of a data volume is ensured from a predetermined duration for which a predetermined time is a reference point; and a control section that executes control using the data protection term. | 10-02-2008 |
| 20080320219 | COMPUTER AND METHOD FOR CONFIGURING DATA BACKUP ENVIRONMENT USED BY PLURALITY OF ASSOCIATIVELY OPERATED APPLICATIONS - The present invention stores application management information indicating respective applications constituting a federated application environment, which is a group constituted by a plurality of associatively operated applications. By referencing this application management information, a plurality of applications constituting this federated application environment are specified. A plurality of first logical volumes allocated to the specified plurality of applications, and a plurality of second logical volumes constituting the backup targets for data stored in the plurality of first logical volumes, are assigned to the same volume group. | 12-25-2008 |
| 20090013012 | JOURNAL MANAGEMENT METHOD IN CDP REMOTE CONFIGURATION - A first storage system specifies a journal to be transferred in accordance with a time period for retaining write data in update (write) units of data in a second storage system, and transfers this journal to the second storage system. Data for which the retention period has expired is transferred by selecting write data by address. | 01-08-2009 |
| 20090070390 | RECOVERY METHOD USING CDP - First information representing a plurality of snapshot acquisition time points of the data storage device, journal management data which are second information including the time point at which data are written to the data storage device and the size of the journal for writing the data, and third information representing a plurality of recovery points are acquired. The total transfer data size of one or more data to be transferred in order to recover the data group of the data storage device at the recovery point is calculated for each recovery point on the basis of the first information, journal management data, and third information. A display screen that visualizes the correspondence relationship between the respective recovery points and respective recovery load information representing a recovery load that is expressed on the basis of the total transfer data size calculated for the respective recovery points is displayed. | 03-12-2009 |
| 20090077336 | STORAGE SYSTEM AND STORAGE SYSTEM DATA MIGRATION METHOD - This storage system modifies the migration plan in accordance with the state of the migration destination when a plurality of volumes are migrated all at once. Migration-source volumes are migrated collectively to volumes inside the migration-destination storage apparatus. The user can make settings related to migration-source volumes and migration-destination volumes in a migration plan, and can establish a mid-process control plan for modifying the migration plan in the middle of processing. If a failure occurs in the migration-destination storage apparatus subsequent to the commencement of data migration processing, a processing method controller either cancels or temporarily halts the data migration processing, or changes the migration destination, on the basis of the mid-process control plan. When changing the migration destination, a previously selected alternate storage apparatus is selected as the new migration-destination storage apparatus. When a failure occurs in the alternate storage apparatus, yet another alternate storage apparatus is selected. | 03-19-2009 |
| 20090248759 | Backup management method in a remote copy environment - Provided is a computer system which is capable of backup operation with a minimum count of volumes in a remote copy environment when a disaster or the like causes a storage system to stop working normally. The computer system has a host computer, a first storage system, a second storage system, and a management computer. The first storage system contains a data volume which stores data requested by an application to be written. The second storage system contains a mirrored volume to which data stored in the data volume is copied. The computer system is characterized by being configured to receive an input of a policy about backup processing executed in backup volumes and set a configuration of the first storage system and a configuration of the second storage system under the received policy. | 10-01-2009 |
| 20100058012 | Backup Data Management Method in Which Differential Copy Time is Taken Into Account - Provided is a computer system, comprising a storage system and a management computer. The management computer manages differential copy start times, differential data amounts of first pairs, and a data amount that can be copied in differential copy per unit time; identifies one of the first pairs for which the differential copy is to be started and a start time of the differential copy; subtracts the data amount of differential copy per unit time that is allocated to the identified one of the first pairs from a differential data amount of the identified first pairs; add the unit time to the identified start time; judges that the differential copy has been finished at a time when the subtracted differential data amount reaches zero or less; and calculates time zones in which the first pairs execute differential copy based on the time at which differential copy has been finished. | 03-04-2010 |
| 20100332784 | STORAGE SYSTEM AND STORAGE SYSTEM DATA MIGRATION METHOD - This storage system modifies the migration plan in accordance with the state of the migration destination when a plurality of volumes are migrated all at once. Migration-source volumes are migrated collectively to volumes inside the migration-destination storage apparatus. The user can make settings related to migration-source volumes and migration-destination volumes in a migration plan, and can establish a mid-process control plan for modifying the migration plan in the middle of processing. If a failure occurs in the migration-destination storage apparatus subsequent to the commencement of data migration processing, a processing method controller either cancels or temporarily halts the data migration processing, or changes the migration destination, on the basis of the mid-process control plan. When changing the migration destination, a previously selected alternate storage apparatus is selected as the new migration-destination storage apparatus. When a failure occurs in the alternate storage apparatus, yet another alternate storage apparatus is selected. | 12-30-2010 |
