20100082925 | MANAGEMENT COMPUTER USED TO CONSTRUCT BACKUP CONFIGURATION OF APPLICATION DATA - According to the present invention, it is possible to construct a backup configuration of a particular application data, without influencing data of another application. A management computer is coupled to a host computer on which an application operates, and to a storage apparatus that includes a plurality of volume groups each having one or more logical volumes. At least one of the logical volumes is allocated to the application. The management computer includes a volume group overlapping use determination part and a backup policy determination part. When the backup of the volume group to which one logical volume belongs is configured, the volume group overlapping use determination part determines whether there is another application that uses the volume group. The backup policy determination part determines whether there is set, for another volume group, backup policy information same as that set for the application. | 04-01-2010 |
20100274767 | BACKUP METHOD FOR STORAGE SYSTEM - The present invention provides a backup method that makes it possible to specify the recovery-enabled time of an application even in a case where a backup has been performed without staticizing the application. In response to a first instruction from a management computer, a storage system backs up a first volume to a second volume at a first time while a first host computer continues to process an application. In response to a second instruction from the management computer, a second host computer reads out the data of the second volume and acquires a second time that is the time at which the application is recovery-enabled. The management computer stores the relationship between the backup and the second time in backup catalog information. | 10-28-2010 |
20110078395 | COMPUTER SYSTEM MANAGING VOLUME ALLOCATION AND VOLUME ALLOCATION MANAGEMENT METHOD - In a management computer which manages a storage system including a main logical volume and subsidiary logical volumes, when the access volume to the main logical volume exceeds a threshold value, a subsidiary logical volume associated with a physical volume having higher input/output performance than the physical volume associated with the main logical volume is selected. When the migration time of the data stored in the physical volume corresponding to the selected subsidiary logical volume is within a prescribed time period, then data stored in the physical volume corresponding to the main logical volume is migrated to the physical volume corresponding to the selected subsidiary logical volume, and the physical volume corresponding to the selected subsidiary logical volume is associated with the main logical volume. | 03-31-2011 |
20120102280 | MANAGEMENT SERVER AND DATA MIGRATION METHOD - The data backup processing time is shortened by improving the efficiency of data duplicate removal in the storage apparatus. | 04-26-2012 |
20120137303 | COMPUTER SYSTEM - Provided is a computer system capable of reliably eliminating duplicated data regardless of the size of the data write unit from the host computer to the storage subsystem or the management unit size in the elimination of duplicated data. | 05-31-2012 |
20120144002 | CLUSTER STORAGE SETTING METHOD, SYSTEM, AND MANAGEMENT SYSTEM - A storage cluster including a first storage apparatus and a second storage apparatus is defined. Communication between the first storage apparatus and the second storage apparatus uses a first network and an access request from a host computer uses a second network. Each of the first and second storage apparatuses defines internal LUs by using storage devices included in that storage apparatus. The first storage apparatus defines other internal LUs by using internal LUs of the second storage apparatus and the second storage apparatus defines other internal LUs by using internal LUs of the first storage apparatus. | 06-07-2012 |
