Abstract: Provided is a backup system including a storage system and a backup server, in which the backup server includes a ledger for managing a copy number and a backup acquisition date and time for each backup image, a data volume that stores data accessed by a business server, a backup image volume that stores a plurality of backup images at different time points of the data volume, an access volume having a volume ID for accessing the backup image from the backup server, and a data protection area including at least one volume having an internal volume ID instead of the volume ID for accessing from the backup server are configured in the storage system, and the backup image stored in the data protection area and the access volume are associated, and the backup image in the data protection area is provided to the backup server.

Abstract: Backup data equivalent to the maximum number of generations to be held can be secured even when backup data is locked. When locking of prohibiting overwrite of one or more storage areas is performed, a backup server prepares a new backup management table and uses the backup management table and an archive management table, which is the past backup management table, to store the backup data equivalent to the maximum number of generations to be held into a storage system.

Abstract: This management system for a computer system including a plurality of elements for which performance values are to be monitored generates one or more plans on the basis of: a performance value history of a specific bottleneck (an element that has been identified as the cause of a detected failure); management information that includes information indicating, for each countermeasure, the relation between a plurality of countermeasure attributes and a plurality of bottlenecks; and a countermeasure attribute corresponding to the specific bottleneck, and displays the one or more plans thus generated. Each of the displayed one or more plans includes one or more countermeasures. In each of the displayed one or more plans, each of the one or more countermeasures is classified into one of a plurality of countermeasure types.

Abstract: A management system includes an interface device coupled to a computer system including a plurality of resources including resources of a plurality of resource types and a processor coupled to the interface device. The processor allocates, to a tenant environment, a resource of a resource type, which is different depending on an XaaS (X as a Service), among the plurality of resources including resources of a plurality of resource types and provides a plurality of tenant environments including a plurality of XaaSs. The processor manages, as low-order resources, resources lower in order than the resources allocated to the tenant environments, among the plurality of resources including resources of a plurality of resource types. When receiving a resource change request, the processor executes change processing on at least one of the low-order resources among the resources managed as low-order resources.

Abstract: A computer system in an embodiment comprises a storage apparatus, a host computer, and a copy control program. The storage apparatus performs copy operations of volumes allocated to a guest OS of the host computer. The copy control program obtains volume information of the guest OS from a VM control program at a given time. The control program compares the information with previous volume information of the guest OS and performs volume copy control for the guest OS in accordance with the comparison result. This process achieve appropriate copy operations even if the association relationship between the guest OS and volumes is changed during system operation.

Abstract: A data storage or management method is provided which allows both a content object-based access and a file-based access. A first request for storing a content object in accordance with the processing of an application program executed in a host is sent to an object archive control functionality executed in the host, an intermediate server, or a storage apparatus. The object archive control functionality generates an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier, and a plurality of file names corresponding to a plurality of fields contained in the content object. The storage apparatus stores a directory having the directory name and the plurality of files having the plurality of file names in accordance with the second request.
