摘要： A data processing system has a plurality of storage systems. In this system, data replication is performed at high speed and efficiency while maintaining data integrity. In addition, when failure has occurred in a configuration element, the time necessary to resume the data replication is reduced. In accordance with an instruction from first host computer, updating of replication-target data and creation of a journal are performed in a storage system A; and updating of replication data and creation of a journal are performed in a storage system B. A storage system C retrieves a journal from the storage system B in asynchronization with the updating, and performs updating of replication data. When failure has occurred in the storage system B, a journal-retrieving end is altered to the storage system, and the replication data is updated in accordance with the retrieved journal.
摘要翻译：数据处理系统具有多个存储系统。在此系统中，数据复制以高速和高效率进行，同时保持数据的完整性。另外，当配置元件发生故障时，恢复数据复制所需的时间减少。根据来自第一主计算机的指令，在存储系统A中执行复制目标数据的更新和日志的创建; 并且在存储系统B中执行复制数据的更新和日志的创建。存储系统C与更新异步地从存储系统B检索日志，并且执行复制数据的更新。当存储系统B发生故障时，日志检索端被更改为存储系统，并且复制数据根据检索的日志被更新。

摘要： The data is automatically recovered to a desired arbitrary point in an external storage without imposing a burden on the host computer. An application on a host computer instructs data recovery control processing of a disk control apparatus to set a recovery opportunity. It is possible to register arbitrary plural points as a recoverable point by setting a recovery flag included in journal data. In the case in which data is recovered due to occurrence of a failure or the like, the application requests a list showing recovery opportunities which have already been set. The application designates a point to which data is recovered on the basis of the recovery opportunity list. The disk control apparatus recovers the data to the designated point on the basis of a backup disk and a journal disk.

摘要： A data processing system includes at least a first storage system, a second storage system and a third storage system. The third storage system maintains a replication of data stored in the first storage system. When updating data in the first storage system, the first storage system updates the replication of data stored in the third storage system and creates a journal. The journal is formed from a copy of data used for update and update information such as a write command for update, etc. The second storage system also maintains a replication of data stored in the first storage system. The second storage system obtains the journal, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system. When updating data stored in the third storage system corresponding to data stored in the first storage system, the third storage system creates a journal using data update numbers created in the first storage system. When the first storage system fails, the second storage system obtains the journal from the third storage system, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system.

摘要： The present invention manages the information of storage apparatuses inside a single storage apparatus in an integrated fashion, under a heterogeneous storage environment in which a variety of storage apparatuses are distributed and deployed on a plurality of sub-networks. A wide-area network comprises a plurality of sub-networks, and a plurality of storage apparatuses are disposed on the respective sub-networks. A storage apparatus, which constitutes the connection source, issues query commands and collects storage information from respective external storage apparatuses based on conditions input from a user. When external resources matching the user-desired conditions are extracted, these external resources are displayed on a management terminal. When the user selects a desired external resource, this external resource is connected to a virtual intermediate volume and provided to a host.
