摘要： A method and apparatus which provide solutions for avoiding journal overflow in after and before journal methods of a backup and recovery system used with a storage system. The after journal method solutions, which are conducted when the amount of free space reaches a threshold, include periodically taking a new snapshot and deleting the oldest journal, periodically taking a new logical snapshot and deleting the oldest journal, stopping the taking journal entries when the journal volume is full, and stopping the taking journal entries when the journal volume is full and then switching to bitmap management. The before journal method solution, which is conducted when the amount of free space reaches a threshold, includes applying wrap-around overwriting to overwrite the oldest journal entry by the newest journal entry.

摘要： The invention provides a storage system which can estimate a necessary capacity at the time of acquiring a snap shot copy without actually sampling the snap shot copy, and a control method of the same. In a storage system, a disk control unit monitors a write instruction from a host machine for a fixed period, and calculates a capacity necessary at the time of a snap shot, on the basis of the monitored information for the fixed period, in the case of receiving an instruction of calculating the capacity necessary at the time of acquiring the snap shot which makes it possible to refer to the data at a certain time point within a disk unit.

摘要： A computer system which has a plurality of computers and a storage device subsystem connected to the plurality of computers. The storage device subsystem has a plurality of storage devices and a plurality of interfaces, through which the subsystem is connected to the computers. One of the plurality of computers has a management means for holding therein data indicative of the storage devices and a connection relationship between the computers and storage device subsystem. Each computer, when wanting a new device, informs the management means of its capacity and type. The management means receives its notification and selects one of the storage devices which satisfies the request. And the management means instructs the storage device subsystem to set predetermined data in such a manner that the computer can access the selected device. The management means also returns predetermined data to the computer as a device assignment requester, the assignment requester computer modifies setting thereof to allow the computer in question can use the assigned device.

摘要： In creating replicas to data of a storage volume in a storage system, a technique in which labor for issuing instructions from a processor can be reduced and then data consistency of related volumes can be secured is provided. A single replication instruction including designated information is issued for data of a logical unit serving as a copy source and a copy destination from a replication-control program of the processor. A control unit of the storage system possesses a multiple-replica creation program which enables a processing for creating replicas while securing the data consistency when an access such as a update or reference occurs for a group including a plurality of pairs of copy-source volume and copy-destination volume based on reception of the instruction. A save volume is provided to identify and control data save and update state by copy-source save information and copy-destination update information at the shared memory.
