    摘要: A backup processing method for backing up data to be used by a data-processing computer system comprises selecting resources in a usable state from a plurality of resources necessary for the data to be used by the data-processing computer system, selecting switches in a usable state from a plurality of switches needed to form routes among said selected resources, and executing backup processing by using the secured resources and routes when the resources and routes necessary for backing up data to be used by the data processing computer system are secured to form multiple backup subsystems.

    摘要: The data up to a point of time whereat failure has occurred will be restored at high speed at a remote site without imposing any burden on a host. The first storage system on the master side processes an I/O request from the host, and as a result of I/O processing to the second storage system on the remote side, transmits the update data. The second storage system retains data received from the first storage system as update log data. The host transmits a command for settling a state of an application to the first storage system as data, and the first storage system transmits the data to the second storage system. The host and the second storage system both retain an identifier corresponding to the command, and relate the identifier to the log data. Thereby, the host designates the identifier at any given time, whereby the second storage system restores the data at any given time.

    摘要: When a logical volume in a first storage box is transferred to a second storage box, information of an access object such as a network communication protocol possessed by a host which communicates with the first storage box is changed to change a network route for accessing the transferred logical volume. Logical volume transfer is notified from the first storage box to the host by using an ICMP Redirection Error message or the ARP protocol.
