Use situations of storage devices utilizing a storage area network (SAN) are predicted and the devices are automatically managed on the basis of the predicted results. To manage the devices utilizing the SAN, there is established the policy prescribing actions each executed when some object to be judged satisfies some condition with regard to storage devices. Information concerning use situations of the devices is collected and a value of an object to be judged of the policy is calculated based on collected information to judge whether the value of the object to be judged satisfies a condition of the policy. When the condition is satisfied, the action of the policy is executed. The objects to be judged of the policy may be actual result values in the past, current values or prediction values in the future relative to use capacity of storages, the number of I/O operations of disk or fragmentation.

Storage device management method, system and program

Duplicate data obtained by copying and a volume containing it are flexibly managed according to the attribute of the file to be copied by a storage apparatus as is required by a user. When receiving a backup instruction for the file to be backed up, an instruction for a method managing the attribute of the object to be backed up and the duplicate data obtained by the backup of the object to be backed up is also received. In this case, the duplicate data and the volume name to store it are related, thereby managing the specified attribute.

Method, apparatus, and computer readable medium for managing back-up

A performance information monitoring method using computers includes the steps of accepting information on a group relating to a first computer in the first computer; storing the accepted group information in a storage in the first computer; accepting performance information from a second computer in the first computer; comparing performance information of the second computer previously stored in a storage with the performance information received from the second computer in the first computer; judging whether or not the second computer is included in the information of the group when finding a difference between the performance information in the comparison result; and transmitting an instruction to the computer included in the group information to change a performance information collection interval according to the judgment result.

Performance information monitoring system, method and program

To provide a file transfer method and system capable of making backups in a unified manner at backup sites and MSP (Management Service Provider) operating under an around-the-clock system with high reliability equipment. When data to be transferred such as backup is transferred between SAN (Storage Area Network) storing units to back up the data stored in the SAN, a data transfer instruction is sent to the transfer source and transfer destination of the data transfer via a network which is different from the SAN.

File transfer method and system

A backup or restore schedule is determined in an efficient manner. A backup definition creating unit in a management server reads a start time of a service managed by a job schedule unit, and sets a backup start time in a time zone in which the service is not executed.

System and method for data backup

A data transfer method which quickens the resumption of work execution in an environment in which works are executed by a plurality of computers according to a schedule. The work server identifies a work to be processed, identifies a file used by the identified work, and then restores the data of the identified file.

Data transfer method

An assigning system and an assigning method are provided for assigning a storage device or a unitary logical unit of the storage device. A VLU-LU correspondence table is provided which shows a correspondence between virtual logical units (VLU) virtually set in a host computer and logical units (LU) of a plurality of storage devices connected to a network. This table stores evaluation items of each storage device such as a delay time and an access frequency. An evaluation unit calculates an evaluation value of each evaluation item in the table, and a unitary logical unit of the storage is assigned in accordance with the evaluation value.
