Abstract: A file server apparatus includes a memory which stores a program for controlling storage of data of a file in a storage apparatus, and a processor which executes the program. The processor manages a capacity of a storage area of an archive system in which a file stored in the storage apparatus is archived and manages a used capacity of the storage area. When receiving a write request of a file, the processor calculates a used capacity of the storage area of the archive system where a file related to the write request is archived and determines whether or not the file related to the write request can be archived in the archive system based on the capacity of the storage area of the archive system and the calculated used capacity. When determining that archiving cannot be performed, the processor notifies the host computer of an error.

Abstract: Proposed are a computer system and a management method capable of localizing influence from a failure of a physical node and preventing influence from the physical node failure from spreading.

Abstract: The present invention relates to a system that includes one or more logical volumes for storing data; a snapshot producing section for producing snapshots for the logical volumes based on a pre-scheduled snapshot acquisition time; a remote copy section for remote copying difference data for the snapshots based on pre-scheduled remote copy start times; and a scheduling section for re-scheduling the time of one or more of an Nth snapshot acquisition time, an remote copy start time, and an (N+1)th remote copy start time, in such a manner that remote copying starting at the Nth remote copy start time finishes by the (N+1)th remote copy start time.

Abstract: Proposed are a remote copy system and a remote copy control method capable of performing the operation of remote copy according to the user's usage status. Resource information representing a resource usage status is collected from a first storage apparatus installed at a primary site and a second storage apparatus installed respectively at one or more secondary sites, a transfer mode of differential data between snapshots to be transferred from the first storage apparatus to the second storage apparatus based on the collected resource information, and the first and second storage apparatuses are controlled so as to transfer the differential data from the first storage apparatus to the second storage apparatus based on the decided transfer mode.
