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.
