    摘要: A file management apparatus is used in an information processor using a media exchange type storage device including a plurality of storage media, at least one data access device, and a storage media exchanging means as an external storage device. The file management apparatus includes a data block management device for dividing storage regions of the respective storage media into data blocks of fixed capacity and managing the use states of the divided data blocks. A data block allocation device allocates unused data blocks shown by the data block management device to a file to which a writing request from the information processor has been given.

    摘要: A backup unit comprises a first storage means containing at least one program and a setup file in which the operating environment of that program is written; a second storage means used when the first storage means has a fault; a duplication means for duplicating the program and the setup file contained in the first storage means, into the second storage means; and an identifier conversion means for converting identifiers included in the setup file of the first storage means and relating to the first storage means, into identifiers relating to the second storage means, when the duplication is performed. Therefore, when the operation of an information processor is stopped due to a fault in the first storage means, the second storage means enables temporary operation of the information processor. In addition, it is possible to employ, as the second storage means, a recording medium that is lower in price and writing speed than the first storage means.
