Abstract: In an approach for writing data on a tape using a file system, a processor receives a first write request of a first file. A processor obtains data of the first file. A processor writes the data of the first file on a tape. A processor receives a second write request of a second file prior to completion of writing the data of the first file on the tape. A processor adds information about the second file to a first list, wherein the first list includes files waiting to write. Subsequent to writing the data of the first file on the tape, a processor obtains data of the second file based on the first list. A processor writes the data of the second file after the first file on the tape.

Abstract: An information providing system and method, including a computer, for providing time taken to read a file, which includes an acquisition unit.

Abstract: Restoring a data processing system. Files on one or more storage devices of a data processing system are backed up to magnetic tape recording media. Metadata associated with the backed up files is recorded, including magnetic tape identification and tape location for each backed up file. Files on the one or more storage devices are identified that meet a selection policy for files required for rapid restoration of the data processing system. An index list is generated of the identified files and their associated magnetic tape metadata. The index list is sorted by magnetic tape identification and magnetic tape location. In response to a request to restore the data processing system, the identified files on the sorted index list are restored in magnetic tape identification and magnetic tape location sort order. Operation of the restored data processing system is then begun in accordance with the restored files.
