FILE STORAGE APPARATUS AND DATA MANAGEMENT METHOD

摘要

A file storage stores a client file (a file from a client) in a first file system (FS), stores metadata of the client file in a backup file in a second FS, and backs up the backup file to the first FS at a backup process start time. The file storage creates consistency file management information specifying a backup file having been backed up and a client file at that time point, acquires, when a file specified by the consistency file management information is transmitted to an archive storage apparatus, data identification information for identifying the transmitted file in the archive storage apparatus, and associates the data identification information with the transmitted file.

主权项

1. A file storage apparatus coupled to a client computer and an archive storage apparatus, the file storage apparatus comprising:
a first file system; a second file system configured to store a database including a database file; an application unit configured to store a client file that is a file received from the client computer in the first file system and store metadata of the received client file in the database file; a transmission file management information creating unit configured to create transmission file management information specifying files to be transmitted to the archive storage apparatus for archiving among a plurality of files which are stored in the first file system and which include a client file and a database file; an archive processing unit configured to transmit a file specified by the transmission file management information to the archive storage apparatus at a prescribed archiving process start time; a backup processing unit configured to back up a backup file of the database to the first file system at a prescribed backup process start time; a consistency file management information creating unit configured to create consistency file management information specifying a backup file having been backed up to the first file system and a client file in the first file system at a time point when the backup file had been backed up; and a consistency monitoring unit configured to monitor a file transmitted by the archive processing unit to the archive storage apparatus, to acquire, when a file specified by the consistency file management information is transmitted to the archive storage apparatus, data identification information for identifying the file transmitted to the archive storage apparatus in the archive storage apparatus, and to associate the acquired data identification information with the file specified by the consistency file management information.
