Method and means for backup and restoration of a database system linked to a system for filing data |
摘要 |
In a database system with linkage between data in the database system and files in a system for filing data which is external to the database system ("the filing system"), backup and restoration of the database are coordinated with the filing system. Backup of a referenced file is initiated when the file is linked to the database system. The file backup is asynchronous to the linking process. When database backup occurs, all unfinished file backups are accelerated and completed before the database backup is declared successful. When a database is restored to a state with reference to files in a file manager, the database system causes the file manager to ensure that referenced files are linked to the database system.
