Description

Contents migration and on-line back-up system of a complex system

The present invention relates to a content migration and online backup system of a complex system capable of increasing the processing speed through the parallel processing of file data stored and managed on the same or different operating systems and providing stable content file data.

To survive in today's fast-changing market, where there is a need for rapid change and intense competition, the Internet is spreading rapidly in various parts of society and information is continuing. Accordingly, large-scale data is generated and managed by various systems such as electronic payment systems, electronic document management systems, knowledge management systems, etc., which are distributed not only to private enterprises but also to governments and affiliated organizations.

Since the data may include a large amount of files such as a multimedia file in addition to a general document file, the data is file data that is treated as an attached file beyond the format of a typical database in a table form. The file data used in the above systems increases exponentially with the dissemination and development of each system, and the necessity of management thereof becomes more important.

1 is a block diagram illustrating a conventional file system.

Referring to FIG. 1, an application 10, which is a database client side of each system, and a file system 30 are connected through a network 20. The file system 30 includes a network interface 31 for connecting to the network 20, and the file server 32 is connected to the network 20 through the network interface 31.

The file server 32 is connected to a storage unit 33, which is a physical storage means such as a hard disk drive for storing data, and a backup storage unit 34 for backing up data. The backup storage unit 34 generally backs up data by compressing and storing data on a magnetic tape through a tape drive. Alternatively, in the conventional file system, a hard disk drive may be added to the storage unit 33 to back up data or to increase storage capacity.

The expansion of the storage unit 33 for the expansion of the storage capacity is performed by shutting down the file system and keeping it offline with the network 20, and then by the administrator's manual operation. Drives are expanded or replaced, and backups are taking place. Since this is an expansion of the storage capacity in a single system, the load of the file server 32 that manages it increases according to the degree of expansion, which causes a slowdown of the system and further causes a data error.

On the other hand, in order to load the data backed up through the backup storage unit 34 back to the online database, that is, restore the file system and shut down (Shut down), and then offline with the network 20, the administrator's manual work The data was recovered by

Because of this characteristic, the conventional file system has not been organically backed up or restored, and the limited backup function provided in some cases is also offline. Therefore, in the application 10, the data to be viewed is included in the backed up data. There was a drawback of not being able to read it at all or taking a lot of time for offline work.

In the conventional system, since a file server managing a storage device must be operated on a single operating system, interoperability between systems operating on different operating systems that may exist in an organization is difficult.

For the above reasons, there was a difficulty in integrated management of content file data interspersed by various systems in a single organization and integrated management of content file data separately managed by various systems in multiple organizations.

Therefore, the present invention to solve this problem, while increasing the processing speed through parallel processing of the file data stored and managed on the same or different operating system and at the same time the data processing capable of the integrated service of stable content file data in a large system The purpose is to provide a content migration and online backup system of a composite system.
