Abstract

PURPOSE:To reduce the labor cost by starting a backup job of a backup management master by a backup control means to back up files without manual operation even at night. CONSTITUTION:A backup control means 2 reads out contents of a backup management master 3 to retrieve a backup name as the backup object and a backup time at which backup should be designated. Based on this retrieved information, the means 2 starts the backup job at the designated backup time to take a backup file of the object file stored in a secondary storage device 4 on an assembled-type cassette magnetic tape device 1. The stored result is returned to the means 2, and the means 2 writes the stored result in the processing result of the management master 3.

[Detailed description of the invention]

0001

FIELD OF INDUSTRIAL APPLICATION The present invention is applied to a backup device for an information processing device. In particular, information processing equipment is a collective magnetic tape storage device (e.g., cassette type, cartridge type,
This invention relates to a backup device for data preservation using CGMT.

0002

2. Description of the Related Art Conventionally, backup devices have used open-reel magnetic tape to store data on the magnetic tape when an operator executes a job and loads the magnetic tape into the device.

0003

[Problems to be Solved by the Invention] However, with such conventional backup devices, manual operation is required to load the magnetic tape, and an operator also needs to give instructions for backup, making it difficult to operate unattended at night. However, there was a disadvantage in that it was not possible to do so, and the labor costs were high.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks, and aims to provide a backup device that can perform unmanned backup even at night without human intervention, and can reduce labor costs.

[0005]

[Means for Solving the Problems] The present invention provides a backup device equipped with a backup means for accumulating files stored in a secondary storage device as backup files, wherein the backup means includes a backup management system that stores backup management information. a master, a collective magnetic tape storage means that automatically loads magnetic tape and stores the backup file based on input control signals, and starts a backup job based on the contents of the backup management master, and and backup control means for reading the corresponding file from the storage device, applying the control signal to the collective magnetic tape storage means to store the read file, and writing the storage result to the backup management master. Features.

Further, in the present invention, the backup management information can include a backup file name, backup time, and processing result.

Furthermore, the collective magnetic tape storage means may be a collective cassette magnetic tape device or a collective cartridge magnetic tape device.

[0008]

[Operation] The backup means uses a backup control means to start a backup job based on the backup information of the backup management master, reads the corresponding file from the secondary storage device, and automatically loads the magnetic tape. A control signal is given to the tape storage means to store the read file as a backup file, and the storage result is written to the backup management master.

[0009] Furthermore, the backup management information can include a backup file name, backup time, and processing result.

Furthermore, the collective magnetic tape storage means can be a collective cassette magnetic tape device or a collective cartridge magnetic tape device.

[0011] With the above, backup can be performed unmanned even at night without human intervention, and personnel costs can be reduced.

Embodiments Examples of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a backup device according to an embodiment of the present invention.

In FIG. 1, the backup device includes backup means for accumulating files stored in the secondary storage device 4 as backup files.

The feature of the present invention is that the backup means includes a backup management master 3 that stores backup management information, and automatically loads a magnetic tape and stores the backup file based on an input control signal. A collective cassette magnetic tape device 1 and a backup management master 3 serve as collective magnetic tape storage means for
starts a backup job based on the contents of the file, reads the corresponding file from the secondary storage device 4, gives the control signal to the collective cassette magnetic tape device 1 to store the read file, and stores the storage result. It is characterized in that it includes a backup control means 2 for writing to a backup management master 3.

[0015] Furthermore, the backup management information includes a backup file name, backup time, and processing result.

The operation of the backup device having such a configuration will be explained. In FIG. 1, the backup control means 2 reads the contents of the backup management master 3 and searches for the name of the backup file to be backed up and the backup time specifying the point in time to back it up. Based on the retrieved information, the backup control means 2 starts a backup job (standardly provided as a computer utility) at the specified backup time and transfers data to the collective cassette magnetic tape device 1. Next, take a backup of the target file stored in the storage device 4. The storage result is returned to the backup control means 2. The backup control means 2 writes the stored results to the processing results of the backup management master 3.

Since the collective cassette magnetic tape device 1 has means for automatically loading cassette magnetic tapes, backup can be performed without human intervention.

[0018]

[Effects of the Invention] As explained above, the present invention has the excellent effect of enabling unattended backup even at night without human intervention and reducing labor costs.
