Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a backup system for files recorded on a server.
[0002]
[Prior art]
A server connected to a LAN or the like and storing data may be configured to back up data to a recording medium such as an MO or a DVD-ROM for protection of the stored data. However, backup to a recording medium takes time, and when trouble occurs, recorded data cannot be used immediately.
[0003]
In some cases, a high-end model of a server is configured to equip several hard disks, detect signs of a failure, and store data on an independent hard disk. In this type of server, if a failure occurs in the server body, the stored data cannot be used unless the server body is restored or the hard disk is not connected to another server. Furthermore, servers with this function are often expensive.
[0004]
There is also a server configured to store a plurality of the same file as a mirror when storing data. However, the mirror file is used, for example, when the file is damaged while the original file is being revised. However, the mirror file is not used as a backup when the server is damaged.
[0005]
Also, if you want to check the results of the backup that is automatically performed on the server, you need to check the copied files or monitor a large number of logs displayed on the screen when copying.
[0006]
It is desired that the backed up data can be used promptly in an emergency.
It is desirable that the result of backup can be easily checked.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to provide a data backup system that can use backed up data quickly in an emergency.
Another object of the present invention is to provide a data backup system that can easily confirm the result of backup.
[0008]

The means for solving the problem will be described below using the numbers and symbols used in [Embodiments of the Invention]. These numbers and symbols are added to clarify the correspondence between the description of [Claims] and the description of [Embodiments of the Invention]. It should not be used to interpret the technical scope of the described invention.

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of an automatic data backup system between servers according to the present invention will be described below with reference to the accompanying drawings.
[0017]
The configuration of the present invention will be described with reference to FIG.
The server-to-server automatic data backup system includes a plurality of file servers 10, 20,. Are connected to the groupware server 1, the groupware personal computer 3, and other terminals (personal computers) used by users.
The user accesses the file servers 10, 20,... From his / her personal computer, uses necessary data and programs, and saves work results in the file servers 10, 20,. The file is stored on a hard disk for normal use.
In this embodiment, an example in which the A file server 10 and the B file server 20 are installed is shown, but the number is not limited to two as long as there are a plurality.
The A file server 10 includes a CPU 11, a normally used # A1 hard disk 12, and a backup # A2 hard disk 13. One or more hard disks may be used as long as they have the required capacity. When there is one hard disk, the inside is divided into a normally used area and an area for backup.
The CPU 11 executes a backup program for performing a backup copy.
Similarly, the B file server 20 includes a CPU 21, a # B1 hard disk 22 for normal use, and a # B2 hard disk 23 for backup. The CPU 21 executes a backup program for executing a backup copy.
[0018]
The CPU includes an arithmetic unit, and based on the backup program, the time or cycle of performing the backup designated by the user, the backup target, and the information of the copy destination, the data of its own file server is copied to another copy destination. Copy to the backup hard disk of the file server.
Further, the CPU includes an arithmetic unit, stores the copied log in a text file using a backup program, extracts necessary data from the text file, and transmits the extracted data to the groupware server 1.
[0019]
The groupware server 1 includes a CPU 2 and performs data processing of groupware represented by notes or the like. The groupware server 1 processes a part of the log received from the file server so that the log can be browsed by the groupware.
[0020]
The groupware personal computer 3 includes a CPU 4 and can perform various data processing using the groupware. The server administrator can use the groupware personal computer 3 to view a part of the log processed as a backup processing result.
[0021]
FIG. 3 shows an example of a screen displayed when viewing the backup processing result.
On the screen 50, a server name 51, an execution date 52, a start time 53, an end time 54, a required time 55, a target file number 56, a copy execution number 57, and a result 58 are displayed. The user can be instructed to display the backup processing result for the file server specified by the user, or all the results, only errors, or the date or period can be displayed.
[0022]
FIG. 4 shows an example of a screen 70 on which only an error in the backup processing result is extracted and displayed. The screen 70 displays a server name 71, an execution date 72, a start time 73, an end time 74, a required time 75, a target file number 76, a copy execution number 77, and a result 78.
When an error occurs, it is preferable that information be sent to the server administrator by e-mail or the like.
[0023]
Next, the flow of the present invention will be described with reference to FIG.
The server administrator inputs conditions including designation of a copy destination for backup processing (S1) and scheduling of backup processing (S2). The input may be input from the groupware personal computer 4. It is preferable that an input program be prepared in the groupware and specified to a target file server.
[0024]
The CPU of each file server copies the file stored in its own hard disk to the backup hard disk area of another file server at the time or cycle designated by the server administrator by the backup program (S3).
Specifically, the CPU 11 of the A file server copies the data of the # A1 hard disk 12 of the A file server 10 to the backup # B2 hard disk 23 of the B file server 20. Similarly, the CPU 21 of the B file server 20 copies the data of the # B1 hard disk 22 of the B file server 20 to the backup # A2 hard disk 13 of the A file server 10.
If there are three or more servers, the designation may be made sequentially so that all servers can be backed up.
In this way, by backing up files across a plurality of file servers, even if one file server fails, if the backup disk of another server is made available by sharing it etc., it can be used immediately. Data can be used.
[0025]
Further, the CPU of each file server saves the log at the time of performing the backup in a text file (S4).
[0026]
Each file server transmits all or necessary contents of the log to the groupware server 1. The groupware server 1 extracts a necessary part from the received log and processes it so that it can be browsed by the groupware (S5).
[0027]
The server administrator can browse the backup result from the groupware personal computer (S6).
[0028]
In this embodiment, an ordinary personal computer can be used without using an expensive server as a file server.
Although the reliability of the personal computer may be lower than that of the dedicated server, the result of the backup processing can be easily confirmed, so that the server administrator can quickly respond.
[0029]
In this embodiment, even if one server fails, the file can be used immediately if the backup file of the other server is shared. Therefore, it is possible to minimize the stoppage of the business due to the server failure.
[0030]
【The invention's effect】
The server-to-server automatic data backup system of the present invention can use the backed up data immediately in an emergency.
The server-to-server automatic data backup system of the present invention can easily confirm the backup result.
