At the same time, the time elapsed from the time point when the production of the file is complete through the present time point is also decided by the computer 1. Then the back-up necessity is decided for the file based on the file importance degree, the work amount and the elapsed time. This deciding result is displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus capable of writing a file in a storage device such as a hard disk device to another storage device such as a magneto-optical disk device or a cassette streamer for the purpose of backup.

[0002]

2. Description of the Related Art In a small computer system such as a personal computer or a word processor, a floppy disk device (FDD) and a hard disk device (hereinafter referred to as HDD) are often used. HDDs are not permanent storage devices and may suffer from internal data corruption called "crash". This crash may occur not only due to the mechanical factors of the HDD but also due to software or a computer virus. Therefore, generally, files in the HDD are backed up by a cassette streamer (cassette type magnetic tape device).

[0003]

By the way, since the time required for backup is relatively long and the backup operation is troublesome, backup is often neglected. Further, if all files are backed up, the load on the backup recording medium will increase. Further, even if all files are backed up, if the backup is performed every time one file is completed, the work becomes complicated.

Therefore, an object of the present invention is to provide an information processing device which can perform backup rationally.

[0005]

The present invention for achieving the above object provides, in an information processing apparatus including a storage device configured to record a plurality of files on a first recording medium, in the first information storage device. A file for recording the file recorded on the recording medium on the second recording medium, a means for generating a signal indicating the necessity of backing up, and a display means for displaying the signal indicating the necessity. Information processing device. As described in claim 2, it is desirable to obtain the signal indicating the necessity of backup based on the signal indicating the importance of the file. Further, as described in claim 3, it is possible to obtain a signal indicating the necessity of backup based on the number of times the file is used (the degree of work of the file). Further, as described in claim 4, it is more preferable to obtain the signal indicating the necessity of backup based on the importance of the file and the number of times of use of the file (the degree of work of the file). Further, as described in claim 5, a signal indicating the necessity of backup, a signal indicating the importance of the file, and a signal indicating the number of times the file has been used,
It is desirable to obtain it based on the elapsed time from the completion of file creation.

[0006]

According to the present invention, a signal indicating the necessity of backup is displayed on the display means. As a result, the operator can reasonably know the necessity of backup and can perform the backup process with reasonableness. If backups are done reasonably well, neglecting them will cause very few problems. Moreover, since only the files that need to be backed up can be backed up, the waste of the backup recording medium is reduced. According to claims 2, 3, 4 and 5, more rational backup is possible. According to claims 3, 4 and 5, it is possible to back up a file that does not need to be backed up at the same time as the file is created until the need arises, so that it is possible to prevent the same file from being repeatedly backed up. it can.

Next, an information processing apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 shows a small computer system as an information processing device. This system is configured by connecting a computer 1, an HDD 2, a magneto-optical disk device (hereinafter referred to as MO) 3 and a floppy disk device (not shown) to each other by a bus 4. The computer 1 is a known device including a CPU (central processing unit) 5, a keyboard 6, a RAM (random access memory) 7, a ROM (read only memory) 8, a display device 9, and an interface 10. belongs to.

The HDD as the first storage device is a first recording medium disk 11 composed of a magnetic disk, a motor 12 for rotating the same, and a signal conversion magnetic head 13.
And a signal processing circuit 14 connected to the head 13. The first recording medium disk 11 includes a large number of tracks concentrically and has a storage capacity capable of storing a large number of files. Backup software and verification software are stored in advance on the first recording medium disk 11 of the HDD 2. Of course, the disk 11 also stores software called an operating system (OS) for controlling the execution of programs in the computer 1 and application software.

The MO3 serving as a second storage device includes a second recording medium disk 15 composed of a magneto-optical disk, a rotation motor 16 thereof, a magneto-optical recording / reproducing head 17, and
And a signal processing circuit 18. The second recording medium disc 15 has a larger storage capacity than the first recording medium disc 11 and can write a large number of files.

FIG. 2 shows a display on the display device 9 corresponding to the file management data in the file list recording area of the first recording medium disk 11. In this system, backup information, verify information, file importance information, file work amount (number of times of use) information, file creation date information (elapsed time information) in addition to file names in the file list storage area of the first recording medium disk 11 ) Are written, and these are displayed on the display surface of the display device 9 as shown in FIG.

The backup information consists of two types, information indicating whether or not a file is backed up and information indicating the necessity of backing up the file. In the backup information column of FIG. 2, “Complete” indicates that the backup of the file 1 is completed, “Necessary” indicates that the backup of the file 2 is necessary, and “Undecided” indicates that the files 3, 4 are currently in progress. Indicates that the backup of is not necessary and is undecided in the future. Even if the file 1 has been backed up, the display of "necessary" is added if the file 1 needs to be backed up by the subsequent update of the file contents.

The verification information is the verification of the backed up file, that is, in this example, the file backed up on the disk 15 of the MO3 and the file on the disk 11 of the HDD 2 are compared to determine whether or not they substantially match. It is made up of two types of information, that is, information indicating whether or not the work of checking whether or not it has been performed, and information indicating the necessity of verification. In the verification information column of FIG. 2, “completed” indicates that the verification of the file 1 has been completed, “required” indicates that the verification is necessary when the file 2 is backed up, and “undecided”. Indicates that the need for verification is undecided at this time.

The need for backup and verification is
File importance A and file work volume (number of times used)
Is determined based on the degree B and the degree C of the elapsed time of the file.

The importance A of the file is 0, 1, 2, 3,
Appears in 5 stages of 4. A severity level of 0 indicates that the file has no significance and there is no need for backup and verification. Severity 1 indicates that the file is somewhat important and there is some need for backup and verification.
The importance level 2 indicates that the importance of the file is normal and the necessity of backup and verification is also normal. The degree of importance 3 indicates that the file is somewhat important and the necessity of backup and verification is high. Severity 4 indicates that the file is very important and the need for backup and verification is very high. The importance A is entered by the creator of the file using the keyboard 6 when creating the file, and is written on the first recording medium disk 11. The importance of the file is of course determined by the file creator.

The degree B of the work amount (the number of times of use) of the file is determined by the mode of accessing the file and the number of times of access. When the file is accessed for reading (reading), the content of the file is not updated, so that the necessity of backup is not increased so much. On the other hand, when the file is accessed for writing or rewriting, the need for backup increases. Therefore, in the present embodiment, the degree of work of the file is determined according to the following. First, the integrated value N1 of the work load (number of times of use) of the file is calculated by the following formula. N1 = Nr + 5Nw However, Nr is an integrated value of the number of times of file read access, and Nw is an integrated value of the number of accesses for writing of the file. Here, Nr and Nw are not simply added, but Nw is weighted by a coefficient of 5 and added. next,
It is judged whether the integrated value N1 of the work amount of the file is within the range, and the degree N2 of the work amount of the file is determined. That is, when N1 is 4 or less, N2 is set to 0. N1
When N is 5 to 19, N2 is set to 1. N1 is 20 ~
In the case of 29, N2 is set to 2. When N1 is 30 to 39, N2 is set to 3. N2 when N1 is 40 or more
Is 4. N2 = 0 is the work amount of the file (number of times of use)
Is zero or very low, so there is virtually no need for backup, N2 = 1 means there is some work on the file, there is some need for backup, N2 = 2 means Since the amount of work on the file is normal, it indicates that the need for backup is also normal.
2 = 3 indicates that the amount of work on the file is relatively large, and thus the need for backup is somewhat high, and N2 = 4 indicates that the amount of work on the file is very large, and that the need for backup is very high.

The number of accesses Nr for reading a file and the number of accesses Nw for writing are measured by the computer 1 and are stored in the disk 11 of the HDD 2.
Is written in the file list recording area of. Further, the computer 1 executes the calculation of N1 = Nr + 5Nw, obtains the value of N2 based on this, and writes it in the list recording area of the disk 11.

In the file creation date column of FIG. 2, the creation completion date of each file is displayed. The data for this display is written in the file list recording area of the disk 11 of the HDD 2. The computer 1 obtains the elapsed time from the file creation completion time based on the difference between the creation completion date of each file and the current time, and divides the file list of the disk 11 into 0, 1, 2, 3, and 4 degrees. Write to the recording area. The degree 0 of elapsed time indicates 24 hours or less, the degree 1 indicates 25 to 48 hours, and the degree 2 indicates 49 to 7 hours.
2 hours are shown, degree 3 shows 73-106 hours, and degree 4 shows 107-130 hours. Although the degree of the elapsed time is not displayed in FIG. 2, it can be additionally displayed or displayed instead of the file creation date. If it is less than 1 hour, it is discarded.

The computer 1 judges the necessity of backup and the necessity of verification at the start of booting or at predetermined time intervals or in response to a request, and displays them on the display device 9.
That is, the computer 1 follows the predetermined program from the file list recording area of the disk 11 to determine the degree of importance A of the file, the degree B of the amount of work, and the degree C of the elapsed time.
Is read and an addition operation of A + B + C is performed, it is determined whether or not this value is 5 or more, and when it is 4 or more, information indicating that a file backup is necessary is written in the file list recording area of the disk 11. Then, the information in the file list recording area is read out and displayed on the display device 9 as shown in FIG. In the example of FIG. 2, A of file 3 is 3, B
Is 1, C is 1, and A + B + C is 5, so it is displayed that backup is required. The operator knows the necessity of backing up the file from the display of FIG. 2 and writes the file in MO3.

The files may be backed up multiple times for the same file. For example,
In FIG. 2, the file 1 has been written to both the first disk 11 and the second disk 15 after the first backup is completed. However, if the contents of file 1 are updated, the need for backup arises. The degree B of the work amount is reset to 0 when the backup is completed, and the new degree B is obtained according to the change of the work amount (the number of times of use) of the file thereafter. Computer 1
Determines the necessity of backup for the first backed up file 1 as well as the other files 2-4 which have not been backed up, and when necessary, it is necessary in the backup information column of FIG. Display that there is.

The necessity of verification after the backup is judged by the importance of the file. The computer 1 reads the importance A of the file after backup from the list of FIG. 2, and when the value is 2 or more, writes the information indicating that verification is required in the file list recording area of the disk 11. The information of this verification after that is read out and displayed on the display device 9 as shown in FIG. The operator sees the display of FIG. 2 and finds that it is necessary to back up and verify file 2. As a result, only files with high importance can be verified, and the rationality of verification can be improved.
