Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the storage and storage of a large number of image data handled in, for example, printing, plate making, etc.
The present invention relates to an image data filing apparatus that performs a search, and particularly to a backup / recovery processing configuration that protects useful resources such as image data stored in the image data filing apparatus and management information for managing the image data.

[0002]

2. Description of the Related Art In a conventional image data filing apparatus (database apparatus for image data) which handles a large number of image data of this type, the image data to be handled is stored in, for example, a magneto-optical disk. Further, in order to cope with an increase in the number of image data to be handled, a plurality of magneto-optical disks storing image data are mounted, the mounted magneto-optical disks are switched, and the image data is stored in a desired magneto-optical disk. An automatic changer device for reading out desired image data from a predetermined magneto-optical disk is also provided. If the image data stored in a large number of magneto-optical discs is directly operated on the magneto-optical discs in this manner, the number of image data is large, so that the processing time for searching for the image data to be manipulated is increased. It will take a very long time.

Therefore, most of such image data filing apparatuses are provided with a so-called relational database system and indirectly operate the corresponding image data via the management information of the image data under the control of the system. Has been taken. This management information is constructed by constructing search data corresponding to image data in a one-to-one correspondence in accordance with a predetermined management system. Further, the search data is, for example,
It is composed of data for associating such as where on which magneto-optical disk the corresponding image data is stored, and keywords for searching the image data. For example, the management information is constructed according to a system in which the search data is classified for each customer and for each work unit. Further, the management information is made to correspond to a large number of image data, and is usually stored in a hard disk other than the magneto-optical disk storing the image data for the reason of increasing the processing speed.

In an apparatus having such a configuration, backup / recovery for protecting useful data such as image data having high asset value and management information for managing the image data from failure is important. Conventional backup /
The recovery is performed separately for the management information and the image data in order to make it possible to perform backup according to the different storage media and the difference in the data update frequency. That is, for backup of the management information, backup data of the management information is created on a magnetic tape or a magneto-optical disk (only for backup of the management information), and when a failure occurs, the backup data of the management information is stored on the hard disk. Recovery is performed by copying to. On the other hand, when backing up image data, for each file (corresponding to one image data), the specified image data is backed up to a magneto-optical disk for backup different from the magneto-optical disk in which the original image data is stored. All the data is created, and when a failure occurs, the backup data of the image data is recovered for each file by copying it to the magneto-optical disk in which the original image data was stored.

[0005]

However, the conventional example having such a structure has the following problems. That is, according to the conventional device, the management information and the image data are backed up / recovered separately, and after the recovery of any data, or the recovery of both data, etc. ,
Since each data is restored using the backup data created separately, there may be a mismatch such as that both data (search data and image data) do not have a one-to-one correspondence. There is a problem that the consistency is not guaranteed. In such a case, for example, if the search data corresponding to the valid image data has disappeared from the management information, the image data cannot be read out even though it is valid image data. If the search data is present in the management information despite the absence of data, the inconvenience of being able to search for image data that does not exist will occur.

Further, image data is backed up on a file-by-file basis, and a large number of files (image data)
When all are backed up at once, all the backup data of the specified file is created, so there is also a problem that the processing time is long. In such a case, the original image data search process or the like may be hindered, or the frequency of backup becomes low and the recovery level at the time of failure becomes low.

The present invention has been made in view of the above circumstances, and is intended to ensure consistency between the management information after recovery and the image data, and to shorten the processing time of backup of the image data. An object is to provide a filing device.

[0008]

The present invention has the following constitution in order to achieve such an object. That is, according to the invention of claim 1, a plurality of image data,
In an image data filing apparatus, which stores separately search data corresponding to each of the image data in accordance with a predetermined management system, respectively, and stores the stored image data by the management information. Management information backup means for backing up management information by creating management information backup data, image data backup means for backing up image data by creating backup data for the image data, and the management information Management information recovery means for restoring the management information by using the backup data of the management information created by the backup means, and restoration of the image data by using the backup data of the image data created by the image data backup means. After the recovery operation of the management information by the image data recovery means and the management information recovery means, or the recovery operation of the image data by the image data recovery means, the search data in the management information and the image data are in a one-to-one correspondence. If there is search data or image data with inconsistency as a result of the consistency check by the consistency check means for checking the consistency of whether or not it corresponds, the data is deleted from the management information. Alternatively, or by registering, the consistency restoration means for restoring the correspondence between the management information and the image data is provided.

According to a second aspect of the invention, in the image data filing apparatus according to the first aspect,
Update information for recognizing the update state of the image data after the backup is recorded is recorded, and the image data backup means performs the previous backup of the image data to be backed up based on the update information. After that, only the updated image data is backed up.

[0010]

The operation of the present invention is as follows. That is,
According to the invention described in claim 1, the backup and recovery of the management information and the image data are performed in accordance with the frequency of each data update, or each process for individually dealing with the occurrence of a failure in each data. It can be done independently by means. Further, after the recovery of the management information, the recovery of the image data, or the recovery of both data, the consistency check means sets the recovered image data and the management information to 1 The consistency is checked to see if it corresponds to one-to-one, and if there is inconsistent data, the consistency restoration means deletes the search data from the management information or registers the data so that both Since the data consistency is restored, the consistency between the management information and the image data is guaranteed even if each data is backed up / recovered independently.

According to the second aspect of the present invention, update information for recognizing the update state of the image data after the backup is recorded is recorded, and the image to be backed up is recorded based on the update information. By backing up only the image data for which the image data has been updated since the last time it was backed up, unnecessary backup can be omitted, so the processing time for backing up image data is reduced. It can be shortened. Note that image data is updated when image data is newly registered in a storage medium, image data stored in the storage medium is deleted, or image data is copied to another storage location. It means that the storage state of the stored image data has changed due to movement or the like. That is, the backup is performed when the correspondence relationship with the management information is changed.

Further, for example, if the information that stores the date and time of the previous backup and the date and time of the last update is stored as update information, the image data is updated after the previous backup from both dates and times. It is possible to determine whether or not there was. Alternatively, for example, if a flag is provided, backup is performed, then that flag is cleared, and if there is an update of the image data, if the flag information is configured as update information, then depending on the state of that flag, It is possible to determine whether or not the image data has been updated after the previous backup.

Next, the backup / recovery controller 8
Details of (FIG. 2) will be described. As described above, the backup / recovery control unit 8 includes the process selection unit 30, the management information backup unit 31, the image data backup unit 32, the management information recovery unit 33, the image data recovery unit 34, the consistency check unit 35, and the consistency restoration. And a part 36. Details of each part will be described below.

The process selecting section 30 allows the operator to select each process of the following backup, recovery and consistency check, and activates the selected process. In order to allow the operator to select, for example, a menu screen as shown in FIG. 6 is displayed on the output device 12, and the process selection unit 30 activates the process instructed by the operator from the input device 11 according to the menu screen. It should be noted that the activation of the consistency restoration unit 36 is performed by the consistency check unit 3 as described later.
It is configured to be activated from 5.

The processing procedure of the processing selection unit 30 will be described with reference to the flowchart shown in FIG. First, the menu screen is displayed and the operator waits for an instruction (step S1).
Next, a predetermined process is started according to the instruction from the operator (step S2). In step S3, the management information backup unit 31 is activated to back up the management information. In step S4, the image data backup unit 32 is activated to back up the image data. Further, in step S5, the management information recovery unit 33 is activated to recover the management information. In step S6, the image data recovery unit 34 is activated to recover the image data. Further, in step S7, the consistency check unit 35 is activated to check the consistency. If the termination is instructed, the process of the process selection unit 30 is terminated. When each processing of the management information backup unit 31, the image data backup unit 32, and the consistency check unit 35 is completed, the process returns to the process of step S1 and waits for a selection instruction of the process. When the processing of the management information recovery unit 33 and the image data recovery unit 34 is completed, step S7
Each of the consistency check units 35 is activated. this is,
This is to keep the consistency of each data after the recovery processing.

The management information backup unit 31 backs up the management information by copying the management information stored in the H / D 18 to the magneto-optical disk 16 dedicated to the management information backup. There is only one magneto-optical disk 16 dedicated to backing up management information, and the magneto-optical disk 16 is used by overwriting each time it is backed up. The magneto-optical disk 16 dedicated to backing up the management information also has "volume information", which is used for identifying the magneto-optical disk 16 and the like. In addition,
The operator confirms whether or not the magneto-optical disk 16 dedicated to the backup of the management information is mounted on a predetermined shelf in the auto changer device 15 before starting the backup processing of the management information by the processing selection unit 30 described above, If not, the magneto-optical disk 16 is mounted on a predetermined shelf. This predetermined shelf is a predetermined shelf number (for example, shelf number 1) for the magneto-optical disk 16 dedicated to the backup of the management information, and normally, the shelf has a magneto-optical disk dedicated to the backup of the management information. 16
Is installed.

The management information backup processing procedure is shown in FIG.
It will be described according to the flowchart shown in FIG. First, check whether other application programs are running in the device, and if they are running, wait for the processing to finish, and if other processing is not running, perform backup processing. Execute (step S10)
1). This is to prevent the management information from being referred to by other processes and to avoid the interference of the operation of the autochanger device 15.

Next, the magneto-optical disk control unit 5 is instructed via the system control unit 2 to mount the magneto-optical disk 16 dedicated to the backup of the management information in the predetermined disk drive 17a (or 17b) ( Step S1
02). As a result, the magneto-optical disk control unit 5 drives the autochanger device 15 so that the magneto-optical disk 16 dedicated to backing up the management information is removed from the shelf (for example, shelf number 1) on which the magneto-optical disk 16 is mounted. It is moved to the disk drive 17a (or 17b), the "volume ID" is read from the "volume information" of the magneto-optical disk 16, and the magneto-optical disk 16 mounted on the disk drive 17a (or 17b) stores the management information. It is checked whether it is the magneto-optical disk 16 for backup only. As described above, the magneto-optical disk 16 dedicated to backing up the management information is used for the autochanger device 1.
5 should be mounted on a predetermined shelf, but if the magneto-optical disk 16 dedicated to backing up the management information is not mounted on the predetermined shelf, for example, the operator is notified of the error and its content, and the management information This is dealt with by asking the operator to attach the magneto-optical disk 16 dedicated to the backup and continue the process or to interrupt the process.

Next, the contents of the management information in the H / D 18 are copied to the magneto-optical disk 16 dedicated to the backup of the management information (step S103). When the copying is completed, the date and time is written in the "update date and time" in the "volume information" of the magneto-optical disk 16 (step S104).

Then, the backed-up magneto-optical disk 16 is replaced with the disk drive 17a (or 17b).
System control unit 2 so that it can be removed from the rack and returned to the original shelf.
It is instructed to the magneto-optical disk control section 5 via the (step S105). Finally, the processing completion is displayed on the output device 12 to notify the operator (step S106).

Next, the image data backup unit 32
Original magneto-optical disk 16 ("volume information")
Of all the image data stored in the "original" flag of "the original", the magneto-optical disk 16 for backup of the magneto-optical disk 16 (the "volume ID" of the "volume information" is the original magneto-optical disk 16).
In the same manner as above, the image data is backed up by copying it to the one whose "flag" is "backup". In the image data backup unit 32, a plurality of magneto-optical disks 16 to be backed up can be designated collectively, and whether or not the designated magneto-optical disks 16 need to be backed up is checked by "update date and time". If the magneto-optical disk 16 does not need to be backed up, the magneto-optical disk 16 is not backed up.

That is, in one backup process, one magneto-optical disk is used as a unit to back up only the necessary magneto-optical disk 16 among the image data of a plurality of designated magneto-optical disks 16. is there. This is because in the management system as described above, image data of a specific work is stored for each magneto-optical disk 16, so it is convenient to perform backup for each work. For example, when one task is completed,
The image data belonging to the work can be collectively backed up, and the operation of the operator is simplified as compared with the case where the backup is performed while instructing once for each file. Moreover, since copying between the magneto-optical disks 16 can be automatically performed in the autochanger device 15, during that time, another process (another application program or the like) under the control of the system control unit 2 is performed in the process control unit 1. Can be executed, and the processing can be performed efficiently. Further, since the magneto-optical disk 16 that does not need to be backed up is not backed up, useless backup processing can be omitted and the backup processing time can be shortened.

Before the operator starts the backup processing of the image data by the processing selecting section 30, the operator automatically designates the original and backup of the magneto-optical disk 16 to be designated as the magneto-optical disk 16 to be backed up. It is confirmed whether or not the magneto-optical disk 16 is mounted on a predetermined shelf in the device 15, and if not, those magneto-optical disks 16 are mounted on the predetermined shelf. This predetermined shelf is a predetermined shelf number for each magneto-optical disk 16, and each magneto-optical disk 16 is usually mounted on the shelf.

The procedure for backing up image data will be described with reference to the flowchart shown in FIG. First, check whether other application programs are running in the device, and if they are running, wait for the processing to finish, and if other processing is not running, perform backup processing. Execute (step S20)
1). This is an autochanger device 1 by another process.
This is for the purpose of avoiding the interference of the operation of item 5.

Next, the output device 1 is requested to ask the operator to specify the magneto-optical disk 16 to be backed up.
An input message or the like is displayed in 2 and the operator waits for input (step S202). The operator inserts the magneto-optical disk 16 to be backed up from the input device 11,
For example, the volume name is specified. Then, the following processing is executed based on the designated information.

Hereinafter, the processes of steps S203 to S210 are sequentially performed for each set of the specified magneto-optical disks 16 (for each original and backup magneto-optical disks 16 of each volume name).

The magneto-optical disk controller 5 is instructed to mount the original magneto-optical disk 16 on the disk drive 17a, for example, through the system controller 2 (step S203). As a result, the magneto-optical disk control unit 5 drives the autochanger device 15 so that the original magneto-optical disk 16 is replaced by the magneto-optical disk 1.
6 is moved to the disk drive 17a from the shelf on which it is mounted, and it is checked whether or not the correct magneto-optical disk 16 is mounted on the shelf, as in the above-mentioned management information backup processing procedure (step S102) (“volume Check "ID" and "flag"), and if not attached, execute error processing similar to the management information backup processing procedure.

The original magneto-optical disk 16
The "update date and time" is read out from the "volume information" (step S204).

Next, the backup magneto-optical disk 16 is used.
To the disk drive 17b (the above-mentioned original magneto-optical disk 16 may be mounted on the disk drive 17b and the backup magneto-optical disk 16 may be mounted on the disk drive 17a). An instruction is given to the magneto-optical disk control unit 5 via 2 (step S205). Thereby, step S2
As with 03, the "volume name" and "flag" are checked, and if there is an error, the same error processing as in S203 is performed.

The backup magneto-optical disk 1
The "update date" is read from the "volume information" of 6 (step S206).

Next, the "update date" of the original and the backup read in steps S204 and S206 are compared (step S207). This comparison condition is the "update date and time" of the backup in step S209 described later.
It depends on the date and time you write to. For example, if the original "update date" is copied as is, if both "update date" are the same, it means that the original image data has not been updated since the previous backup. Without performing, the process proceeds to step S210. The original "update date" is
If it is newer than the "update date and time" of the backup, it means that the original image data has been updated since the previous backup was performed, and therefore the process proceeds to step S208 to perform the backup. Also, step S2
In 09, if the date and time of backup processing is written in the "update date and time", the original "update date and time"
Is older than the "update date and time" of the backup, the original image data has not been updated, so there is no need to back up. Otherwise,
Since the original image data has been updated, it is necessary to back up.

This relationship will be described with reference to FIG. As shown in FIG. 10, the dates T ₁ , T ₂ , T ₃ , T ₄ , T ₅
(T ₅ side is the latest), it is assumed that the “update date” between the original and the backup is T _{1 first} . Then, the original image data is updated at T ₂ ,
Considering the case of performing the backup process _3, located in the magneto-optical disk 16 backup data for backup at the time of T _1, to T ₂ of the T ₁ after,
Since the original image data has been updated, it is necessary to create backup data again. Looking at this from the update state of the "update date" between the original and the backup, in the original, from the first T _{1 in} the image data update performed in T ₂ (by another process that updates the image data) Updated to T ₂ . On the other hand, in the backup, the initial T ₁ remains. That is,
In this backup process performed at T ₃ , the “update date and time” of the original and the backup are T ₂ and T ₁ ,
The condition that needs to be backed up is T ₂ ≠ T ₁ (original “update date” ≠ backup “update date”)
It can be seen that it is.

After that, considering the case of backing up again at T ₅ , the backup data at the time of T ₂ exists in the magneto-optical disk 16 for backup (it was created at the time of T ₃ ). ), After T ₂ , the original image data has not been updated, so
At T ₅ , there is no need to create backup data again. If you look at this from the update status of the "update date" of the original and the backup, in the original,
T ₂ remains, while in the backup, in the backup processing performed to T ₃ , the first T ₁ to T 2
It has been updated to ₂ (when the original “update date” is copied). That is, in the backup process performed at T ₅ , the “update date and time” of the original and the backup are T ₂ and T ₂ , and the condition that backup is not necessary is T ₂ = T ₂ (original “update date and time = backup”). "Update date and time").

[0057] Incidentally, if made the update of the original image data to T ₄ between of T ₃ and T _5, in the same manner as described above, T
The backup at the time of ₅ is necessary, and the original "update date" at this time is updated to T ₄ , and the backup "update date" remains at T ₂ , so it is necessary to perform a backup. It can be seen that the above conditions for the case are met.

In the above description, the original "update date" is copied in updating the backup "update date", but the date when the backup was made is entered in the backup "update date". Assuming that the backup is performed in the backup process of T ₃ as described above, the “update date and time” of the backup is updated from T ₁ to T ₃ (the date and time when the backup was performed). Then, if the backup is performed at T ₅ , there is no need for the backup, as described above, and the “update date and time” of the original and the backup at this time are T ₂ and T ₃ , (the original “update date and time”) < (“Update date and time of backup”) is a condition for not performing backup.

If the original image data is updated at T ₄ , the original "update date" is updated to T ₄ , and in the backup process at T ₅ in this case,
(Original "update date and time")> (backup "update date and time"), that is, (original "update date and time")
Conditions other than <(update "update date") are conditions for backup.

Returning to FIG. 9, if the magneto-optical disk 16 needs to be backed up, the image data of the original magneto-optical disk 16 is copied to the backup magneto-optical disk 16 (step S208). Since this copying is automatically performed in the auto changer device 15, other processing can be executed in the processing control unit 1 during that time. When the copying is completed, the original update date / time or the backup (current) date / time is written in the “update date / time” in the “volume information” of the backup magneto-optical disk 16 (step S20).
9). It should be noted that, depending on which date and time is written in the "update date and time" in the "volume information", the above step S2 is performed.
Although the judgment of 07 is different, in either case, the necessity of backup can be judged as described above.

Then, the original and backup magneto-optical disks 16 are taken out from the disk drives 17a and 17b, and the magneto-optical disk control section 5 is instructed to return them to their original shelves via the system control section 2 (step S210). ). It is checked whether all the magneto-optical disks 16 to be processed are completed, and if not completed, step S203.
Then, the same backup processing is performed (step S
211). Finally, display the completion of processing on the output device 12,
Notify the operator (step S212).

In the above process, "update date and time" is used as the update information as to whether or not the backup is performed, but the present invention is not limited to this, and the original information after the previous backup is performed. Since it suffices to determine whether or not the image data has been updated, for example, an "update flag" is provided in the original "volume information", and this "update flag" is cleared (in step S209) when backup is performed ("0 If there is an update of the image data, the update flag is set (in the process) (“1” is set), and depending on whether the update flag is “0” or “1” (step S207
In this case, it may be configured to determine whether to make a backup.

Next, the management information recovery unit 33 copies the management information in the magneto-optical disk 16 dedicated to the backup of the management information whose backup data has been created by the management information backup unit 31 to the H / D 18. In this way, the management information is recovered. Before the operator starts the management information recovery process by the process selection unit 30, the operator sets the magneto-optical disk 16 dedicated to the backup of the management information to the autochanger device 1.
It is confirmed whether or not the magneto-optical disk 16 is mounted on a predetermined shelf in 5, and if not, the magneto-optical disk 16 is mounted on the predetermined shelf.

The procedure for recovering management information will be described with reference to the flowchart shown in FIG. First, it is checked whether another application program or the like is being executed in the device, and if it is being executed, wait until the processing is finished, and if another processing is not being executed,
Recovery processing is executed (step S301). This is to avoid interference of the operation of the autochanger device 15 due to other processing.

Next, the magneto-optical disk control unit 5 is instructed via the system control unit 2 to mount the magneto-optical disk 16 dedicated to the backup of the management information in the predetermined disk drive 17a (or 17b) ( Step S3
02). As a result, the magneto-optical disk control unit 5 drives the autochanger device 15 so that the magneto-optical disk 16 dedicated to backing up the management information is removed from the shelf (for example, shelf number 1) on which the magneto-optical disk 16 is mounted. It is moved to the disk drive 17a (or 17b), and the above-mentioned management information backup processing procedure (step S1
Similarly to step 02), it is checked whether or not the correct magneto-optical disk 16 is mounted on the shelf, and if it is not mounted, error processing similar to the management information backup processing procedure is executed.

Next, the contents of the backup management information created in the magneto-optical disk 16 dedicated to the backup of the management information are copied to the H / D 18 (step S303). After the copying is completed, the magneto-optical disk 16 dedicated to the backup of the management information is transferred to the disk drive 17a
(Or 17b), take it back to the original shelf,
An instruction is given to the magneto-optical disk controller 5 via the system controller 2 (step S304). Finally, the processing completion is displayed on the output device 12 to notify the operator (step S
305).

Next, the image data recovery unit 34 deletes the "volume information" of the original magneto-optical disk 16 and sets the "flag" in the "volume information" of the backup magneto-optical disk 16 from "backup" to " By changing to "original", the magneto-optical disk 16 for backup is changed to the original magneto-optical disk 16 to recover the image data. That is, since the recovery is performed without copying the image data, the recovery processing time can be shortened. Further, the image data recovery unit 34 is configured so that a plurality of magneto-optical disks 16 to be recovered can be designated collectively.

Before the operator starts the recovery processing of the image data by the processing selection unit 30 described above, the operator is supposed to designate the original and backup of the magneto-optical disk 16 to be designated as the magneto-optical disk 16 to be recovered by the automatic changer. It is confirmed whether or not the magneto-optical disk 16 is mounted on a predetermined shelf in the device 15, and if not, those magneto-optical disks 16 are mounted on the predetermined shelf.

FIG. 12 shows the processing procedure of image data recovery.
It will be described according to the flowchart shown in FIG. First, it is checked whether other application programs etc. are running in the device.If they are running, wait for the processing to finish, and if other processing is not running, execute recovery processing. Execute (step S401). This is to avoid interference of the operation of the autochanger device 15 due to other processing.

Next, an input message or the like is displayed on the output device 12 so that the operator can specify the magneto-optical disk 16 to be recovered, and the operator waits for input (step S402). The operator operates the magneto-optical disk 16 to be recovered from the input device 11 by, for example,
Specify by volume name. Then, the following processing is executed based on the designated information.

Hereinafter, the processes of steps S403 to S407 are sequentially performed for each set of designated magneto-optical disks 16 (for each original and backup magneto-optical disks 16 of each volume name).

The magneto-optical disc controller 5 is instructed to mount the original magneto-optical disc 16 on the disc drive 17a, for example, through the system controller 2 (step S403). As a result, the magneto-optical disk control unit 5 drives the autochanger device 15 so that the original magneto-optical disk 16 is replaced by the magneto-optical disk 1.
6 is moved to the disk drive 17a from the shelf on which it is mounted, and it is checked whether or not the correct magneto-optical disk 16 is mounted on the shelf, as in the above-mentioned management information backup processing procedure (step S102) (“volume Check "ID" and "flag"), and if not attached, execute error processing similar to the management information backup processing procedure.

Then, the original magneto-optical disk 16
The "volume information" of the item (step S40)
4). This is because the backup magneto-optical disk 16 is changed to the original magneto-optical disk 16 as described later, so that the original original magneto-optical disk 16 needs to be invalidated. Since it was determined that the recovery was necessary, the original contents of the original magneto-optical disk 16 were destroyed, and there is no particular problem even if it is invalidated in this way.

Next, the backup magneto-optical disk 16
To the disk drive 17b (the above-mentioned original magneto-optical disk 16 may be mounted on the disk drive 17b and the backup magneto-optical disk 16 may be mounted on the disk drive 17a). An instruction is given to the magneto-optical disk control unit 5 via 2 (step S405). As a result, step S4
As with 03, the "volume name" and "flag" are checked, and if there is an error, the same error processing as in S403 is performed.

Then, the backup magneto-optical disk 1
The "flag" in "volume information" of No. 6 is changed from "backup" to "original" (step S40).
6). As a result, the backup magneto-optical disk 16
Can be used as the original magneto-optical disk 16 thereafter.

The original original and original backup magneto-optical disk 16 (invalidated magneto-optical disk 16
Then, the newly original magneto-optical disk 16) is taken out from the disk drives 17a and 17b, and the newly original magneto-optical disk 16 is attached to the shelf on which the original original magneto-optical disk 16 is mounted. , And instructs the magneto-optical disc control unit 5 via the system control unit 2 to return the invalidated magneto-optical disc 16 to the shelf on which the original backup magneto-optical disc 16 was mounted (step S407). ). It is checked whether all the magneto-optical disks 16 to be processed are completed. If not completed, the process returns to step S403, and the same recovery process is performed (step S408). Finally, the processing completion is displayed on the output device 12 to notify the operator (step S409).

Next, the consistency check unit 35 determines the "file information" FI of each management information after the recovery of the management information or the recovery processing of the image data.
The consistency is checked to see if there is a one-to-one correspondence between the image data and the image data. This is because the management information and the image data are backed up and recovered independently, and the recovery level due to the recovery may differ due to the difference in the frequency of each backup, etc. This is because the correspondence is not always maintained. Therefore, the consistency check unit 35 checks the consistency, and when the consistency is not satisfied, the consistency repair unit 36 described later is activated to perform the repair processing. The consistency check unit 35 can specify a plurality of magneto-optical disks 16 and collectively check the consistency. This is because it is possible to recover the image data collectively as described above.

The operator selects the magneto-optical disk 16 to be designated as the magneto-optical disk 16 to be checked for consistency before starting the consistency check processing by the above-mentioned processing selecting section 30. Of the magneto-optical disk 16 is mounted on the predetermined shelf.

The processing procedure for checking the consistency will be described with reference to the flowchart shown in FIG. First, check whether other application programs, etc. are running in the device, and if they are running, wait for the processing to finish, and if other processing is not running, check consistency. The process is executed (step S501). This is to avoid interference of the operation of the autochanger device 15 due to other processing.

Next, an input message or the like is displayed on the output device 12 so that the operator may designate the magneto-optical disk 16 for checking the consistency, and the operator waits for input (step S502). The operator inserts the magneto-optical disk 16 for checking the consistency into the input device 11
For example, the volume name is specified. Then, the following processing is executed based on the designated information.

Hereinafter, the processes of steps S503 to S510 are sequentially performed for each designated magneto-optical disk. The magneto-optical disk controller 5 is instructed to mount the designated magneto-optical disk 16 on the disk drive 17a (or 17b) via the system controller 2 (step S503). As a result, the magneto-optical disc controller 5 drives the autochanger device 15 to move the magneto-optical disc 16 from the shelf on which the magneto-optical disc 16 is mounted to the disc drive 17a (or 17b), Similar to the management information backup processing procedure (step S102), whether or not the correct magneto-optical disk 16 is mounted on the shelf is checked, and if not, the same management information backup processing procedure is performed. Perform error handling.

Then, all the "file IDs" in the "volume information" of the magneto-optical disk 16 are taken out (step S504). Next, the magneto-optical disk 16
All "file information" having the "volume ID" of are extracted from the management information (step S505).

Next, the “file ID” in the retrieved “file information” is searched in sequence for the “file ID” retrieved from the magneto-optical disc 16 to obtain the “file ID” retrieved from the magneto-optical disc 16. The "file ID" that exists and is not present in the "file ID" in the retrieved "file information" is searched, and if there is a corresponding one, the restoration type is set to "registered" and the found "file ID" is set to the CPU. It is stored in the memory 19 (step S506). The repair type is information for notifying the consistency repair unit 36 of the type of repair to be performed by the consistency repair unit 36 when the consistency repair unit 36 described later is activated.

This check will be described with reference to FIG. As shown in FIG. 14, the image data “File I
“File ID” (“1”, “2”, of the management information corresponding to D ”(“ 1 ”,“ 2 ”,“ 3 ”,“ 4 ”,“ 6 ”))
When searching for “3”, “5”, “7”), there is no “file ID” “4”, “6” of the image data corresponding to the “file ID” of the management information. As described above, when the image data exists in the “file ID” of the image data but not in the “file ID” of the management information, the image data of the “file ID” (“4”, “6”) is However, the inconvenience occurs that even if the image data is valid, it cannot be searched.

Next, conversely to step S506, the "file ID" retrieved from the magneto-optical disc 16 is sequentially searched for the "file ID" in the retrieved "file information", and the retrieved "file information" is searched. “File ID” in “” and not in “File ID” extracted from the magneto-optical disk 16 is searched for, and if there is a corresponding one, the repair type is “Deleted”
And add the found "file ID" to CPU memory 1
9 (step S507).

This check will be described with reference to FIG. 14. As shown in FIG.
“File ID” (“1”, “2”, of the image data corresponding to (“1”, “2”, “3”, “5”, “7”))
When searching for “3”, “4”, “6”), there is no management information “file ID” “5”, “7” corresponding to the image data “file ID”. As described above, when the “file ID” of the management information exists but does not exist in the “file ID” of the image data, the “file ID” (“5” or “7”) is searched for in the management information. Although possible, there is a problem that the corresponding image data does not exist.

Next, the magneto-optical disk control unit 5 is instructed via the system control unit 2 to take out the magneto-optical disk 16 from the disk drive 17a (or 17b) and return it to the original shelf (step S508). . Then, it is checked whether the restoration type is “registered” or “deleted” (step S509). If either “registered” or “deleted” is present, the consistency restoration unit 36 Is activated (step S510). It is checked whether all the magneto-optical disks 16 to be processed are completed. If not completed, the process returns to step S503, and the same consistency check process is performed (step S511). Finally, the processing completion is displayed on the output device 12 to notify the operator (step S5).
12).

In the processing of the above-described consistency check unit 35, the consistency restoration unit 36 is configured to be started each time the check of one magneto-optical disk is completed.
For example, after step S511 in the above process,
The integrity repair unit 36 is provided to activate the all-optical magnetic disk 16
After the consistency check is completed, it may be configured to be collectively repaired. Similarly, in step S50
In each of the processings 6 and 507, the consistency restoration unit 36 may be activated each time data having inconsistency is found, and the consistency may be restored.

Next, the consistency restoration unit 36 operates the management information on the inconvenience found as a result of the check by the above-mentioned consistency check unit 35,
It is to be restored. As described above, the consistency restoration unit 36 is activated by the consistency check unit 35, and when the processing is completed, the consistency check unit 35 (step S51 is executed again).
Return to 1).

The processing procedure of the consistency restoration will be described with reference to the flowchart shown in FIG. First, if there is "registration" in the restoration type, the process proceeds to step S602 to execute the following management information registration process, and if there is no "registration", the management information registration process is not executed and the process proceeds to step S605. The process proceeds (step S601).

From the CPU memory 19, the above-mentioned step S
“File I” that exists in the “file ID” extracted from the magneto-optical disk 16 stored in 506 and does not exist in the “file ID” in the extracted “file information”
"D" is read out and the content is displayed on the output device 12,
Notify the operator and wait for instructions from the operator. (Step S602).

The operator determines whether or not to register in the management information (whether or not the image data is valid) based on the contents of the notification, and instructs from the input device 11 whether or not to register. The image data to be registered can be designated for each "file ID". If there is something to be registered according to the input result, the process proceeds to step S604 below, and if there is nothing to register, step S60.
It progresses to 5 (step S603). Image data not registered in the management information is preferably deleted separately by an application program or the like that deletes the image data.

In step S604, "file information" of the image data to be registered is created. "File information"
Is input by the operator from the input device 11,
It is created under a predetermined "file" of management information. Further, each data in the “file information” is created as follows, for example. "Registration date" uses the repaired date,
For the “volume position”, a fixed shelf number is set on the magneto-optical disk 16, and the “volume ID” and “file I” are set.
"D" and "file size" respectively inherit the data of "volume information" of the magneto-optical disk 16. In addition,
The "file size" is calculated from the "storage location" of the corresponding "file ID" (start address, chain information of stored sectors, final address of final address, etc.). Then, the “attribute” is created by an operator's instruction.

In step S605, if the repair type is "deleted", the process proceeds to step S606 to execute the following management information deletion process. If "deleted" is not executed, the management information deletion process is executed. Without consistency check section 3
Return to 5.

Next, from the CPU memory 19, the "file ID" in the "file information" extracted in the above-mentioned "file information" stored in step S507 and not in the "file ID" extracted from the magneto-optical disk 16 is not included. I
"D" is read out and the content is displayed on the output device 12,
Notify the operator and wait for instructions from the operator. (Step S606).

The operator determines from the management information whether or not to delete from the management information, and instructs from the input device 11 whether or not to delete. The items to be deleted can be designated for each "file ID". If there is something to be deleted according to the input result, the process proceeds to step S608 below, and if there is nothing to delete,
It returns to the consistency check unit 35 (step S60).
7). "File ID" that is not deleted from the management information
With respect to, it is preferable to separately register the corresponding image data by an application program or the like that registers the image data.

In step S608, the "file information" of the "file ID" to be deleted is deleted from the management information. When the deletion is completed, the consistency check unit 35 returns.

The image data filing apparatus can be used more efficiently by activating each of the above-described processes as follows, for example. First, regarding backup, management information having a relatively high update frequency is frequently backed up, and image data is backed up collectively in predetermined work units. This allows
Backup work can be performed as needed.

When a failure occurs, it is possible to specify only the items that need to be restored and perform the restoration work. That is, whether the information that needs to be recovered is management information (for example, destruction of the H / D 18) or image data (for example, the magneto-optical disk 16 is damaged or dirty),
If it is image data, the operator judges which magneto-optical disk 16 it is, and based on that judgment, the management information recovery unit 33 (only by specifying the magneto-optical disk 16 that needs to be recovered) Optimal recovery can be performed by individually activating the image data recovery unit 34. Moreover, in the recovery of the image data, the magneto-optical disk 1 is rewritten by rewriting the volume information of the backup magneto-optical disk 16.
Since 6 is used as the original and the data copying process is not performed, the processing time can be shortened.

Further, after the recovery process, the consistency check and the consistency restoration process always guarantee the consistency between the management information and the image data. Moreover, since the consistency check can be activated even after the recovery, the consistency check can be activated at any time and the consistency can be adjusted.

In the above-described embodiment, when the image data is backed up, it is checked whether or not it is backed up based on the "update date" and the like, and the magneto-optical disk 16 that does not need to be backed up is backed up. However, as shown in the flowchart of FIG. 16, for example, even if the check for whether or not to back up is removed and all of the specified magneto-optical disks 16 are backed up, Since the check and the consistency restoration process are provided, the consistency between the management information and the image data after the recovery can be guaranteed.

In the above embodiment, the magneto-optical disk 1 is used in the image data backup and recovery processing.
Although the configuration is performed on a sheet-by-sheet basis, the integrity check and the integrity restoration processing may be applied even for file-based backup and recovery as long as the integrity after recovery is guaranteed.

[0103]

As is apparent from the above description, according to the first aspect of the invention, the management information and the image data can be backed up independently, so that they are backed up according to the update frequency of each data. It becomes possible to do. In addition, even if each data is backed up independently in this way, consistency check means and consistency restoration means are provided, and after the recovery of management information or recovery of image data, consistency is restored. If any data that does not match the consistency is found, it is configured to match the consistency by registering or deleting the search data in the management information. And the image data can be consistently matched.

According to the second aspect of the invention, update information is provided, and only the image data that has been updated after the previous backup was performed based on the update information is backed up. Since it is configured, it is not necessary to perform unnecessary backup, and the backup processing time can be shortened.
