Description

  The present invention relates to media management of tape-shaped recording media, and more specifically, management of tape-shaped recording media in a configuration in which a backup center, a storage base for tape-shaped recording media, and a management server for media management are connected via a network. The present invention relates to a medium management method and a medium management program.

  In order to maintain data against disasters, in recent years, a plurality of backup centers have been established and remote backup centers have been provided so as to be separated from each other. This is to cope with wide-area disasters such as earthquakes and typhoons. Data backup is performed regularly or irregularly, and these are performed based on operation rules established by users who operate business.

  In the backup center, a tape library device is often used as a backup device, and a magnetic tape stored in a cartridge is often used as a backup medium. Such a magnetic tape may be placed in the tape library device even when it is not backed up, but it is ejected from the tape library device and stored in the backup center or a magnetic tape storage site different from the backup center. It may be stored at. In addition, the magnetic tape may be sent to a backup center at another site where data restoration or backup is performed.

  As described above, when the magnetic tape medium is stored for a long time or transported between the backup centers or between the backup center and the magnetic tape storage base, a failure may occur when data is read or written. For example, if the magnetic tape is kept wound for a long time, the magnetic tape stretches due to stress, or cinching occurs due to a sudden temperature change or vibration during transportation, thereby hindering normal read / write operations. It is known that such a problem can be used in a normal state by releasing the stress by rewinding the tape once.

  In addition, the obstruction of the read / write operation described above may be due to a decrease in the magnetic force of the magnetic tape. This is because the recording layer of the magnetic tape deteriorates when the frequency of use of the magnetic tape is high, or when the usage frequency is low and a long time has passed since the start of use. In such a case, it is necessary to replace the magnetic tape with a new magnetic tape (medium replacement).

  A method for automatically rewinding the cartridge tape has been proposed. In this method, a temperature sensor is provided in the magnetic tape device, and when the temperature detected by the temperature sensor is equal to or lower than a predetermined threshold temperature, the tape is wound over the entire length before the start of recording / reproducing of the cartridge tape. It corrects (Patent Document 1).

As another proposal, record the time of the previous rewind for each cassette, calculate the storage period from that time and the current time, and remove the cassette that has passed the set storage period from the storage shelf. Rewinding is performed (Patent Document 2).

  As described above, the magnetic tape used in the backup center has a problem that the read / write operation cannot be normally performed due to stress due to the storage period or transportation. In addition, there is a problem that normal read / write operation cannot be performed even when the magnetic force of the magnetic tape is reduced.

  In view of such a problem, an object of the present invention is to provide a medium management method and a medium management program for centrally managing each tape-shaped recording medium with respect to a tape-shaped recording medium including a magnetic tape used in a plurality of backup centers.

The medium management method and the medium management program of the present invention are configured as follows.
(1) 1st invention In 1st invention, the backup center which backs up data using a tape-shaped recording medium, the storage base of a tape-shaped recording medium, and the management server which manages the medium of a tape-shaped recording medium are a network. Is a medium management method for a tape rewinding of a management server in the configuration.

  FIG. 1 shows the principle of the management server medium management method, which comprises a transport stress evaluation value storing procedure 1, an operation information storing procedure 2, a warehousing information storing procedure 3, an inquiry request receiving procedure 4 and an answering procedure 5.

  In the transport stress evaluation value storage procedure 1, an evaluation value that evaluates the magnitude of the stress that the tape-shaped recording medium receives in the transport between the backup center and the storage base or between the bases of the tape-shaped recording medium between different backup centers is obtained. It memorize | stores beforehand as transport stress evaluation value DB in the memory | storage part with which a management server is provided. For example, if the tape-shaped recording medium is transported from the backup center A to the backup center B by land transportation over a long distance from the cold region, the stress applied to the tape-shaped recording medium is large, and the transport stress evaluation value is set as the transport stress. It memorize | stores in evaluation value DB. For example, the greater the stress is, the greater the transport stress evaluation value is.

  The operation information storage procedure 2 receives operation information including the tape ID of the tape-shaped recording medium used by the backup center, the base ID of the backup center, and the date of use from the backup center, and stores it in the storage unit as an operation information DB.

  The storage / retrieval storage procedure 3 receives storage information including the tape ID of the tape-shaped recording medium stored in the storage base and the base ID of the storage base from the storage base, and stores it in the operation information DB.

  The inquiry request receiving procedure 4 receives an inquiry request for necessity of tape rewinding including information on the tape ID designated from the backup center.

  Response procedure 5 refers to the transport stress evaluation value DB and the operation information DB based on the inquiry request, and the transport stress evaluation value from the nearest base of the tape-shaped recording medium to the current base for the tape ID exceeds the predetermined evaluation value. If the period from the most recent use date to the current time point exceeds the predetermined period, it is determined that the tape needs to be rewound, and the answer is sent to the backup center.

  With the above configuration, since the management server centrally manages information necessary for medium management, it is possible to respond to the processing corresponding to the tape rewinding inquiry request from the backup center.

(2) Second invention In the second invention, a backup center for backing up data using a tape-shaped recording medium, a storage base for the tape-shaped recording medium, and a management server for managing the medium of the tape-shaped recording medium are networked. Is a medium management method for medium exchange of a management server in the configuration.

  The medium management method of the second invention comprises an operation information storage procedure, an inquiry request reception procedure, and an answer procedure.

  The operation information storage procedure receives operation information from the backup center including the tape ID, new start date, read / write error retry count, and mount count for the tape-shaped recording medium used by the backup center. Store in the storage unit.

  The inquiry request receiving procedure receives an inquiry request for necessity of medium replacement including information on the tape ID designated from the backup center.

  The reply procedure refers to the operation information DB based on the inquiry request, and the medium replacement is required when the number of retries or the number of mounts of the tape-shaped recording medium for the tape ID exceeds a predetermined answer set respectively. Decide and answer to the requesting backup center. Alternatively, when the usage period from the new usage start date to the current time point exceeds the predetermined usage period, it is determined that the medium needs to be replaced, and a response is made to the backup center.

With the above configuration, since the management server centrally manages information necessary for medium management, it is possible to respond to processing corresponding to a medium replacement inquiry request from the backup center.
(3) Third invention In the third invention, a backup center for backing up data using a tape-shaped recording medium, a storage base for the tape-shaped recording medium, and a management server for managing the medium of the tape-shaped recording medium are networked. This is an invention of a medium management method performed by a computer of a backup center in a configuration in which connection is established through the network.

  FIG. 2 shows the principle of the media management method of the backup center computer. The operation information transmission procedure 10, the tape rewinding consultation request procedure 20, the medium replacement consultation request procedure 30, the response reception procedure 40, the response processing execution procedure 50, and Consists of.

  The operation information transmission procedure 10 is performed when the tape-shaped recording medium is ejected from the tape library apparatus of the backup center, the tape ID of the tape-shaped recording medium, the base ID of the backup center, the use date, the new use start date, read / write. Sends operation information including the number of retries due to errors and the number of mounts.

  In the tape rewinding inquiry request procedure 20, when a tape-shaped recording medium is inserted into the tape library apparatus, a tape rewinding inquiry request including the tape ID of the tape-shaped recording medium is transmitted to the management server.

  In the medium exchange inquiry request procedure 30, when a read / write error occurs in the tape library device, the medium exchange inquiry request procedure 30 transmits an inquiry request for necessity of medium exchange including the tape ID of the tape recording medium to the management server.

  The reply reception procedure 40 receives a reply to the consultation request from the management server.

  The corresponding process execution procedure 50 executes a process corresponding to the content of the answer on the tape-shaped recording medium having the tape ID for which the inquiry request has been made. For example, if the reply is “rewinding required” in response to the tape rewinding inquiry request, tape rewinding of the tape-shaped recording medium of the tape ID is performed. If the reply is “medium replacement required” in response to the medium replacement consultation request, the operator is notified to replace the tape recording medium of the tape ID.

With the above configuration, the backup center can know whether or not to rewind the tape or whether or not to change the medium by consulting with the management server, and can execute processing corresponding to it. In addition, since the plurality of backup centers transmit the operation information to the management server, the operation information can be centrally managed by the management server.

  According to the third invention, the backup center can consult with the management server, thereby providing a medium management method capable of reliably performing tape rewinding and medium replacement.

  According to the fourth aspect of the invention, since the management server centrally manages the information on the magnetic tape, it is possible to provide a medium management method capable of reliably performing tape rewinding and medium replacement. In addition, by consulting the management server with the backup center, it is possible to provide a medium management method that can reliably perform rewinding of the magnetic tape and medium replacement.

  According to the fifth aspect, it is possible to provide a medium management program capable of obtaining the same effect as the first aspect.

  An embodiment of a medium management system will be described with reference to FIGS.

  FIG. 3 shows an example of the configuration of the medium management system, showing only the part related to the present invention, and comprises a management server 100, a network 200, a backup center A300, a backup center B400, and a magnetic tape storage base 500. Here, a magnetic tape (hereinafter also referred to as a cartridge magnetic tape or CMT (Cartridge Magnetic Tape)) housed in a cartridge as a tape-like recording medium will be described as an example. Further, here, it is assumed that a magnetic tape library device (hereinafter also referred to as MTL (Magnetic Tape Library)) is used for backup at the backup center.

  The management server 100 includes a transport stress evaluation value DB 110 and an operation information DB 120, and responds to the requesting backup center in response to an inquiry request from the backup center A300 or the backup center B400. The network 200 is, for example, a dedicated line. The backup center A300 includes a computer 310, MTL-A320, and MTL-B330, and the backup center B400 includes a computer 410 and MTL-C420. The magnetic tape storage base 500 includes a computer 510 and a CMT (cartridge magnetic tape) 501 stored therein.

  Next, individual configurations of the management server 100, the network 200, the backup center A300, and the magnetic tape storage base 500 will be described.

  FIG. 4 shows the configuration of the management server 100. The main control unit 130 that controls the whole, the communication control unit 140 that controls communication with the network 200, and the KB (input device for registering the transport stress evaluation value) Keyboard) Input control unit 150 for controlling 151, transport system evaluation value DB 110 storing transport system evaluation values between bases, operation information DB 120 storing operation information in the backup center of each CMT, and medium loaded in main memory 160 The management program 170 is configured.

  The medium management program 170 further includes a transport stress evaluation value registration unit 171, an operation information registration unit 172, and an inquiry request processing unit 173.

  The transport stress evaluation value registration unit 171 registers (stores) the transport stress evaluation value input by the operator from the KB 151 in the transport stress evaluation value DB 120.

  The operation information registration unit 172 receives the CMT operation information transmitted from the backup center A300 or the backup center B400, and registers the information in the operation information DB 120. Alternatively, CMT input information transmitted from the storage base 500 is received, and the information is registered in the operation information DB 120.

  The advisory request processing unit 173 receives an inquiry request for necessity of tape rewinding or medium replacement transmitted from the backup center A300 or the backup center B400, and refers to the transport stress evaluation value DB 110 and the operation information DB 120. A reply to the consultation request is created according to the rules described in the consultation request processing unit 173, and the reply is sent (transmitted) to the requesting backup center.

  Next, data examples of the transportation system evaluation value DB 110 and the operation information DB 120 will be described.

  FIG. 5 shows an example of data in the transportation system evaluation value DB 110, and shows an evaluation value of stress applied to the CMT accompanying transportation between bases. The first row shows the backup center and the magnetic tape storage base, the first row shows only the backup center, and the stress evaluation value due to transportation between them is shown in each column in the table. This table is based on the backup center in the first column as a reference, and the transport stress evaluation value for the base in the first row is obtained for the backup center. Since the inquiry request is made from the backup center, the first column lists only the backup center. The higher the numerical value, the greater the stress. For example, the transport stress evaluation value between the backup center A and the magnetic tape storage base A is as high as 100, but between the backup center B and the magnetic tape storage base A. The transport stress evaluation value is as low as 20. This is because the magnetic tape storage base A is far away from the backup center A and the climatic conditions are very different, and the backup center B is relatively close and the climatic conditions are the same. .

  FIG. 6 shows an example of data in the operation information DB 120. “Tape ID” for identifying the CMT, “Tape use start date” indicating the date when the CMT was newly used, “The most recent use date” indicating the date of use of the CMT, “the most recent base ID” for identifying the backup center or the storage and storage base where the CMT is installed, and “the most recent base ID” "MTL device ID" for identifying the MTL device at the backup center when "is a backup center", "Cumulative number of retry occurrences" that is the total number of retries caused by errors at the time of reading and writing, and CMT Is composed of fields such as “total number of mounts” that is the total number of mounts in the MTL. For example, a CMT with a tape ID of 10001 is used for the first time on April 10, 2004, and most recently used on the MTL-C magnetic tape library device of the backup center B on October 15, 2006, and a retry occurs. It can be seen that the total number of times is 3, and the total number of mounts is 150. This operation information is transmitted to the management server when it is ejected from the magnetic tape library apparatus at the backup center. When the management server receives the operation information, the corresponding information is received for each field of “the most recent use date”, “the most recent base ID”, and “the MTL device ID” for the corresponding tape ID. Although the values of the “retry occurrence count cumulative” and “mount count cumulative” fields are cumulative, the received value is added to the value before the update, and the value is stored. If the tape ID of the received operation information does not exist in the operation information DB 120, it is regarded as a new CMT and a new tape ID is set, and the “tape use start date” is “the most recent use date” ”On the same date. When the warehousing information is transmitted from the magnetic tape storage base, the "MTL device ID" is set to the ID of the magnetic tape storage base that is the transmission source, with the "most recent use date" as it is. Update the field to blank.

  Next, a configuration example of the backup center will be described. FIG. 7 shows the configuration of the backup center 300, which includes a computer 310, MTL-A 320 and MTL-B 330.

  The computer 310 includes a main control unit 340 that controls the whole, a communication control unit 350 that controls communication with the network 200, an input control unit 360 that controls two magnetic tape library devices, MTL-A 320 and MTL-B 330, and It is composed of a backup center medium management program 380 loaded in the main memory 370.

  The medium management program 380 further includes an operation information transmission unit 381, an inquiry request unit 382, and an answer processing unit 383.

  When the CMT is ejected from the magnetic tape library device, the operation information transmission unit 381 uses the date and time of the retry, and the number of retries and the number of mounts after mounting in the magnetic tape library device as the operation information. Send to.

  The advisory request unit 382 issues an advisory request for necessity of rewinding the tape when the CMT is inserted into the MTL-A320 or MTL-B330, or an advisory request for necessity of medium replacement when an error occurs during reading or writing of the CMT. Transmission to the management server 100 is performed. The consultation request includes information on the tape ID of the CMT to be consulted.

  The response processing unit 383 receives a response from the management server 100 in response to the inquiry request, and executes processing for the response. For example, if the answer to the inquiry request for tape rewinding is “rewinding required”, the corresponding CMT is rewound over its entire length. Alternatively, if the answer to the inquiry request regarding whether or not to replace the medium is “medium replacement required”, the operator is notified that the medium needs to be replaced.

  The magnetic tape library device (MTL-A320, MTL-B330) has a CMT loading / unloading mechanism. When the CMT is loaded here, the hand grabs the CMT, transports it while holding the CMT, and mounts the CMT on the drive. To do. Alternatively, the CMT is stored in a rack storage shelf in the magnetic tape library apparatus. The hand is equipped with a barcode reader so that the tape ID attached to the CMT can be read when the hand grasps the CMT.

  Although the configuration of the backup center A300 has been described here, the backup center B400 has the same contents as the backup center A300 except that there is only one magnetic tape library device.

  Next, a configuration example of the magnetic tape storage base 500 will be described. FIG. 8 shows the configuration of the computer 510 of the magnetic tape storage base 500. The main control unit 520 that controls the whole, the communication control unit 530 that controls communication with the network 200, and the tape ID bar affixed to the CMT. It comprises an input / output control unit 540 that controls a barcode reader 541 that reads a code, and a medium management program 560 for a magnetic tape storage base loaded in the main memory 550.

  The medium management program 560 includes a warehousing information transmission unit 561. When the CMT is received, the warehousing information transmission unit 561 stores its own magnetic tape when the barcode attached to the CMT is read from the barcode reader 541 by the operation of the operator. The tape ID information is transmitted to the management server 100 together with the base ID of the base.

  In the above, the component which comprises a medium management system, and the outline | summary were demonstrated. Next, a flow example of medium management will be described. Here, an example in which an inquiry request is made from the backup center A 300 to the management server 100 will be described.

  FIG. 9 shows a flow example of whether or not tape rewinding is necessary. The flow of the computer 310 of the backup center A 300 is shown on the left side and the flow of the management server 100 is shown on the right side. First, the flow starts because the CMT is input to the MTL-A 320 by the operator. The MTL-A320 hand reads the barcode attached to the inserted CMT and obtains the tape ID. Then, a tape rewind necessity consultation request including the tape ID is transmitted to the management server 100 (S100, S110).

  The management server 100 receives an inquiry request from the backup center A 300 regarding whether or not to rewind the tape. Then, with reference to the operation information DB 120, information on the base where the CMT is most recently placed is acquired. Based on the acquired base information, the transport stress evaluation value DB 110 is referred to, and the transport stress evaluation value between the requesting backup center A300 and the acquired base is acquired. If the acquired transport stress evaluation value is larger than a preset evaluation value (predetermined evaluation value), it is determined that “rewinding is necessary”. For example, the predetermined evaluation value is 60 (S120-S160).

  If the acquired transport stress evaluation value is smaller than the predetermined evaluation value, the operation information DB 120 is referred to and the number of days when the CMT is not used is obtained. Non-use means that the CMT is not put into the MTL and is not used. The number of days is obtained by subtracting the most recent use date from the current date. If the number of non-use days is equal to or greater than the predetermined number of days, it is determined that “rewinding is necessary”. If it is less than the predetermined number of days, it is determined that “rewinding is unnecessary”. For example, the predetermined number of days is 90 days. The determination result is transmitted as an answer to the requesting backup center A300 (S160-S200).

  The backup center A 300 receives the response from the management server 100 and, if the response content is “rewind required”, rewinds the CMT that has requested the consultation over the entire length. If the response content is “rewinding unnecessary”, the rewinding process is not performed (S210-S230).

  Next, the flow of whether or not medium replacement is necessary will be described. FIG. 10 shows the flow of the computer 310 of the backup center A 300 on the left side and the flow of the management server 100 on the right side as in FIG. The flow starts when a read error or a write error of the CML attached to the MTL-A 320 occurs. The computer 310 of the backup center A300 receives the information on the occurrence of the retry of the MTL-A320 and transmits an inquiry request regarding the necessity of medium replacement including the tape ID of the CMT to the management server 100 (S300, S310).

  The management server 100 receives the transmitted inquiry request. Then, the cumulative number of CMT retries and the number of mounts of the tape ID included in the inquiry request is acquired with reference to the operation information DB 120. If the number of retry occurrences and the number of mounts are larger than the preset number (predetermined number), it is determined that “medium replacement is required” (S320 to S350).

  If both the number of retries and the number of mounts are smaller than the predetermined number, the operation information DB 120 is referred to, and the number of days between them is obtained by subtracting the date of starting tape use from the date of today. If the calculated number of days is equal to or greater than a predetermined number of days (predetermined number of days), it is determined that medium replacement is necessary. If the calculated number of days is smaller than the predetermined number of days, it is determined that “medium replacement is not required”. Then, the obtained determination result is transmitted as an answer to the computer 310 of the backup center A 300 as the request source (S360-S390).

  The backup center A 300 receives the response from the management server 100, and notifies the operator that the CMT needs to be replaced if the response content is “medium replacement required”. If the response content is “medium replacement unnecessary”, the notification is not performed (S400 to S420).

  The above flow is executed by the medium management programs 170 and 380.

In addition to the above embodiment, the following additional notes are disclosed.
