Description

Multi-parameter computer file moving method and system

This disclosure document relates to a computer file moving method and system, and in particular to a multi-parameter computer file moving method and system.

Generally, the way to clean up the computer file system (housekeeping) is nothing more than setting a schedule to regularly filter the files in a certain directory or folder, delete the files that have not been accessed for more than a period of time, or move them (migrate) to secondary hard drive space, tape backup, etc. It is possible to use the last access time of the file as the control parameter, but it ignores other factors. Some important files (such as system files and program execution files) may be accidentally moved or deleted because the computer has not been shut down for a long time, or because the application runs only for a long period of time, which affects the operation of the computer system.

On the other hand, due to fewer factors to consider, the existing disk defragmentation (defrag) technology only involves low-level disk sector movement operations, and cannot move or reorganize files at the operating system level, which affects the storage space. The optimization effect is still limited.

In order to solve the deficiencies of the existing technology, this disclosure document provides a multi-parameter computer file moving method, which includes the following steps. Calculate a relocation score based on a plurality of attribute parameters of a computer file, wherein the attribute parameters are based on the size of the computer file, the storage space usage of the computer file storage location, the creation time of the computer file, and the last time the computer file was The time of access and the probability that the computer file is accessed are calculated. Based on the migration score and a threshold, it is determined whether to migrate the computer file.

This disclosure document provides a multi-parameter computer file moving system, including a storage unit and a processing unit. The storage unit stores a computer file. The processing unit is communicatively connected to the storage unit, and is configured to calculate a move score based on a plurality of attribute parameters of the computer file, wherein the attribute parameters are based on the size of the computer file and the storage space usage of the computer file storage location. , the creation time of the computer file, the last time the computer file was accessed, and the probability of the computer file being accessed are calculated. Based on the migration score and a threshold, it is determined whether to migrate the computer file.

It is to be understood that both the foregoing general description and the following specific description are exemplary and explanatory only and are intended to provide further explanation of the present disclosure as required.

In order to make the description of this disclosure document more detailed and complete, reference may be made to the attached drawings and the various embodiments described below. The same numbers in the drawings represent the same or similar components.

Please refer to Figures 1 and 2, which are respectively a schematic diagram of a multi-parameter computer file moving system 100 and a flow chart of a multi-parameter computer file moving method 200 according to an embodiment of this disclosure document. As shown in Figure 1, the multi-parameter computer file moving system 100 includes a storage unit 110 and a processing unit 120, where the storage unit 110 stores a computer file, and the processing unit 120 is configured to execute as shown in Figure 2 Steps S201 and S202 of the parameter computer file moving method.

In some embodiments of this disclosure document, the multi-parameter computer file migration system 100 is used to manage financial information file systems, such as file servers that store customer information within banks, insurance companies, and stock exchanges.

In the financial industry, in order to meet customer needs, many financial services such as deposits, withdrawals, remittances, etc. are open year-round. The systems that provide services also continue to operate 24 hours a day. Records of transactions and other businesses are constantly accumulating. To maintain stability, the system needs to organize and reorganize the storage space regularly. At this time, it may be a non-working day, and some files may not have access records due to holidays, so they may be automatically deleted by the system.

On the other hand, the financial industry may experience a sharp increase in business volume due to special events. For example, when the government implements a bailout package, bank business volume suddenly increases. At the same time, the burden on the file system also increases, causing the system to reduce the available storage space. Looser standards will move and delete more files, causing unexpected mishandling.

Banks or enterprises often need to exchange important information with external institutions such as stock exchanges, joint credit reporting centers, etc. If this information such as customer files and transaction records are lost, they may suffer huge losses, are of high value, and the exchange operation is very complicated. It is highly time-sensitive, so how to effectively utilize limited storage space and provide file migration methods and systems with flexibility and functional expansion space is a very important issue.

In this embodiment, the multi-parameter computer file moving system 100 and the multi-parameter computer file moving method 200 help to improve the utilization efficiency of storage space and the reliability of file access in the financial information file system.

In step S201, the processing unit 120 calculates a migration score based on a plurality of attribute parameters of the computer file. In some embodiments of this disclosure document, the relocation score can be obtained by the following formula 1: [Formula 1]

Among them, Score is the transfer score, e is a natural constant, and a variable t can be obtained by the following formula 2:

Among them, a _n is these attribute parameters, p _n is a plurality of attribute weights corresponding to these attribute parameters, and m is the number of these attribute parameters considered in this calculation.

Step S201 further includes: the attribute parameters are based on the size of the computer file, the storage space usage of the computer file storage location, the creation time of the computer file, the last time the computer file was accessed, and the time when the computer file was stored. The probability of taking is calculated.

In some embodiments of this disclosure document, a ₁ can be set to the size of the computer file, a ₂ can be set to the storage space usage of the computer file storage location, and a ₃ can be set to the current time minus the creation of the computer file. Time, a ₄ can be set to the current time minus the time when the computer file was last accessed, a ₅ can be set to 1 minus the probability of the computer file being accessed, and the attribute parameters a ₁ to a ₅ are all positive numbers. .

In this way, the larger the size of the computer file, the higher the storage space usage of the computer file storage location, the longer the creation time of the computer file is from the current time, and the longer the computer file was last accessed from the current time. Or the lower the probability that the computer file is accessed, the greater the value of these attribute parameters.

According to the above formula 2, the attribute parameters a ₁ to a ₅ are multiplied by their corresponding attribute weights p ₁ to p ₅ respectively and then added together to obtain the variable t. The value of these attribute weights can be adjusted according to the user's needs for different attributes. , when the value of these attribute weights is larger and is a positive number, the corresponding attribute parameters have a higher influence on the value of variable t, and the values of attribute parameters a ₁ to a ₅ and the value of variable t are positive. Related.

Referring to the above formula 1, we can understand that when the value of the variable t is positive and larger, the value of the relocation score Score is larger and is between 0 and 1.

It can be seen from the above that the size of the computer file, the storage space usage of the computer file storage location and the migration score are positively correlated; and the creation time of the computer file, the time when the computer file was last accessed, the time when the computer file was accessed The probability is negatively correlated with the relocation score Score (based on the rule of the computer time variable, the earlier the time, the smaller its value).

It should be noted that when the user does not need to consider the factors represented by some of the attribute parameters a ₁ to a ₅ , the corresponding attribute weight can also be set to 0; and according to the user's needs, the corresponding attribute weight can be set to 0. A new attribute parameter a _n and its corresponding attribute weight p _n are added to introduce more different factors to decide whether to move the computer file and increase the flexibility of the multi-parameter computer file moving method and system.

In some embodiments of this disclosure document, when executing step S202, the processing unit 120 determines whether to move the computer file based on the migration score Score and a threshold. The threshold can be set to a number between 0 and 1, and when the migration score Score is greater than the threshold and less than 1, the computer file is moved. As for the threshold, it depends on the user's needs and the current status of the storage unit 110. For example, when the storage unit 110 has little remaining space and the user has urgent space needs, the threshold can be lowered to move more files out of the storage unit. 110.

It should be noted that the moving of the computer file can be set to move the computer file to other designated locations in the storage unit 110, other storage spaces, or directly delete it from the storage unit 110 according to the user's needs.

For example, the storage unit 110 includes at least two storage media, wherein a first storage medium is a magnetic disk (such as a solid state drive) with a faster file access speed, and a second storage medium is a disk with a relatively faster file access speed. Slow storage space (e.g. traditional hard drive). Because the first storage media file access speed is faster, it stores frequently used or important computer files of financial institutions (such as user account information, transaction information, policy contracts) to improve system operation efficiency; on the other hand, , the price per unit capacity of the first storage medium is higher than that of the second storage medium, so the second storage medium is used to store less frequently used computer files to take into account economic benefits. When the remaining space of the first storage space is reduced or insufficient, the multi-parameter computer file moving method 200 must be used to determine which computer files stored in the first storage medium should be moved to the second storage medium.

In some embodiments of this disclosure document, when it is determined that the computer file is moved in step S202, the processing unit 120 can move the computer file from the first storage medium in the storage unit 110 to the second storage medium, for example, from The solid state drive is moved to a traditional hard drive for backup. In this way, the available capacity of the first storage medium with faster access speed can be increased, and the storage space usage efficiency can be improved.

In another embodiment of this disclosure document, when step S202 determines that the computer file is to be moved, the computer file can also be directly deleted from the first storage medium.

In other embodiments of this disclosure document, when step S202 determines that the computer file is to be moved, disk reorganization can also be performed on the first storage medium to increase the continuity of the files in the first storage medium by moving the computer file.

In other embodiments of this disclosure, the computer file further includes a moveable parameter, and step S202 further includes determining not to move the computer file if the moveable parameter indicates that it is not moveable. At this time, the movable score Score can be obtained by the following formula 3: [Formula 3]

Among them, a ₀ is the removable parameter, and the default value is 0. If the computer file is a non-removable file (for example: system file, program execution file or other important file), it can be set to 1. In this way, the migration score Score of the unmovable file will be greater than 1, and it will not meet the condition that the migration score Score is greater than the threshold and less than 1, and will be moved by the processing unit 120. On the other hand, when the removable parameter a ₀ is 0, the calculation and judgment mechanism of the aforementioned embodiment can also be operated to determine whether the computer file should be moved.

It should be noted that the moveable parameter a ₀ can be set by the user, or the processing unit 120 can set the computer file that meets specific conditions before executing the multi-parameter computer file moving method. For example, you can set the removable parameter a ₀ to 1 for computer files that are known to be non-deletable, such as computer files with file extensions such as dll and exe. Then the computer file will not be moved by the multi-parameter computer file relocation method or system. It is judged that it needs to be moved.

The multi-parameter computer file relocation method and system proposed in this disclosure document has the technical characteristics of considering a variety of computer files and storage space attributes, introducing multiple factors, and then further judging whether to move the computer files. In this way, in addition to comparing In addition to having more flexibility in existing technology, it can also be applied to cleaning and moving operating system files, making storage space utilization more efficient.

Since this disclosed document has the above technical features, in some embodiments of this disclosed document, the multi-parameter computer file moving method and system are applied to a financial information file system. Users can manually set file attribute parameters, such as setting the removable parameter a ₀ to 1 for files whose file names contain specific words; or introduce other considerations, such as adding new attribute parameters to make the files in a specific folder The files are less likely to be moved, etc., in order to meet the needs of high value and high timeliness of financial information files.

Although several embodiments are described in detail above as examples, the multi-parameter computer file moving system and multi-parameter computer file moving method proposed in this disclosure document can also be implemented in other systems, hardware, software, storage media or combinations thereof. Therefore, the protection scope of this disclosure document should not be limited to the specific implementation manners described in the embodiments of this disclosure document, but shall be subject to the scope of the appended patent application.

It will be obvious to a person of ordinary skill in the technical field to which this disclosure document belongs that various modifications and changes can be made to the structure of this disclosure document without departing from the scope or spirit of this disclosure document. In view of the foregoing, the protection scope of this disclosure document also covers modifications and changes within the scope of the appended patent application.
