Description

Technical Field

[0001] The present invention belongs to the technical field of electronic archive storage, and in particular relates to an electronic archive backup method and system based on cloud storage. Background Art

[0002] In order to realize the backup management of electronic archives, various factors of electronic archive storage backup strategy are comprehensively considered in the invention patent publication number CN106874144 "Storage backup strategy evaluation method based on electronic archive attributes". According to the characteristics of electronic archives, multiple storage backup strategies can be evaluated, thus providing meaningful guidance and reference for archives institutions on how to choose appropriate storage media and storage backup strategies according to their own electronic archive characteristics. However, there are the following technical problems:

[0003] 1) There is no construction of the importance of electronic archives based on the confidentiality level, title, number of pages, etc. of the electronic archives. Different filing strategies are adopted based on the confidentiality level of different electronic archives, which will lead to a waste of cloud storage space and cannot guarantee the reliable storage of core important electronic archives;

[0004] 2) The use of cloud storage to automatically store electronic archives online is not considered, which affects the backup efficiency and reliability of electronic archives to a certain extent.

[0005] Based on the above technical problems, it is necessary to design an electronic file backup method and system based on cloud storage. Summary of the invention

[0006] The purpose of the present invention is to provide a method and system for backing up electronic files based on cloud storage.

[0007] In order to solve the above technical problems, the first aspect of the present invention provides an electronic archive backup method based on cloud storage, comprising:

[0008] S11 extracts the title of the electronic file, and determines the type of the electronic file based on the title of the electronic file;

[0009] S12: determining the importance of the electronic file based on the type, confidentiality level, and number of pages of the electronic file;

[0010] S13: When the importance of the electronic file is greater than the first importance threshold, proceed to step S14;

[0011] S14: Based on the confidentiality level and number of pages of the electronic file, different backup strategies are adopted to automatically back up the electronic file through cloud storage.

[0012] By analyzing the titles of electronic archives, we can get the specific types of electronic archives, such as official documents, emails, certificates, etc. On this basis, based on the type, confidentiality level and number of pages of the electronic archives, we can get the importance of the electronic archives according to the prediction model of the machine learning algorithm or the method of constructing a formula. When the importance of the electronic archive is greater than the first importance threshold, it means that the importance of the electronic archive at this time is relatively strong. Then, according to the confidentiality level and number of pages of the electronic archive, different backup strategies are adopted to automatically back up through cloud storage. For example, the more pages and the higher the confidentiality level, the full text backup is performed. The lower the number of pages and the lower the confidentiality level, the partial backup or the title backup is performed. This solves the original technical problems of not constructing the importance of electronic archives, adopting different filing strategies according to different confidentiality levels and importance, and not adopting cloud storage for automatic filing. This further improves the reliability of electronic archives, promotes the improvement of the efficiency of electronic archive backup, and reduces unnecessary waste of storage space.

[0013] By determining the importance of the electronic archive based on the type, confidentiality level and number of pages of the electronic archive, it is possible to evaluate the importance of the electronic archive from multiple angles, so that the importance can more accurately reflect the actual status of the electronic archive and lay the foundation for the automatic storage of the electronic archive.

[0014] By setting the first importance threshold, the waste of cloud storage space for electronic files with low importance is avoided, so that the cloud storage space can give priority to the storage of electronic files with high importance in a more targeted manner, thereby improving the efficiency of backup and reducing space waste.

[0015] By adopting different backup strategies based on the confidentiality level and number of pages of the electronic archives, the electronic archives are automatically backed up through cloud storage, thereby improving the efficiency of backing up the electronic archives and improving the security of the electronic archives. At the same time, the backup of the electronic archives is made more targeted, and more efficient use of storage space is achieved.

[0016] A further technical solution is that the specific steps of determining the type of the electronic archive are:

[0017] S21 extracts the title of the electronic file, and extracts keywords from the title of the electronic file to obtain keywords;

[0018] S22 matches the keyword with a keyword database based on the keyword to obtain a matching result;

[0019] S23 obtains the type of the electronic file based on the matching result.

[0020] By obtaining the types of electronic archives, the comprehensiveness of the construction of the importance of electronic archives is greatly promoted, and the foundation is laid for the final targeted backup.

[0021] A further technical solution is that the keyword database is constructed based on a mapping relationship between keywords and types of electronic archives.

[0022] A further technical solution is that the calculation formula for the importance of the electronic archive is:

[0023]

[0024] Among them, K1, K2, and K3 are constants, L, M, and Y are the weight determined according to the type of electronic file, the weight determined according to the confidentiality level of the electronic file, and the number of pages, respectively. The value range of L is between 0 and 1. The higher the importance of the type of electronic file, the larger L is. The value range of M is between 0 and 1. The higher the confidentiality level of the electronic file, the larger M is.

[0025] A further technical solution is to determine the electronic files that need to be automatically backed up by combining the confidentiality level with the importance of the electronic files. The specific steps are:

[0026] S31 determines whether the classification of the electronic file is top secret or confidential based on the classification of the electronic file. If so, the electronic file needs to be automatically backed up. If not, proceed to step S32;

[0027] S32: based on the importance of the electronic file, determining whether the importance of the electronic file is greater than a first importance threshold, if so, automatically backing up the electronic file is required, if not, proceeding to step S33;

[0028] S33: If and only if the importance of the electronic file is greater than a second importance threshold and the confidentiality level of the electronic file is confidential, it is necessary to automatically back up the electronic file, wherein the second importance threshold is less than the first importance threshold.

[0029] By determining the electronic archives that need to be automatically backed up in steps according to the confidentiality and importance of the electronic archives, the efficiency of electronic archive determination is improved, and it has higher comprehensiveness and reliability. At the same time, the automatic backup of electronic archives with low confidentiality but a certain degree of importance can ensure that electronic archives with higher importance and high confidentiality can be backed up, further ensuring the reliability of electronic archives.

[0030] A further technical solution is that the first importance threshold and the second importance threshold are determined by the number of electronic files, the space of cloud storage, and the nature of the electronic files.

[0031] A further technical solution is that the specific steps of automatically backing up the electronic archive are:

[0032] S41 determines whether the classification level of the electronic file is top secret or confidential. If so, the electronic file needs to be automatically filed in full. If not, proceed to step S42;

[0033] S42 determines whether the number of pages of the electronic file is greater than a first page number threshold. If so, the electronic file needs to be automatically filed in full. If not, proceed to step S43;

[0034] S43 determines whether the confidentiality level of the electronic file is confidential and the number of pages of the electronic file is greater than the second page number threshold. If so, the first and last pages of the electronic file are automatically filed, and the second page number threshold is less than the first page number threshold. If not, proceed to step S44.

[0035] S44 backs up the title of the electronic file.

[0036] The reliability of electronic archive backup is improved by automatically backing up the full text of the electronic archive in steps according to the confidentiality level and number of pages of the electronic archive. The top secret or confidential documents are first screened and then the number of pages is screened, so that the top secret or confidential documents with more pages are screened first, which improves the screening efficiency. The second page number threshold is set so that more content is saved in the confidentiality-level documents with a higher number of pages, which improves the reliability of the electronic archive.

[0037] A further technical solution is that the first page number threshold and the second page number threshold are determined according to the number of electronic archives and the space of cloud storage, wherein the calculation formula of the first page number threshold is:

[0038] S1=(K4(1-K5C) C +K6 arcsinD1)S

[0039] Among them, K4, K5, and K6 are constants, C, D1, and S are weights determined by the space of cloud storage, weights determined by the number of electronic files, and basic page number threshold, respectively. The value ranges of C and D are both between 0 and 1. The larger the space of cloud storage, the larger C is, and the more electronic files there are, the larger D is.

[0040] By determining the formula of the first page number threshold, the judgment of the number of pages becomes more accurate and consistent, thereby promoting the reliability of the model.

[0041] On the other hand, the present invention provides an electronic archive backup system based on cloud storage, which adopts the above-mentioned electronic archive backup method based on cloud storage, and specifically includes:

[0042] Type assessment module, importance assessment module, automatic backup module;

[0043] The type assessment module is responsible for determining the type of the electronic archive;

[0044] The importance evaluation module is responsible for determining the importance of the electronic file;

[0045] The automatic backup module is responsible for automatically backing up the electronic archives through cloud storage using different backup strategies.

[0046] On the other hand, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed in a computer, enables the computer to execute the above-mentioned electronic archive backup method based on cloud storage.

[0051] Figure 2 This is a framework diagram of an electronic archive backup system based on cloud storage in Example 2. DETAILED DESCRIPTION

[0052] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0053] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0054] Example 1

[0055] To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, a method for backing up an electronic archive based on cloud storage is provided, comprising:

[0056] S11 extracts the title of the electronic file, and determines the type of the electronic file based on the title of the electronic file;

[0057] For example, if the keywords of the title of the electronic file are "about" and "notice", then the electronic file is an official document.

[0058] S12: determining the importance of the electronic file based on the type, confidentiality level, and number of pages of the electronic file;

[0059] To give a specific example, the type, confidentiality level, and number of pages of the electronic file can be input into a prediction model based on a machine learning algorithm to obtain the importance of the electronic file. Alternatively, a specific calculation formula can be constructed through an empirical formula to convert the type and confidentiality level of the electronic file into a weight to calculate the importance of the electronic file.

[0060] S13: When the importance of the electronic file is greater than the first importance threshold, proceed to step S14;

[0061] For example, if the importance of the electronic file is 5 and the first importance threshold is 2, then the process goes to step S14, otherwise the process does not go to step S14 for automatic backup.

[0062] S14: Based on the confidentiality level and number of pages of the electronic file, different backup strategies are adopted to automatically back up the electronic file through cloud storage.

[0063] To give a specific example, when the classification of an electronic file is top secret or confidential, the full text is stored. If it is a secret or unclassified electronic file, the full text is stored only when there are many pages. Otherwise, only part of the content is saved or only the title is backed up.

[0064] By analyzing the titles of electronic archives, we can get the specific types of electronic archives, such as official documents, emails, certificates, etc. On this basis, based on the type, confidentiality level and number of pages of the electronic archives, we can get the importance of the electronic archives according to the prediction model of the machine learning algorithm or the method of constructing a formula. When the importance of the electronic archive is greater than the first importance threshold, it means that the importance of the electronic archive at this time is relatively strong. Then, according to the confidentiality level and number of pages of the electronic archive, different backup strategies are adopted to automatically back up through cloud storage. For example, the more pages and the higher the confidentiality level, the full text backup is performed. The lower the number of pages and the lower the confidentiality level, the partial backup or the title backup is performed. This solves the original technical problems of not constructing the importance of electronic archives, adopting different filing strategies according to different confidentiality levels and importance, and not adopting cloud storage for automatic filing. This further improves the reliability of electronic archives, promotes the improvement of the efficiency of electronic archive backup, and reduces unnecessary waste of storage space.

[0065] By determining the importance of the electronic archive based on the type, confidentiality level and number of pages of the electronic archive, it is possible to evaluate the importance of the electronic archive from multiple angles, so that the importance can more accurately reflect the actual status of the electronic archive and lay the foundation for the automatic storage of the electronic archive.

[0066] By setting the first importance threshold, the waste of cloud storage space for electronic files with low importance is avoided, so that the cloud storage space can give priority to the storage of electronic files with high importance in a more targeted manner, thereby improving the efficiency of backup and reducing space waste.

[0067] By adopting different backup strategies based on the confidentiality level and number of pages of the electronic archives, the electronic archives are automatically backed up through cloud storage, thereby improving the efficiency of backing up the electronic archives and improving the security of the electronic archives. At the same time, the backup of the electronic archives is made more targeted, and more efficient use of storage space is achieved.

[0068] In another possible embodiment, the specific steps of determining the type of the electronic archive are:

[0069] S21 extracts the title of the electronic file, and extracts keywords from the title of the electronic file to obtain keywords;

[0070] S22 matches the keyword with a keyword database based on the keyword to obtain a matching result;

[0071] For example, if the keywords are about, commendation, and notification, then about and notification in the keyword database correspond to official documents, and the matching result is the official document.

[0072] S23 obtains the type of the electronic file based on the matching result.

[0073] By obtaining the types of electronic archives, the comprehensiveness of the construction of the importance of electronic archives is greatly promoted, and the foundation is laid for the final targeted backup.

[0074] In another possible embodiment, the keyword database is constructed based on a mapping relationship between keywords and types of electronic archives.

[0075] In another possible embodiment, the calculation formula of the importance of the electronic file is:

[0076]

[0077] Among them, K1, K2, and K3 are constants, L, M, and Y are the weight determined according to the type of electronic file, the weight determined according to the confidentiality level of the electronic file, and the number of pages, respectively. The value range of L is between 0 and 1. The higher the importance of the type of electronic file, the larger L is. The value range of M is between 0 and 1. The higher the confidentiality level of the electronic file, the larger M is.

[0078] In another possible embodiment, the electronic files that need to be automatically backed up are determined by combining the confidentiality level with the importance of the electronic files, and the specific steps are as follows:

[0079] S31 determines whether the classification of the electronic file is top secret or confidential based on the classification of the electronic file. If so, the electronic file needs to be automatically backed up. If not, proceed to step S32;

[0080] S32: based on the importance of the electronic file, determining whether the importance of the electronic file is greater than a first importance threshold, if so, automatically backing up the electronic file is required, if not, proceeding to step S33;

[0081] S33: If and only if the importance of the electronic file is greater than a second importance threshold and the confidentiality level of the electronic file is confidential, it is necessary to automatically back up the electronic file, wherein the second importance threshold is less than the first importance threshold.

[0082] By determining the electronic archives that need to be automatically backed up in steps according to the confidentiality and importance of the electronic archives, the efficiency of electronic archive determination is improved, and it has higher comprehensiveness and reliability. At the same time, the automatic backup of electronic archives with low confidentiality but a certain degree of importance can ensure that electronic archives with higher importance and high confidentiality can be backed up, further ensuring the reliability of electronic archives.

[0083] In another possible embodiment, the first importance threshold and the second importance threshold are determined by the number of electronic archives, the space of cloud storage, and the nature of the electronic archives.

[0084] In another possible embodiment, the specific steps of automatically backing up the electronic file are:

[0085] S41 determines whether the classification level of the electronic file is top secret or confidential. If so, the electronic file needs to be automatically filed in full. If not, proceed to step S42;

[0086] S42 determines whether the number of pages of the electronic file is greater than a first page number threshold. If so, the electronic file needs to be automatically filed in full. If not, proceed to step S43;

[0087] S43 determines whether the confidentiality level of the electronic file is confidential and the number of pages of the electronic file is greater than the second page number threshold. If so, the first and last pages of the electronic file are automatically filed, and the second page number threshold is less than the first page number threshold. If not, proceed to step S44.

[0088] S44 backs up the title of the electronic file.

[0089] The reliability of electronic archive backup is improved by automatically backing up the full text of the electronic archive in steps according to the confidentiality level and number of pages of the electronic archive. The top secret or confidential documents are first screened and then the number of pages is screened, so that the top secret or confidential documents with more pages are screened first, which improves the screening efficiency. The second page number threshold is set so that more content is saved in the confidentiality-level documents with a higher number of pages, which improves the reliability of the electronic archive.

[0090] In another possible embodiment, the first page number threshold and the second page number threshold are determined according to the number of electronic archives and the space of cloud storage, wherein the calculation formula of the first page number threshold is:

[0091] S1=(K4(1-K5C) C +K6 arcsinD1)S

[0092] Among them, K4, K5, and K6 are constants, C, D1, and S are weights determined by the space of cloud storage, weights determined by the number of electronic files, and basic page number threshold, respectively. The value ranges of C and D are both between 0 and 1. The larger the space of cloud storage, the larger C is, and the more electronic files there are, the larger D is.

[0093] By determining the formula of the first page number threshold, the judgment of the number of pages becomes more accurate and consistent, thereby promoting the reliability of the model.
