[0047] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0048] Electronic archives are a collection of information records in various forms such as text, graphics, audio and video, and data that are created, processed, transmitted, and stored by government agencies, groups, enterprises, institutions, other organizations, and individuals in the process of performing their statutory duties or handling affairs through computers and other electronic devices. They have preservation value, and their information security occupies a pivotal position.

[0049] In order to ensure the long-term effective reading and safe use of electronic files, electronic files must be backed up. The traditional electronic file backup method does not consider its own security level. All electronic files are backed up in the same way: they are all stored and backed up locally. This backup method cannot preserve the electronic files when an accident occurs locally.

[0050] Based on this, the embodiments of the present application provide a system, method, electronic device and storage medium for backing up an electronic file, which are described below through embodiments.

[0051] Figure 1A schematic flow chart of a method for backing up an electronic file provided in an embodiment of the present application is shown, wherein the method includes steps S101-S104; specifically:

[0052] S101, when the electronic archive management system obtains the archive to be stored, the security level of the archive to be stored is determined according to the source system of the archive to be stored;

[0053] S102, determining a target backup mode of the archive to be stored from the backup modes to be selected according to the security level of the archive to be stored; wherein the backup modes to be selected include level 1 local backup, level 2 local backup and level 3 off-site backup;

[0054] S103, backing up the archive to be stored using the target backup method to obtain a target backup archive of the archive to be stored;

[0055] S104: When the file to be stored is abnormal, the target backup file is used to replace the file to be stored.

[0056] This application matches the corresponding target backup method for the archive to be stored according to the security level of the archive to be stored, and the target backup method includes multiple methods, which can achieve the confidentiality of the electronic archive backup data.

[0057] Some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0058] The electronic file backup method in the embodiment of the present application is used for Figure 2 The electronic archive management system shown includes multiple electronic archive servers and storage disks. The local and remote in the embodiment of the present application are relative to the electronic archive management system, that is, the local representation is relatively close to the electronic archive management system in physical address (equal to or less than a preset distance threshold, for example, the distance threshold is set to ten kilometers), and the remote representation is relatively far from the electronic archive management system in physical address (greater than the preset distance threshold). The electronic archive management system is connected to the production system of each electronic archive, that is, after the production system generates the electronic archive, it sends the electronic archive to the electronic archive management system for storage (for the convenience of describing the embodiment of the present application, the electronic archive obtained by the electronic archive management system is referred to as the archive to be stored). In actual business work, the type of electronic archives produced by each production system is the same, that is, the security level of the electronic archives produced by each production system is also the same. The security level of the electronic archive is determined by the production system.

[0059] The execution subject of the method for backing up electronic archives in the embodiment of the present application is a data backup management system, which includes a backup management server, multiple backup media servers, storage disks, storage tapes, etc.

[0060] After the data backup management system detects that the electronic archive management system has received a new electronic archive (archive to be stored) produced by the production system, it determines the security level of the archive to be stored according to the security level of the production system corresponding to the archive to be stored. The security level of the production system is determined according to the specific business of the generation system. If the security level of the business is higher, the security level of the production system is higher, and then the security level of the archive to be stored produced by it is higher. For example, for a certain school, the security level of the student's personal information archive is higher than that of the physical examination information archive, and the security level of the physical examination information archive is higher than that of the grade information archive, etc. In specific implementation, the security level of the archive to be stored can be divided into low level, medium level and high level.

[0061] After determining the security level of the archives to be stored, the embodiment of the present application also needs to match the corresponding target storage method according to the security level of each archive to be stored. When matching, the embodiment of the present application selects from the candidate backup methods according to the security level. The candidate backup methods include level one local backup, level two local backup and level three off-site backup. Specifically, when the security level of the archives to be stored is low, the level one local backup is used as the target backup method; when the security level of the archives to be stored is medium, the level one local backup and the level two local backup are used as the target backup method; when the security level of the archives to be stored is high, the level one local backup, the level two local backup and the level three off-site backup method are used as the target backup method.

[0062] After matching the corresponding target backup mode for the document to be stored, the target backup mode is used to back it up. Specifically, when the first-level local backup is used as the target backup mode, the target backup mode is used to back up the archive to be stored to obtain the target backup archive of the archive to be stored, including: generating a first backup strategy according to the production process of the electronic archive management system; and backing up the archive to be stored using a local first storage medium according to the first backup strategy.

[0063] In the specific implementation, since the security level of the archives to be stored here is low, the embodiment of the present application mainly performs backup during the idle time of the electronic archive management system. That is, the first backup strategy needs to include the backup time, backup cycle and backup type, etc. The backup time here is mainly the idle time of the electronic archive management system. The first storage medium here is a disk.

[0064] When the first-level local backup and the second-level local backup are used as the target backup method, the target backup method is used to back up the archives to be stored to obtain the target backup archives of the archives to be stored, including: generating a second backup strategy according to the production process of the electronic archive management system; and according to the second backup strategy, using a local first storage medium and a local second storage medium to back up the archives to be stored.

[0065] In the specific implementation, the security of the archives to be stored here is of medium level, and two backup methods (first-level local backup and second-level local backup) are required for backup. Therefore, the generated second backup strategy needs to include two strategies: the first-level local backup strategy and the second-level local backup strategy. The first-level local backup strategy: mainly perform backup during the idle time of the electronic archive management system. That is, the first backup strategy needs to include the backup time, backup cycle and backup type, etc. The backup time here is mainly the idle time of the electronic archive management system. The first storage medium here is the disk. The second-level local backup strategy: mainly during part of the working time of the electronic archive management system, configure integrity verification and encrypted transmission in the data backup management system. After scanning, compressing, encrypting, and verifying the electronic archives during the working process of the electronic archive management system, the data transmission from the client disk storage to the data backup management system end disk storage is completed through the network to form electronic archive backup data. The second storage medium here is a tape.

[0066] When the first-level local backup, the second-level local backup and the third-level off-site backup mode are used as the target backup mode, the target backup mode is used to back up the archives to be stored to obtain the target backup archives of the archives to be stored, including: generating a third backup strategy according to the production process of the electronic archive management system; according to the third backup strategy, using a local first storage medium, a local second storage medium and an off-site second storage medium to back up the archives to be stored.

[0067] In the specific implementation, the security of the archives to be stored here is of high level, and two three-copy methods (first-level local backup, second-level local backup and third-level off-site backup) are required for backup. Therefore, the third backup strategy generated needs to include two strategies: the first-level local backup strategy, the second-level local backup strategy and the third-level off-site backup strategy. The first-level local backup strategy: mainly backup during the idle time of the electronic archive management system. That is, the first backup strategy needs to include the backup time, backup cycle and backup type, and the backup time here is mainly the idle time of the electronic archive management system. The first storage medium here is the disk. The second-level local backup strategy: mainly during part of the working time of the electronic archive management system, configure integrity verification and encrypted transmission in the data backup management system. After scanning, compressing, encrypting and verifying the electronic archives during the working process of the electronic archive management system, the data transmission from the client disk storage to the data backup management system end disk storage is completed through the network to form the electronic archive backup data. The second storage medium here is the tape. The third-level off-site backup strategy: regardless of the working time of the electronic archive management system, the backup work is given priority. Integrity verification and encrypted transmission are configured in the data backup management system. After the electronic archives are scanned, compressed, encrypted, and verified during the operation of the electronic archive management system, data is transmitted from the local disk end of the data backup management system to the off-site tape end through the network to form off-site heterogeneous backup data of the electronic archives. The second storage medium here is the tape.

[0068] After backing up the archive to be stored, in order to ensure the accuracy of the data, the embodiment of the present application will also monitor the obtained backup archive. For the convenience of description, the embodiment of the present application will use a local first storage medium, a local second storage medium and a remote second storage medium to back up the archive to be stored, and the obtained backup archives are called the first backup archive, the second backup archive and the third backup archive. The embodiment of the present application monitors the first backup archive, the second backup archive and the third backup archive. If an abnormal backup archive is found, the abnormal backup archive is maintained using a normal backup archive. If all backup archives are abnormal, the archive to be stored in the electronic archive management system is tested. After determining that the archive to be stored is tested for accuracy and completeness, the archive to be stored is backed up again. The backup process here is the same as the above-mentioned backup process, which will not be repeated here.

[0069] For example, when the first backup file is abnormal, the second backup file or the third backup file can be used to regenerate it (considering work efficiency and data security, the embodiment of the present application preferentially uses the second backup file to maintain the first backup file). When the second backup file is abnormal, the first backup file or the third backup file can be used to regenerate it (considering work efficiency and data security, the embodiment of the present application preferentially uses the first backup file to maintain the first backup file). When the third backup file is abnormal, the first backup file or the second backup file can be used to regenerate it.

[0070] After all backup work is completed, the archives to be stored in the electronic archive management system are monitored, and when the archives to be stored are abnormal, the target backup archive is used to replace the archives to be stored. The target backup archive here includes at least one of the first backup archive, the second backup archive, and the third backup archive.

[0071] If the target backup file is the first backup file, the second backup file, or the third backup file, the first backup file, the second backup file, or the third backup file can be directly used to replace it. If the target backup file includes multiple backup files, the files to be stored are replaced in the order of the first backup file, the second backup file, and the third backup file.

[0072] The method in the embodiment of the present application prolongs the life of the storage medium: the life and reliability of different storage media are different. By backing up data on multiple media, the overall storage life of the data can be extended and the risk of data loss caused by aging or damage of the storage medium can be reduced.

[0073] Reliability: Through dual backup (disk and tape), data reliability and recovery capabilities are improved. When data on the disk media is lost, the data can be restored from the tape media.

[0074] Considering both speed and capacity: The disk backup phase provides fast data backup capabilities and reduces the backup window time. The tape backup phase utilizes the high capacity of tapes to store large amounts of data.

[0075] Enhance data security: Natural disasters such as fire, flood, earthquake, etc., as well as human factors such as equipment failure and hacker attacks, can cause devastating damage to electronic files and data. Off-site heterogeneous backup can effectively reduce these risks and ensure data security by backing up data in different geographical locations and using different storage media.
