[0083] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0084] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0085] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0086] The embodiment of the present application provides a data backup method. In the existing data backup methods, the system usually automatically performs the backup operation, or manually copies and pastes the data to be backed up into the target database. Regardless of the above method, due to loopholes in the system used to perform the backup operation or negligence of the backup personnel, it is easy to miss the data to be backed up or make a copy error, etc., making it difficult to ensure the backup quality of the data, resulting in data loss.

[0087] In order to overcome the above defects, the present application embodiment provides a data backup method, such as Figure 1 As shown, the backup method includes:

[0088] S101. After receiving a data backup instruction, obtain backup location information and backup range information.

[0089] Among them, the data backup instruction can be automatically triggered by a device, software or program such as a timer, or it can be received by a human-computer interaction device or a mouth interface. In one embodiment, the data in the system is backed up periodically by a timer, and the data that needs to be backed up is called data to be backed up. When the preset time of the timer is reached, the counter directly generates a data backup instruction, or triggers other instruction generation entities to generate data backup instructions, and transmits the data backup instructions to the current execution entity. It should be noted that other instruction generation entities can be programs, software, chips or devices with the function of generating instructions; the current execution entity can be an MCU, an integrated chip, an intelligent terminal, a server, etc.

[0090] In addition, in another embodiment, a timer is integrated in the current execution subject, and after a preset time is reached, a data backup instruction is generated, at which time the current execution subject determines that the data backup instruction has been received.

[0091] In other embodiments, the data backup instruction is received by the human-computer interaction device and transmitted to the current execution subject; or the data backup instruction is received through the functional interface and then obtained by the current execution subject.

[0092] The backup location information is used to describe the target location for performing the backup action, that is, the location of the data to be backed up. For example, if the data to be backed up is located in a database, the backup location information is used to describe the location of the database; if the data to be backed up is located in a certain path, the backup location information is used to describe the path; if the backup data is located in a certain application software, the backup location information is used to describe the location of the application software.

[0093] The backup range information is used to describe the range of the data to be backed up in the target location. In one embodiment, the backup range information is the same as the backup location information, that is, the data to be backed up that needs to be backed up refers to the data in the entire database, the entire table, or the entire folder. In this case, the backup location information is the same as the backup range information. In another embodiment, the backup range information represents part of the location information in the backup location information; for example, several data tables in a database, one or more sheet pages in a table, or certain rows in a document.

[0094] S102: Generate a to-be-backed-up list based on the backup location information and the backup range information.

[0095] The specific location of the data to be backed up and the data to be backed up itself can be locked through the backup location information and the backup range information. In one embodiment, after the specific location of the data to be backed up is locked, a list to be backed up can be generated by retrieving relevant information. For example, in an application scenario, the data to be backed up is the first 10 data tables in database A. The backup location information is used to describe the location information of database A, and the backup range information is used to describe the location information of the first 10 data tables. After locking the first 10 data tables in database A, the relevant information of the first 10 data tables can be extracted under the preset path to generate a list to be backed up.

[0096] In addition, the backup list is used to record the information of the data to be backed up, so as to be able to check the backup status through the backup list and find errors in the backup. Therefore, the backup list may include some data in the data to be backed up, and may include basic information of the data to be backed up.

[0097] S103: Back up the data to be backed up to the target database, forming backed up data in the target database.

[0098] The data to be backed up is backed up by a backup tool, which may be a DBFen backup platform, a Windows built-in backup program, an application system's own backup tool (eg, SQL Server / Oracle), a backup system, or the like.

[0099] S104: Generate a backed-up list based on the backed-up data, and compare the list to be backed up with the backed-up list to generate a comparison result.

[0100] According to the principle of generating the list to be backed up, a backed up list is generated based on the backed up data to obtain relevant information about the backed up data. Then, the backed up list is compared with the list to be backed up to find out whether there are omissions or errors in the backed up data. The comparison results are convenient for relevant personnel to know the backup situation, or for the current execution entity to know the backup situation. According to the comparison results, the data to be backed up is subsequently processed to improve the backed up data and the backup quality of the data.

[0101] Generating a backup list to verify the actual situation of the backup helps to detect backup errors in a timely manner so that remediation can be carried out, reducing the risk of data loss and improving the quality of data backup.

[0102] In order to improve the accuracy of verifying the true status of the backup, in another embodiment of the present application, Figure 2 As shown, the steps of generating a list to be backed up based on the backup location information and the backup range information include:

[0103] S201. Determine data to be backed up according to backup location information and backup range information.

[0104] S202: Obtain first data information of data to be backed up.

[0105] Among them, the first data information includes first name information, first data volume information and first data type. It should be noted that the first data information refers to the basic information of the data to be backed up, and the first is used to distinguish the name of the technical feature, and has no other restrictive effect. The first name information is used to describe the name of the data to be backed up, wherein, in one application scenario, the data to be backed up are the first 10 data tables in database A, then the first name information includes the table names of the first 10 data tables; in another application scenario, the data to be backed up are the third, fifth and tenth sheet pages in the Excel table, then the first name information includes the page names of the third, fifth and tenth sheet pages; in another application scenario, the data to be backed up are all folders on the disk, then the first name information includes the folder names of all folders on the disk.

[0106] The first data volume information is used to describe the data volume information of the data to be backed up. In one embodiment, the first data volume information is the space occupied by the data to be backed up; in another embodiment, the first data volume information is the number of rows and columns of the data to be backed up. For ease of understanding, for example, in one embodiment, the data to be backed up is the first to 100th rows in the first sheet of an Excel table; then the first data volume information includes the number of rows and the maximum number of columns in all rows. In addition, the first data volume information can also be the number of rows and the number of columns corresponding to each row.

[0107] In another embodiment, the data to be backed up is the first 10 data tables in database A, and the first data volume information includes the total number of rows and columns of each of the first 10 data tables. It should be noted that when the data to be backed up includes the number of rows and columns, each row and column is recorded separately.

[0108] S203: Extract characteristic data from the data to be backed up.

[0109] The characteristic data is associated with characteristic position information. It should be noted that the characteristic data is any data in the data to be backed up. That is, the data to be backed up includes a number of characteristic data. When extracting the characteristic data, the data in the data to be backed up can be extracted according to a preset extraction position to form the characteristic data; or the data in the data to be backed up can be randomly extracted to form the characteristic data, and then the characteristic position information of the characteristic data is recorded.

[0110] S204: Integrate the first data information, the characteristic data and the characteristic location information to obtain a list to be backed up.

[0111] In one embodiment, the first data information, characteristic data and characteristic position information are recorded according to the order of traversing the data to be backed up, such as from top to bottom, from left to right, and from large to small, to generate a list to be backed up. For example, if the data to be backed up is the first 10 data tables in database A, the first data information of data tables 1 to 10 are obtained in sequence, and the characteristic data and corresponding characteristic position information extracted from the first data table are recorded after the first data information of the first data table, and so on, which will not be repeated.

[0112] The first data information includes not only the first name information, the first data type and the first data volume information, but also the characteristic data in the data to be backed up. According to the first name information, the first data type and the first data volume information, it can be determined whether there are major errors in the backed up data as a whole. Through the characteristic data and the corresponding characteristic position information, it can be determined whether there are omissions and the omission locations of the backed up data, which helps to improve the accuracy of verifying the actual situation of the backup.

[0113] In another embodiment of the present invention, in order to further define and illustrate, as Figure 3 As shown, the step of obtaining the first data information of the data to be backed up includes:

[0114] S301: Determine whether attribute path information of the data to be backed up is pre-stored.

[0115] In one embodiment, for data to be backed up of types such as data tables, when generating a data table, the basic information of the data table will be recorded in a specified file. For example, the table name, type, data description, etc. of the data table. After determining the data to be backed up based on the backup location information and the backup range information, it is equivalent to obtaining the storage location of the data to be backed up, and the attribute path information can be found based on the storage location of the data to be backed up. For example, when the data to be backed up is mysql data, the storage location of the mysql database can be obtained based on the backup location information and / or the backup range information. Then, according to the storage location, the preset association table is searched to see whether the mysql database is associated with the attribute path information for recording the basic information of the mysql database.

[0116] If not, executing step S302, identifying and extracting the first name information of the data to be backed up according to the name identifier.

[0117] The name identifier is used to identify the data name, and can be a string consisting of at least one of numbers, letters and symbols, or can be field range information used to describe the field where the name is located in the data. When the attribute path information is not pre-stored, the first name information is searched in the data to be backed up according to the name identifier.

[0118] S303: Identify and extract a first data type of the data to be backed up according to the type identifier.

[0119] The data type refers to the type of data to be backed up, such as data tables, Excel spreadsheets, text documents, word documents, etc. The type identifier can be a string consisting of at least one of numbers, letters, and symbols, or it can be field range information used to describe the field where the type is located in the data. For example, query the suffix name to determine the first data type.

[0120] S304: Identify the number of rows and columns of data to be backed up to obtain first data volume information.

[0121] It should be noted that the execution order of steps S302, S303 and S304 is not limited.

[0122] If attribute path information of the data to be backed up is stored, step S305 is executed to obtain corresponding first data information according to the attribute path information.

[0123] That is, the first data information of the data to be backed up is retrieved under the corresponding path according to the attribute path information.

[0124] Priority is given to checking whether the first data information of the data to be backed up is pre-stored. If yes, the first data information is directly obtained, which helps to save computer resources, reduce memory usage, improve backup efficiency, and ensure the accuracy of the first data information. If no, the first data information is obtained according to the name identifier, etc., which is simple and fast, and is convenient for ensuring the integrity of the first data information.

[0125] In another embodiment of the present invention, for further definition and explanation, the step of generating a backed-up list according to the backed-up data includes:

[0126] S401: Obtain second data information of the backed-up data.

[0127] The second is only used to distinguish the name of the technical feature and has no other limiting function. The second data information includes second name information, second data volume information and second data type.

[0128] S402: extract data from the backed-up data according to the characteristic position information to obtain verification data.

[0129] That is, the verification data is data in the backed-up data, and corresponds one-to-one with the feature data according to the feature position information.

[0130] S403: Integrate the second data information, verification data and characteristic location information to obtain a backup list.

[0131] In one embodiment, the principle of the generation process of the backup list and the generation process of the to-be-backed list is the same, and no further description is given. It should be noted that the verification data is obtained based on the characteristic position information of the characteristic data. Through the above means, it is convenient to accurately find the backup error when comparing the backup list and the to-be-backed list.

[0132] In another embodiment of the present invention, for further definition and explanation, the step of comparing the to-be-backed-up list and the backed-up list to generate a comparison result includes:

[0133] S501: Determine whether the first name information matches the second name information.

[0134] In one embodiment, a match is determined when the first name information and the second name information are the same.

[0135] If the first name information matches the second name information, step S502 is executed to determine whether the second data type matches the first data type.

[0136] It should be noted that in some backup operations, the data type or data format of the data to be backed up will be changed. For example, the backed up data is actually compressed data. In this application scenario, the target data type of the backed up data is obtained first; then the second data type is compared with the target data type. If they are the same, the second data type is determined to match the first data type. In other cases where the data type or data format of the backed up data is not changed, the second data type is determined to match the first data type when it is the same.

[0137] If the first name information does not match the second name information, the comparison result indicating backup failure is generated.

[0138] If the second data type matches the first data type, step S503 is executed to determine whether the feature data corresponding to the feature position information matches the verification data.

[0139] The feature data and the verification data have the same feature location information. If the data type of the verification data is different from that of the feature data, the verification data is first converted to the same type as the feature data before comparison. It is considered a match when the feature data corresponding to all feature location information is the same as the verification data.

[0140] If the second data type does not match the first data type, a comparison result indicating a backup error is generated.

[0141] If the feature data and verification data corresponding to each feature position information match, a comparison result with correct backup is generated; otherwise, a comparison result with wrong data is generated.

[0142] By distinguishing the comparison results, the comparison results generated in different situations are different, which facilitates the pre-formulation of corresponding solutions. When a comparison result of backup failure, backup error or data error occurs, the current execution subject executes the corresponding steps according to the preset solution, remediates the backup results of the data to be backed up, improves the backed up data, and improves the backup quality.

[0143] In another embodiment of the present invention, for further definition and explanation, the backup method further includes:

[0144] S601. When the comparison result is that the data is wrong, the feature data and the verification data are compared one by one to obtain error range information.

[0145] Specifically, in one embodiment, the list to be backed up or the list that has been backed up contains at least one characteristic position information, and each characteristic position information corresponds to characteristic data and verification data. According to the order of the characteristic position information, the characteristic data and verification data corresponding to the same characteristic position information are determined as a group, and are compared one by one. When the same group of characteristic data and verification data do not match, the corresponding characteristic position information is marked or recorded until all characteristic data and verification data are compared, and the comparison is stopped. The error range information can be locked according to the marked or recorded characteristic position information. For ease of understanding, for example, there are 10 characteristic position information, corresponding to 10 groups of characteristic data and verification data. During the comparison, the third characteristic position information is marked, which means that the characteristic data of the third characteristic position information is different from the verification data. At this time, the error range information can be determined to be from the second characteristic position information to the fourth characteristic position information.

[0146] S602: Take a screenshot of the data to be backed up corresponding to the error range information to obtain image data.

[0147] The data to be backed up within the error range information is recorded in the form of a screenshot. Specifically, in one embodiment, the screenshot position is determined according to the error range information, the highest and rightmost position in the error range information is used as the first coordinate information, the lowest and leftmost position in the error range information is used as the second coordinate information, the point corresponding to the first coordinate information is used as the starting point of the screenshot, and the point corresponding to the second coordinate information is used as the end point of the screenshot, the screenshot position is determined, and the image data is obtained.

[0148] S603: Store the error range information in association with the corresponding graphic data.

[0149] Saving the backup data by taking screenshots, on the one hand, helps to back up the data normally in the future and ensures the backup efficiency; on the other hand, the backup data that cannot be backed up or has backup errors is not easily lost, which improves data security and backup quality. In addition, after the error range information is stored in association with the graphic data, it is helpful to find loopholes in the backup tool in the future, or accurately find the location of the backup data that has not been backed up normally, and then make accurate remediation.

[0150] After step S603, the backup method further includes:

[0151] S604: Use a text extraction tool to extract text information from the image data to obtain remedial data.

[0152] Automatically identify and extract text information from image data, eliminating the need for staff to manually restore the corresponding data to be backed up based on the image data.

[0153] In another embodiment of the present invention, for further definition and explanation, the backup method further includes:

[0154] S701. In the process of backing up the data to be backed up to the target database, if the data to be backed up cannot be backed up, a screenshot is taken according to a preset screenshot range to obtain retained image data.

[0155] Among them, the inability to back up includes the inability to read, parse or convert the data to be backed up, including the inability to identify the data to be backed up, the inability to convert the format or type of the data to be backed up, etc. The inability to back up also includes the inability to perform the backup operation, which may be because the data to be backed up cannot be backed up, for example, the data type of the data to be backed up does not belong to the data type that the backup tool can back up, or another example is that the backup tool has a vulnerability or failure and can no longer perform the backup operation.

[0156] S702: Skip the data to be backed up within the screenshot range and determine whether the data can be backed up.

[0157] If not, the screenshot range is expanded according to the preset range threshold to take a screenshot, and the retained image data is updated until the data to be backed up after skipping the screenshot range can be backed up, or the retained image data includes all the remaining data to be backed up.

[0158] If so, the subsequent data to be backed up is backed up according to normal backup operations.

[0159] The data to be backed up that cannot be backed up is recorded by taking screenshots, which reduces the risk of loss of the data to be backed up and improves data security.

[0160] Before the backup operation is performed, a list to be backed up is generated based on the data to be backed up, and the list to be backed up contains feature data at random positions; after the backup is performed, a list to be backed up is generated based on the backed up data, and the list to be backed up contains verification data at the same position as the feature data. By comparing the list to be backed up with the backed up list, it is determined whether the backed up data contains missed data to be backed up or erroneous data to be backed up, so that backup errors can be discovered in a timely manner based on the comparison results and remedies can be made for erroneous data to be backed up, thereby improving the quality of data backup.

[0161] The present application also discloses a data backup system.

[0181] If the first name information does not match the second name information, generating the comparison result indicating backup failure;

[0182] If the second data type does not match the first data type, generating a comparison result that backs up an error;

[0183] If the feature data does not match the verification data, a comparison result indicating data error is generated.

[0184] Preferably, the system further comprises an error range module, which is used to compare the feature data and the verification data one by one to obtain error range information when the comparison result is that the data is wrong;
