Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a data reduction method, a device and a medium.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
In a computer data recovery application scenario, due to a computer operation failure or a malicious attack, data in a computer system may be lost or damaged, and in this case, if only the lost or damaged data is restored, a situation that original data is not matched with the restored data or the original data has an insignificant error may occur, which affects normal operation of the system. According to the data restoration method, when a first preset condition is met (for example, a user triggers an operation of deleting target data or the target data meets a second preset condition), the target data is deleted and all data in the system to be restored are restored according to backup data, and if the first preset condition is not met, the data to be restored in the target system are directly restored. According to the scheme provided by the application, the original data in the system is deleted when the preset condition is met, so that the situation that the system cannot work normally due to the fact that the original data is wrong or the original data is not matched with the restored data is prevented. Meanwhile, when the original data are determined to have no errors, the step of deleting the target data can be skipped, and the data in the system to be restored can be directly restored, so that the data restoring process is simpler and quicker.
Fig. 1 is a flowchart of a data restoring method according to an embodiment of the present application, and as shown in fig. 1, the data restoring method includes:
s10: and acquiring the backup file and analyzing the backup file to acquire backup data.
In a specific implementation, the backup file may be stored in a local storage device, or may be stored in a cloud server. It can be understood that the former method is more convenient and reliable, is less affected by the environment, can still ensure the normal operation of the data restoration work when the computer can not be connected with the network, but needs to be configured with an additional storage device when more backup files exist, thus increasing the system cost; the latter mode can better ensure the safety of the backup files and can update the backup files in time.
It should be noted that the backup file mentioned in this application document may be a backup of all files and data in the system, and may also be a backup of data of a certain application in the system, which is not limited herein. If the backup is of a certain application, the target data and the original data mentioned in the application are only data corresponding to the application.
It can be understood that, if the backup file is stored in the remote server, the downloaded backup file needs to be checked (for example, hash check) when the backup file is acquired, so as to ensure the integrity of the backup file. The obtained backup file may be a resource package of a version specified by the user, or may be a resource package of the latest version, which is not limited herein.
S11: and judging whether the state of the system to be restored meets a first preset condition or not.
It can be understood that, since the manner of deleting the original data in the system and completely restoring needs to occupy a large amount of computing resources, the operation of completely restoring can be performed only when the files in the system meet the first preset condition. For example: when the user can not judge whether the original data has errors, the original data in the system can be deleted in a manual operation mode and all the original data are restored; or when the system detects that the original data is abnormal, deleting the original data in the system and completely restoring the original data.
In this embodiment, the method for the system to determine whether the original data is abnormal is not limited. Whether the original data is abnormal or not can be judged by judging whether the check bit or the time stamp in the original data is correct or not.
S12: and if so, determining target data according to the backup data and deleting the target data, wherein the target data is the original data in the system to be restored.
In specific implementation, if a first preset condition is met, target data corresponding to backup data in a system to be restored is determined. It can be understood that, when the failed data is system data, all the original data corresponding to the backup data are target data, and all the original data need to be deleted and restored according to the backup data. When the data with the fault is the data of a certain application, the data corresponding to the application in the backup data is preset target data, and the original data corresponding to the preset target data in the system is target data. In addition, when the user determines that the error or the abnormality of a certain part of data does not exist absolutely, the part of data can be reserved in a mode of presetting the target data by the device.
It can be understood that, in order to prevent the failure of data restoration caused by the failure of original data deletion, the system may be detected after the original data is deleted to determine whether the original data is completely deleted. If the deletion is complete, go to S13; if not, judging whether the deleting process has file deleting authority, if not, granting the file deleting authority to the deleting process and executing the deleting operation again; and if the data recovery system has the deletion authority, the data recovery system is shown to be in fault, and first early warning information is sent to a manager so that the manager can maintain the data in time.
S13: and restoring all the data of the system to be restored according to the backup data.
In specific implementation, when the data of the system to be restored is restored according to the backup data, the saving path of the file is determined according to the name space and the attribute information of the file in the backup data, and the file is created in the corresponding path.
It should be noted that it is also necessary to record whether the data is successfully restored. When data cannot be restored normally, the reason for restoration failure is first determined, and the failure reason generally includes: the file exists in the path, and the storage space under the path is insufficient. If the failure reason is that the file already exists, recording as successful restoration; otherwise, recording as failure, and sending second early warning information to the manager.
In a specific implementation, in order to prevent the multiple restoring processes from interfering with each other, only one restoring process can be allowed to operate at the same time by limiting one file through a distributed lock.
It can be understood that when the data restoring task is completed, information of the file restored in the restoring task at this time needs to be recorded in the restoring report, so as to provide data support for subsequent maintenance work on the system.
The embodiment provides a data reduction method, which comprises the following steps: acquiring a backup file and analyzing the backup file to acquire backup data so as to restore system data according to the backup data; and judging whether a first preset condition is met, if so, deleting the original data corresponding to the backup data, wherein the original data is the data in the system to be restored, so as to prevent the original data from being wrong or not matched with the restored data and influencing the normal work of the system. And restoring the data of the system to be restored according to the backup data so as to ensure that the system can work normally. Therefore, the data restoring method provided by the application can prevent the situation that the system cannot work normally due to the fact that the original data are wrong or the original data are not matched with the restored data by deleting the original data in the system when the preset condition is met.
In particular implementations, the causes of data corruption in computer systems are diverse, such as: data damage may be caused by external malicious attacks, program running errors, or data loss or damage caused by computer hardware damage. For data damage caused by different reasons, if a method of deleting target data and completely replying is adopted, waste of computing resources may be caused. Therefore, the target data is completely deleted and recreated only when the system to be restored satisfies the first preset condition. When the first preset condition is not met, it is indicated that no error occurs in the original data in the system to be restored, and only missing data in the system needs to be restored.
On the basis of the above embodiment, the first preset condition includes:
and detecting that the operation of deleting the target data triggered by the user and/or the state of the target data meet a second preset condition.
It is understood that the operation of the user triggering deletion of the target data includes clicking a delete button or inputting a delete command, and in a specific implementation, a selection page may be created in the system, and the user selects whether to delete the original data in the system to be restored. It should be noted that, in order to ensure the security of the system, a right may also be set for the user, and only the user with the corresponding right can execute the operation of deleting the original data.
In specific implementation, besides determining the reduction method according to user selection, which reduction method is adopted can be determined according to the state of the target data, for example, whether the target data in the system to be reduced has errors is detected through the check bits; or judging whether the target data is matched with the restored data according to the amount of the target data in the system to be restored or the time stamp in the data. And if the target data is wrong or the target data is not matched with the reduction data, the state of the target data meets a second preset condition, and at the moment, the target data in the system to be reduced is deleted and all data in the system are reduced.
In this embodiment, the detected deletion operation of the user and/or the detected second preset condition that the target data meets the second preset condition is used as the first preset condition, so as to ensure that the system can reduce the computing resources consumed by the system for restoring the data on the basis of successfully restoring the data.
In the specific implementation, the data that the user wants to restore may be data of the whole computer system, or data of a certain application in the system, and in addition, there may be some data that the user determines is error-free and does not need to restore. If the user cannot control the target data to be restored, the data of the whole system needs to be completely deleted and restored when the data of a single application is restored, which causes waste of computing resources.
To solve the technical problem, on the basis of the above embodiment, determining the target data according to the backup data includes:
judging whether preset target data exist in the backup data or not;
if yes, determining original data corresponding to preset target data as target data;
and if the backup data does not exist, determining all original data corresponding to the backup data as target data.
The preset target data is a part of the backup data, may be data preset by a user, or may be automatically determined by the system according to the data of the application to be restored, and is not limited herein. It should be noted that if the preset target data exists, the original data corresponding to the preset target data in the system is used as the target data; and if the target data does not exist, all the original data corresponding to the backup data in the system are used as the target data.
In this embodiment, by determining whether the preset target data exists in the backup data, the amount of the target data is further reduced, and the waste of computing resources in the data restoring process is prevented.
In the specific implementation, it needs to be ensured that the target data in the system to be restored is completely deleted, so as to prevent the restoration failure. Therefore, on the basis of the above embodiment, after the step of deleting the target data, the method further includes:
judging whether the target data is deleted or not;
if not, judging whether the process executing the deleting operation has the file deleting authority or not;
if the file does not have the deletion authority, the file deletion authority is granted to the process for executing the deletion operation;
and if the authority of deletion is available, first early warning information is sent to the manager.
And if the deletion is successful, executing the operation of restoring the data.
It can be understood that the reason for the failure of data deletion may be that the process executing the deletion operation does not have the deletion authority, and therefore, when the deletion fails, it should be first detected whether the process executing the deletion operation has the deletion authority, and if the process does not have the deletion authority, the deletion authority is granted and the deletion operation is executed again; if the system has the deletion authority, other problems exist in the system, such as: and if the process for executing the deleting operation has errors, sending first early warning information to the manager in time so that the manager can maintain the system in time.
In a specific implementation, the manner of sending the warning information may be to pop up a warning popup window in the system interface, or write a log file, and the like, which is not limited herein.
In the embodiment, whether the target data is successfully deleted is judged, so that the successful execution of the restoration operation is ensured, and the reliability of the system is improved.
In a specific implementation, the backup file may be stored in the local storage device, or may be stored in the remote server, and compared with the former method, the storage in the remote server can better ensure the security of the backup file, and is convenient for updating and maintaining. Therefore, in this embodiment, the backup file is selected to be acquired from the remote server.
On the basis of the above embodiment, acquiring the backup file includes:
judging whether a preset version of the backup file exists in a backup file library or not;
if yes, obtaining the backup file of the preset version;
and if the backup file does not exist, acquiring the backup file of the latest version.
In order to ensure the reliability of the backup file, the backup file needs to be frequently updated. In specific implementation, backup files are generated according to the original data of the system at preset time intervals and are stored in a file library of a remote server.
It will be appreciated that in order to further increase the diversity and reliability of the remote repository, the repository contains a plurality of computer system backup files that may be used alternatively.
In order to ensure that the acquired backup file can normally run on the current equipment, before the backup file is used for hilt equipment, the validity of the downloaded backup file needs to be checked, whether the backup file is complete is checked through a hash algorithm, the hash algorithm and a key are generally used for carrying out hash operation on file data to obtain a hash value of the file data when the backup file is checked, then the hash value and the data are sent to a remote server together, after the remote server receives the data, the hash operation is carried out on the data by using the same hash algorithm and key to obtain the hash value, and if the obtained hash value is the same as the received hash value, the file data is stated to be not tampered. The hash algorithm used in the network data integrity check generally includes MD5 algorithm and SHA algorithm.
Further, different devices have different hardware architectures, such as an X86 architecture, an X64 architecture, an ARM architecture, and the like, and different operating systems, such as a Windows system, a Linux system, and the like, and in order to ensure that the backup files can normally operate, it is also necessary to check whether the downloaded backup files are suitable for the current device.
In this embodiment, the reliability of the data recovery system is provided by defining the backup files to be used, preferentially using the backup files specified by the user or the latest version.
In specific implementation, data restoration is very important for normal operation of the system. If the data recovery fails, the pit can cause the operation of the system to have risks, and loss is caused. Therefore, it is necessary to determine whether data restoration is successful in time.
On the basis of the above embodiment, after the step of restoring the data of the system to be restored according to the backup data, the method further includes:
judging whether the reduction is successful;
if the data is unsuccessful, judging whether the failure reason is that the original data already exists;
and if not, sending second early warning information to the manager.
In a specific implementation, the reasons for the failure of the backup data restore include: insufficient computing resource quota, insufficient file storage space, existing original data and the like. And when the failure reason is that the original data already exists, indicating that other data recovery processes finish the operation and not needing to restore again. Otherwise, it indicates that the process executing the restore operation has an error, and needs to send early warning information to the manager in time for quick maintenance.
Furthermore, a distributed lock can be used for limiting the processes capable of simultaneously executing the restoration operation, so that the processes for executing the restoration operation are prevented from interfering with each other.
In this embodiment, whether data recovery is successful is detected, and when data recovery fails, whether a system needs to be maintained is determined according to a failure reason, so that the reliability of data recovery is further improved.
In specific implementation, in order to enable a manager to obtain a data reduction result and a working state of a system to be reduced so as to take corresponding operations on the system to be reduced, a reduction report needs to be generated.
On the basis of the above embodiment, after the step of restoring the data of the system to be restored according to the backup data, the method further includes:
and generating a restoration report to record the information of the restored data in the system to be restored.
It can be understood that recording the data reduction event may include recording information such as the number of times of data reduction of the current device, whether the data reduction is successful, and version information of the reduced data, and may also include different conditions occurring in the reduction process, for example: and if the data recovery fails, the reason that the data is not successfully recovered is recorded, so that management personnel can analyze and maintain the equipment conveniently.
It should be noted that after the data is restored and recorded into the log file, the log file may be saved in the local device, or may be saved in a remote server for storing the mirror image file library. Compared with the former scheme, the method for storing the log file in the remote server has the advantages of being convenient to check and not prone to losing data due to equipment failure.
In the embodiment, the reduction report is generated to record the information of the reduced data in the system to be reduced, so that the management personnel can know the working state of the equipment conveniently, and data support is provided for the subsequent development work.
In the foregoing embodiments, detailed descriptions are given to the data restoring method, and the present application also provides embodiments corresponding to the data restoring apparatus.
