Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart illustrating a file processing method performed by a first client associated with a first server according to an embodiment of the present invention. The file processing method provided by the embodiment can be applied to the case of recovering the target file which is subjected to the misoperation, and typically, the embodiment of the invention can be applied to the case of accurately determining the file which needs to be recovered according to the operation record information and recovering the file when the file is subjected to the misoperation. The method may particularly be performed by a file processing apparatus, which may be implemented by means of software and/or hardware, which may be integrated in a device loaded with the first client. Referring to fig. 1, the method of the embodiment of the present invention may be performed by a first client in a first server, and includes:
s110, if the high-risk processing operation on the target file is monitored according to the user input information, determining the operation record information of the target file.
The user input information may be operation instruction information input by a user, may be an input code statement, or may be operation instruction information generated by triggering a control. The high-risk processing operation may be an operation other than a restore operation on the target file, such as delete, move, copy, add content, delete content, and the like. The operation record information comprises the high-risk processing operation time of the target file, the storage directory and the target file identification information and is used for recovering the target file.
For example, since the high-risk processing operation may change the file, and if the high-risk processing operation is an error operation, the file may be changed and cannot be restored to the original file, the high-risk processing operation needs to be monitored, so that when the high-risk processing operation is monitored, the operation record information of the target file is determined in time, and it is convenient to accurately restore the target file when the target file needs to be restored subsequently.
Specifically, the above steps can be implemented by redefining the high-risk processing operation instruction. For example, the first client searches for instructions corresponding to all high-risk processing operations that can act on the target file in the first server, such as rm, move, copy instructions, and the like, renames the instructions, for example, renames rm to rm _ back, adds a corresponding instruction code for obtaining operation record information of the target file to rm _ back, and repackages the instruction as the content executed by the rm _ back instruction. And then placing the command tool which is re-packaged and renamed in the first client under the path of the original tool so as to be called. When the first client monitors the instruction of the high-risk processing operation, because the writing mode of the instruction is still the conventional mode, the instruction needs to be firstly analyzed and replaced by the repackaged and named instruction. For example, for the instruction rm-fr/usr/lib, it is parsed into rm _ back-fr/usr/lib/xx 1; rm-fr/usr/lib/xx2.. the execution is to firstly traverse all the files in each storage directory, store the related information of the files, such as file names, summary information obtained by calculation, and the like, and then execute corresponding processing operation. Similarly, mv/home/xx/usr/lib/can be resolved as mv _ back/home/xx/xx 1; mv _ back/home/xx/xx2 … …, mv _ back/usr/lib/xx 1; mv _ back/usr/lib/xx2 … …. For operations such as file modification or file addition, since an operation for a specific file is indicated, operation record information of a target file for executing the operation can be directly saved without traversing.
In the embodiment of the present application, monitoring a high risk processing operation of an object file according to user input information includes: according to a file processing instruction which is input by a user and comprises any file name, taking the file as the target file, and determining to monitor high-risk processing operation on the target file; or according to a file processing instruction which is input by a user and comprises any file storage directory, all files in the file storage directory are used as the target files, and the high-risk processing operation of the target files is determined to be monitored.
For example, the file processing instruction may be a file processing instruction including a file name, e.g., rm-fr/usr/lib/xx. At this time, the file is used as a target file, and the operation record information of the file is acquired. rm-fr/usr/lib represents that all files under the storage directory are processed, at this time, all files under the directory are taken as target files, all files under the directory are traversed, and operation record information of all files is obtained.
In this embodiment of the present application, determining the identification information of the target file includes: determining abstract information of the target file; and taking the abstract information and the name of the target file as the identification information of the target file.
Illustratively, the first client acquires a target file, i.e. a file to be processed, or all files in the storage directory and the subdirectories, calculates digest information of each target file one by one, such as md5 value, SHA1 value, SHA256 value, and the like, and uses the name and digest information of the target file as identification information of the target file. In addition, the time for acquiring the high-risk processing operation of the target file may be, for example, the time for receiving the high-risk processing operation on the target file, or the time for executing the high-risk processing operation on the target file. And acquiring the storage directory where the target file is located, so that the operation record information comprises the high-risk processing operation time of the target file, the storage directory and the identification information of the target file.
S120, executing high-risk processing operation on the target file, and sending operation record information of the target file to a second client so that the second server stores the operation record information; wherein the second client is hosted in the second server;
the operation record information is used for acquiring the target file from the second server according to the operation record information when a recovery instruction of the target file is monitored, and recovering the target file in the first server.
Illustratively, when the first client monitors high-risk processing operation on the target file, the first client performs queue storage on operation record information of the target file and executes the high-risk processing operation on the target file. And if the current high-risk processing operation is suspended, terminated or the queue storage is full, transmitting the operation record information saved in the queue to the second client. The sending format may include a message type, a message ID, a message timestamp, a client IP sending the message, a mac address corresponding to the client IP, a network card number, a data part byte length, a data part, and the like, as shown in table 1. The message type of the operation record information reported by the first client may be a digital number, for example, 03, the message timestamp is the high-risk processing operation time of the target file, and the data portion includes an operation instruction of the high-risk processing operation, a name and summary information of the target file, and the like.
TABLE 1
And after receiving the operation record information, the second client extracts the high-risk processing operation time, the operation instruction of the high-risk processing operation, the name and the abstract information of the target file and the like from the operation record information and stores the extracted high-risk processing operation time, the operation instruction of the high-risk processing operation, the name and the abstract information in the second server. When the first client monitors a recovery instruction of the target file, the second client acquires operation record information from the second server, acquires the target file from the second server according to the operation record information, and recovers the target file in the first server. The operation record information of the target file is sent to the second client, so that the second server stores the operation record information, the problem that the first client deletes the operation record information due to misoperation and cannot recover the target file according to the operation record information is solved, and the storage safety of the operation record information is guaranteed.
In the embodiment of the present application, the operation record information may be stored in a first server associated with the first client, and when the operation record information in the first server is not deleted by an erroneous operation, the target file may be restored according to the operation record information stored in the first server.
In the embodiment of the application, if the high-risk processing operation on the target file is monitored according to the user input information, the operation record information of the target file is determined, so that when the target file needs to be restored, the target file to be restored can be determined in a targeted manner according to the operation record information, and the restoration can be performed. The operation record information of the target file is sent to the second client, so that the second server stores the operation record information, the problem that the first client deletes the operation record information by misoperation and cannot recover the target file according to the operation record information is solved, and the storage safety of the operation record information is ensured.
Fig. 2 is a flowchart illustrating a file processing method executed by a first client associated with a first server according to another embodiment of the present invention. For further optimization of the embodiments, details which are not described in detail in the embodiments are described in the embodiments. Referring to fig. 2, the file processing method provided in this embodiment may include:
s210, if the high-risk processing operation on the target file is monitored according to the user input information, determining the operation record information of the target file.
In another embodiment of the present application, if a high-risk processing operation on an object file is monitored according to user input information, before determining operation record information of the object file, the method further includes: and sending registration information and keep-alive information to the second client so that the second client verifies and registers the first client according to the registration information and establishes communication connection with the first client.
Illustratively, the second client listens to a default port, e.g., 3910, and if the port is found to be occupied, increments the listening port number to the unoccupied port. The first client initiates a registration with an available port of the second client via a communication protocol, such as TCP, and sends a registration message or a keep-alive message to an incremented default port number if the registration is abnormal. And when the second client successfully receives the registration information or the keep-alive information of the first client, returning a response message, such as ok, to the first client. The format of the registration information is shown in table 1, the message type may be 01, and the keep-alive message type may be 02. And sending a registration message and a keep-alive message to the second client by the first client for registration and keep-alive, so that a trusted communication connection is established between the first client and the second client, and the subsequent sending and receiving of the operation record information are facilitated.
S220, executing high-risk processing operation on the target file, and sending operation record information of the target file to a second client so that the second server stores the operation record information; wherein the second client is associated with the second server.
And S230, if a recovery instruction for any target file is monitored, acquiring operation record information of the target file.
For example, if the high-risk processing operation on the target file is directly performed, when the high-risk processing operation on a part of the target file is an error operation, the part of the target file cannot be restored in a targeted manner. Therefore, in the embodiment of the present application, the operation record information of the target file is stored, and when a recovery instruction for any target file is detected, the stored operation record information of the target file is acquired, so that specific information of the target file which needs to be replied can be determined, and the target file which needs to be recovered is recovered.
In another embodiment of the present application, the obtaining operation record information of the target file includes: sending an operation record information query request to a second client; the operation record information query request comprises high-risk processing operation time of a target file, so that a second client determines operation record information to be returned according to the high-risk processing operation time of the target file; and receiving operation record information returned by the second server in response to the operation record information query request.
In order to improve the storage safety of the operation record information and avoid the operation record information from being deleted by the misoperation of the first client, the operation record information is saved in the second server. When the first client monitors a recovery instruction of any target file, an operation record information query request is sent to the second client so as to obtain operation record information from the second server. And the second client inquires the operation record information of the target file matched with the time according to the high-risk processing operation time of the target file in the operation record inquiry request, so that the operation record information is returned to the first client, and the first client receives the operation record information. When the second client side stores the operation record information, the second client side extracts the relevant operation record information from the message which is sent by the first client side and carries the operation record information to store the operation record information, so that when the operation record information is returned to the first client side, the second client side rebuilds the operation record information according to the message sending format in the table 1 to send the operation record information through the message format in the table 1, and the first client side is ensured to be capable of accurately receiving the operation record information. Wherein the message type may be set to 05 to distinguish from other messages.
And S240, acquiring the target file from the second server according to the operation record information.
In another embodiment of the present application, acquiring a target file from a second server according to the operation record information includes: determining a first storage directory of a target file in the first server and a second storage directory in the second server according to the storage directories in the operation record information; acquiring a target file from the second storage directory according to the file identification information in the operation record information;
for example, the first client determines, according to a message sent by the second client, an instruction of a high-risk processing operation performed on the target file, and if the instruction includes a name of the target file, it indicates that the high-risk processing operation is a processing operation directly performed on the target file, so that the storage directory of the target file is searched through the instruction or the operation record information. If the instruction only includes the storage directory of the target file, it indicates that the high-risk processing operation is an operation on all files in the storage directory, and therefore, the storage directory is created in the first server to recover the target file. The first server may search for the storage directory in the operation record information, and if the storage directory exists in the first server, the storage directory does not need to be created. If the storage directory does not exist in the first server, the storage directory is created in the first server.
Specifically, the first client hangs the content corresponding to the target file storage directory in the second server to the storage directory of the first server, so as to access the content in the storage directory of the second server and obtain the target file.
In another embodiment of the present application, acquiring a target file from the second storage directory according to file identification information in the operation record information includes: acquiring a candidate file from the second storage directory according to the file name in the operation record information; determining summary information of the candidate file; and if the summary information of the candidate file is the same as that of the target file, determining the candidate file as the target file. After the summary information of the candidate file is determined, the method further comprises the following steps: if the summary information of all the candidate files is different from the summary information of the target file, acquiring a new candidate file from a backup storage directory of a second server according to the file name; determining summary information of the new candidate file; and if the summary information of the new candidate file is the same as that of the target file, determining the new candidate file as the target file.
Illustratively, the summary information of the candidate file is calculated by acquiring a file having the same name as the target file in the operation record information from a storage directory in the second server for hanging the disk, as the candidate file. And if the summary information of the candidate file is consistent with the summary information in the operation record information, the candidate file is the target file to be recovered. If the file name is not consistent with the name of the target file in the operation record information, the target file in the storage directory of the second server is changed, so that the file with the same name as the target file in the operation record information is inquired through the backup storage directory in the second server and is used as a new candidate file, and the summary information of the new candidate file is calculated. And if the summary information of the new candidate file is consistent with the summary information in the operation record information, the new candidate file is the target file to be recovered.
In another embodiment of the present application, if the second client monitors the high-risk processing operation on the target file in the second server, the second client stores the target file in the backup storage directory to backup the target file, and then executes the high-risk processing operation on the target file in the second server.
S250, storing the acquired target file into the first server so as to recover the target file in the first server.
Correspondingly, the storing the obtained target file in the first server includes: and storing the target file in a first storage directory in the first server.
And the first client acquires a file consistent with the related information of the target file in the operation record information through the second server storage directory, and stores the file in the storage directory of the first server to recover the target file. And after the target file is recovered, removing the hanging disc.
According to the technical scheme of the embodiment of the invention, when the recovery instruction of any target file is monitored, the operation record information of the target file is acquired, the target file is acquired from the second server according to the operation record information, and the target file is stored in the first storage directory of the first server, so that the target file to be recovered is accurately determined according to the operation record information without recovering all the target files, and the recovery efficiency of the target file is improved. And in the process of obtaining the target file, double searching is carried out according to the name and the storage directory of the target file, so that the accuracy of the target file is ensured.
Fig. 3 is a flowchart of a file processing method executed by a second client associated with a second server according to an embodiment of the present invention. The file processing method provided by the embodiment can be applied to the case of recovering the target file which is subjected to the misoperation, and typically, the embodiment of the invention can be applied to the case of accurately determining the file which needs to be recovered according to the operation record information and recovering the file when the file is subjected to the misoperation. The method may particularly be performed by a file processing apparatus, which may be implemented by means of software and/or hardware, which may be integrated in a device loaded with the second client. The details such as explanation of the concept of the noun and the like, which are not described in detail in the present embodiment, are described in detail in the above embodiments. Referring to fig. 3, the method of the embodiment of the present invention may be performed by a second client associated with a second server, and includes:
and S310, receiving operation record information sent by the first client.
Illustratively, when the first client monitors high-risk processing operation on the target file, the first client performs queue storage on operation record information of the target file and executes the high-risk processing operation on the target file. And if the current high-risk processing operation is suspended, terminated or the queue storage is full, transmitting the operation record information saved in the queue to the second client. And the second client receives the operation record information sent by the first client.
