- Step 17 The service process sends the returned application data to the backup software by using the socket.
- the backup software and the service process can interact through the socket connection.
- the service process can interact with the application software because it has root operation authority.
- the specific commands, data, and so on of the backup software, the service process, and the application software can be different depending on whether the data is to be backed up or restored.
- For the specific interaction process refer to the subsequent process for backup and recovery.
- the interface between the backup software and the service process, and the interface between the service process and the application software may be set to be protected by a signature.
- the received message needs to be first verified by signature.
- the processing is performed.
- the service process receives, by the socket, a processing request for the application data sent by the backup software; the service process performs signature verification on the processing request, and after the signature verification is passed, sends the processing request for the application data.
- the application software performs signature verification, and sends the application data to the service process after the verification is passed.

Since the backup software interacts with the service process to establish a connection first, it can be understood that the following steps are included in the embodiment after the service process is started and the socket connection between the service process and the backup is established.
- the processing request for the application data includes a read directory request or a read file request, and the application data returned by the corresponding application software includes the read directory information or the read file content, and the entire flow of reading the application data is described in detail below.
- Step 31 The backup software sends a read directory request to the service process over the socket connection.
- the backup software when the backup software sends the command word and parameters to the service process, the length of the command word and the parameter may be sent to the service process first, and then the specific content of the command word and the parameter is sent.
- the read directory request when sending a read directory request, can be expressed as opendir+catalogue, where "opendir” is the command word and "catalogue” is the directory path parameter.
- opendir is the command word
- catalogue is the directory path parameter.
- Step 32 The service process sends a read directory request to the corresponding application software according to the read directory request.
- the service process may determine the content of the corresponding length according to the length of the received command word and the parameter, and determine the specific content of the command word and the parameter, that is, determine the specific content of the read directory request.
- the read directory request carries the information of the directory, such as the directory path parameter catalogue described above

- the A application software returns the directory included in the A application software to the service process, such as the file information included in the directory 1, the file information included in the directory 2, and the directory. 3 Included file information, etc. It can be understood that since the read directory request is usually one directory at a time, the result returned is usually a related information of a directory.
- Step 34 The service process sends the read content to the backup software through the socket connection.
- the read content may be information of a directory included in a result returned by the application to the service process, such as file information included in the directory 1, file information included in the directory 2, file information included in the directory 3, and the like.
- the service process can store the read content in a buffer, and then send the data stored in the cache, that is, the read content, to the backup software.
- the cache can be understood as a data area in which data is stored.
- the service process can first send the length of the read content, which can be expressed in the form of a 16-bit unsigned short (unsigned short 16bit), and then send the read content to the backup software.
- the backup software reads the data of the corresponding length according to the length of the read content, and then the backup software can perform backup processing on the read data.
- Step 35 The backup software sends a read file request to the service process.
- the backup software can first send the length of the read file request, and then send the contents of the specific read file request.
- Step 36 The service process sends a read file request to the corresponding application software.
- the read file request sent by the backup software carries the file information.
- the read file request is an open+ file path, and the file path may indicate the path information of the file to be opened.
- the service can find the corresponding application software to the file path in the read file request.
- Step 37 The application returns results to the service process.
- the returned result may include content related information of the file, such as the content of the file, the format of the file, the operation authority of the file, and the like.
- Step 38 The service process returns the contents of the file to the backup software.
- FIG. 4 is a schematic flowchart of another embodiment of a method for processing application data according to the present invention.
- This embodiment takes a recovery process as an example. Since the backup software and the service process need to establish a connection first, it is understood that the present embodiment includes the following steps after the service process is started and a socket connection between the service process and the backup software is established.
- the processing request for the application data includes a write directory request or a write file request
- the application data returned by the corresponding application software includes a result corresponding to the write directory request or corresponds to the write file request.
- Step 41 The backup software sends a write directory request to the service process through the socket connection.
- the backup software when sending a write directory request, can be similar to the processing of the read directory request, first sending the length of the write directory request and then sending the specific content of the write directory request.
- the directory includes directory 1, directory 2, directory 3 ⁇ , and directory 1 includes file 1, file 2, ....
- the above write directory request usually includes information about a directory.
- the write directory request format is: writeDir+ directory name.
- multiple directories can be placed in the same request, separated by special characters.
- the format of the write directory request is: writeDir+ directory name 1; directory name 2; directory name 3.
- Step 42 The service process sends a write directory request to the corresponding application software according to the write directory request.
- the service process may determine a corresponding handle according to the directory name included in the write directory request, and then send a write directory request to the application indicated by the handle, which may include file information included in the directory.
