Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The file recovery method of the present invention is described below in conjunction with fig. 1-4.
Fig. 1 is a schematic flow diagram of a file recovery method provided by the present invention, and as shown in fig. 1, the file recovery method includes the following steps:
The file to be monitored is a file stored in a magnetic disk.
For example, when a user needs to monitor a file stored in a disk, which is considered to be important by the user, identification information of the file to be monitored may be input on a corresponding interface of the device, where the identification information may be a name of the file to be monitored; in addition, the user may input the name of one file to be monitored, or may input the names of a plurality of files to be monitored, which is not limited in the present invention.
And 102, running the file to be monitored through a target process based on the identification information.
For example, when the identification information of the file to be monitored input by the user is acquired, the corresponding file to be monitored may be acquired in the disk based on the identification information, the target process is started, and the file to be monitored is operated by the target process, so that the file to be monitored is occupied.
It can be understood that when the identification information of a plurality of files to be monitored input by a user is obtained, the corresponding files to be monitored can be obtained in the disk based on each identification information, and a target process is started for each file to be monitored, and each target process runs one file to be monitored; for example, a user inputs identification information of 3 files to be monitored, which are respectively name a1, name a2 and name A3, and when the three names are obtained, the file to be monitored corresponding to the name a1, the file to be monitored corresponding to the name a2 and the file to be monitored corresponding to the name A3 are obtained from a disk; and then starting three target processes, namely a process 1, a process 2 and a process 3, running the file to be monitored corresponding to the name A1 through the process 1, running the file to be monitored corresponding to the name A2 through the process 2, and running the file to be monitored corresponding to the name A3 through the process 3.
And 103, acquiring a file handle of the file to be monitored, and correspondingly storing the file handle and the file to be monitored in an internal memory.
The file handle may be identification information of the file to be monitored, or may be other information that is convenient for remembering the file to be monitored.
For example, the obtaining of the file handle of the file to be monitored may specifically be: in actual service, when monitoring is often performed on a file to be monitored for the first time, the file handle needs to be created for the file to be monitored, and in the process of performing continuous monitoring on the file to be monitored for which the file handle is created, the created file handle can be directly obtained subsequently without repeated creation. In the scheme, after the file handle of the file to be monitored is obtained, the file handle and the file to be monitored are correspondingly stored in the memory, specifically under the directory of the process number of the target process in the memory.
It can be understood that when the identification information of a plurality of files to be monitored input by a user is obtained, a file handle of each file to be monitored needs to be obtained, and each file handle and the corresponding file to be monitored are stored in corresponding positions in the memory; for example, if the file to be monitored corresponding to the name a1 is run through the process 1, the file to be monitored and the file handle corresponding to the name a1 are stored in the memory under the directory of the process number of the process 1; if the file to be monitored corresponding to the name A2 is operated through the process 2, storing the file to be monitored corresponding to the name A2 and the file handle in the directory of the process number of the process 2 in the memory; if the file to be monitored corresponding to the name A3 is run through the process 3, the file to be monitored and the file handle corresponding to the name A3 are stored in the directory of the process number of the process 3 in the memory.
And 104, when it is monitored that the file to be monitored in the disk does not exist, acquiring the corresponding file to be monitored in the memory based on the file handle.
For example, after the file to be monitored is run through the target process, a timing task may be added, the existence of the file to be monitored in the disk is automatically monitored at regular intervals, and when the file to be monitored in the disk is monitored to be absent, it is indicated that the file to be monitored may be deleted by mistake; and acquiring the corresponding file to be monitored in the memory based on the file handle.
And 105, restoring the file to be monitored to the disk.
Illustratively, when the corresponding file to be monitored is found in the memory based on the file handle, the file to be monitored is automatically copied to the original storage position according to the original storage position of the file to be monitored in the disk, so as to realize the automatic recovery of the deleted file to be monitored in the disk. For example, when it is monitored that a file to be monitored corresponding to the name a2 in the disk is lost, the file handle of the file to be monitored corresponding to the name a2 is used to search the file to be monitored corresponding to the name a2 in the directory of the process number of the process 2 in the memory, and the searched file to be monitored corresponding to the name a2 is copied to the disk, so that the file to be monitored corresponding to the name a2 in the disk is automatically recovered.
When the identification information of the file to be monitored input by a user is acquired, the corresponding file to be monitored is operated through a target process based on the identification information, the handle of the file to be monitored is acquired, and the file handle and the file to be monitored are correspondingly stored in a memory; when it is monitored that the file to be monitored in the disk does not exist, the file to be monitored in the memory can be restored to the disk based on the file handle. Because the file operated by the process cannot be deleted by mistake, the recovery of the deleted file in the disk can be ensured, and the success rate of file recovery is improved.
Optionally, fig. 2 is a second schematic flow chart of the file recovery method provided by the present invention, as shown in fig. 2, step 102 in fig. 1 may be specifically implemented by the following steps:
For example, when the identification information of the file to be monitored input by the user is acquired, a storage path corresponding to the identification information may be searched in the path list, where the storage path is a storage path of the file to be monitored in the disk; the path list is pre-established, and the path list stores the corresponding relationship between the identification information of each file stored in the disk and the storage path.
And step 1022, acquiring the file to be monitored based on the storage path.
For example, when a storage path of the file to be monitored in the disk is acquired, the file to be monitored may be acquired in the disk based on the storage path.
And 1023, starting the target process to run the file to be monitored.
Illustratively, when a file to be monitored is acquired from a disk, a target process is started, and the file to be monitored is operated through the target process, so that the file to be monitored is occupied in a memory.
According to the file recovery method provided by the invention, the storage path of the file to be monitored in the disk can be obtained based on the mark information, so that the target process can obtain the file to be monitored based on the storage path, and the normal operation of the file to be monitored by the target process is realized.
Optionally, fig. 3 is a third schematic flow chart of the file recovery method provided by the present invention, and as shown in fig. 3, before the step 104 in fig. 1 is executed, the file recovery method further includes the following steps:
and 106, monitoring the existence of the file to be monitored in the magnetic disk according to a preset period.
The preset period is a preset value, and can be set according to a requirement, for example, the preset period is any time between 0.1 second and 1 second.
Illustratively, the disk is accessed according to a preset period, and the existence of the file to be monitored in the disk is monitored.
The file recovery method provided by the invention monitors the file to be monitored in the disk according to the preset period, thereby realizing the automatic monitoring of the existence of the file in the disk.
Optionally, the monitoring of the existence of the file to be monitored in the disk according to the preset period may be implemented by:
determining whether the file to be monitored is found in the disk or not based on the storage path according to a preset period; when the file to be monitored is found in the magnetic disk, determining that the file to be monitored exists; and when the file to be monitored is not found in the magnetic disk, determining that the file to be monitored does not exist.
Illustratively, according to a preset period, accessing a disk based on an acquired storage path, determining whether a file to be monitored is found in the disk, if the file to be monitored is found in the disk, indicating that the file to be monitored in the disk is not deleted by mistake, namely determining that the file to be monitored exists, and doing no action at this time; if the file to be monitored is not found in the disk, the file to be monitored in the disk is possibly deleted by mistake, and the file to be monitored is determined to be absent.
The file recovery method provided by the invention can automatically monitor the existence of the file to be monitored in the disk based on the storage path, and a user does not need to manually check whether the file exists in the disk, so that the efficiency of monitoring the existence of the file is improved, and meanwhile, the file which is deleted by mistake in the disk can be conveniently found in time.
