Referring to fig. 1, fig. 1 is a first flowchart of a file sharing method according to an embodiment of the present disclosure.
The file sharing method provided by the embodiment of the application is applied to a server of a file sharing system, and can comprise the following steps:
step S101: shared files are determined in a shared directory.
In practical applications, a server of the file sharing system may determine a shared file in a shared directory first, specifically, a file in the shared directory specified by a user may be determined as a shared file under the control of the user, and the like.
Step S102: a snapshot directory corresponding to the shared directory is created.
In practical application, when a shared file needs to be restored, a corresponding snapshot file needs to be generated, and the shared file is restored by means of the snapshot file.
In a specific application scenario, the snapshot directory may be created near the shared directory so as to quickly find the snapshot directory corresponding to the shared directory, and certainly, other ways may also be used to create the snapshot directory corresponding to the shared directory, which is not specifically limited herein.
Step S103: and carrying out snapshot on the shared file to obtain a snapshot file.
Step S104: and storing the snapshot file into a snapshot directory.
In practical application, after the snapshot directory corresponding to the shared directory is created, the shared file can be snapshot to obtain a corresponding snapshot file, and the snapshot file is stored in the snapshot directory, so that the corresponding snapshot file can be searched in the snapshot directory subsequently.
In a specific application scenario, the triggering condition for snapshot of the shared file may be determined according to actual needs, and the present application is not specifically limited herein.
Step S105: and sending the corresponding relation between the sharing directory and the snapshot directory to a client of the file sharing system so that the client accesses the snapshot file based on the corresponding relation.
In practical applications, after the snapshot file is stored in the snapshot directory, the correspondence between the shared directory and the snapshot directory may be sent to the client of the file sharing system, so that the client may access the snapshot file and the shared file based on the correspondence.
The file sharing method is applied to a server side of a file sharing system, and shared files are determined in a shared directory; creating a snapshot directory corresponding to the shared directory; carrying out snapshot on the shared file to obtain a snapshot file; storing the snapshot file into a snapshot directory; and sending the corresponding relation between the sharing directory and the snapshot directory to a client of the file sharing system so that the client accesses the snapshot file based on the corresponding relation. According to the method and the device, the shared file can be snapshot to obtain the snapshot file, the snapshot file is stored in the snapshot directories with different sharing targets, and the corresponding relation between the shared directories and the snapshot directories is sent to the client, so that the client can access the shared file and the snapshot file based on the corresponding relation, and the applicability is good.
In the file sharing method provided by the embodiment of the application, in the process of obtaining the snapshot file by snapshotting the shared file by the server of the file sharing system, the shared file can be snapshotted within a preset time length after the snapshot directory is created, so that the snapshot file is obtained.
Specifically, the preset time duration may be a short time duration, for example, the preset time duration may be 10s, so as to implement immediate backup of the shared file.
It should be noted that all operations accessing the share are blocked until the operations are completed, so this way of generating the snapshot file is suitable for application scenarios where there is substantially no shared access at a certain time.
In the file sharing method provided by the embodiment of the application, the server of the file sharing system can judge whether a request for modifying the shared file exists or not in the process of snapshotting the shared file to obtain the snapshot file, and if so, the shared file is snapshotted to obtain the snapshot file. That is, only when the shared file needs to be modified, in order to restore the shared file before modification, the shared file may be snapshot first to obtain a corresponding snapshot file, and after the snapshot file is obtained, the shared file may be modified in response to a request for modifying the shared file.
It should be noted that, this snapshot file generation method may affect the performance of writing, so that it is suitable for an application scenario that has low performance requirement and mainly uses a small file.
In the file sharing method provided by the embodiment of the application, the server of the file sharing system can judge whether the server is idle or not in the process of snapshotting the shared file to obtain the snapshot file, and if so, the server snapshotts the shared file to obtain the snapshot file.
That is, the shared file can be snapshot when the server is idle, and a corresponding snapshot file is obtained.
In the file sharing method provided by the embodiment of the application, the server of the file sharing system performs snapshot on the shared file to obtain the snapshot file, and whether the shared file is accessed or not can be judged, and if not, the shared file is subjected to snapshot to obtain the snapshot file.
That is, the shared file can be snapshot only when the server side does not have the shared file accessed, so as to obtain the corresponding snapshot file.
In the file sharing method provided by the embodiment of the application, after the server of the file sharing system creates the snapshot directory corresponding to the shared directory, in order to prevent a user from modifying the snapshot file maliciously, the permission of the client to the snapshot directory can be set as a read-only permission.
