Problems solved by technology

Assuming that the file sharing source server and the destination server are two independent servers, and the two servers are connected through a high-speed Gigabit / 10 Gigabit switch, when the client needs to copy files from the source server to the destination server, the traditional way for the client The terminal can only read the file data from the source server to the local through the low-speed network, and then write the data from the local to the destination server. The high-speed network connection between the servers has not been effectively utilized.

[0032] figure 2 A flow chart of the steps of the first embodiment of the present invention is shown. The method of the first embodiment described in the present invention supports the copy operation when the source server and the destination server are the same server, that is, the source directory where the copied file is located and the destination directory are located on the same shared server. The read operation authorization, that is, there is no need to call the above-mentioned copy_offload_notify and copy_offload_revoke operations, the file copy is completely performed inside the server, and the copy result is returned to the client after the copy is completed.

[0033] Such as figure 2 Shown, this embodiment comprises the following steps:

[0034] S1: The client sends a copy_offload message to the file server (the source server and the destination server are the same file server) to notify the file server to perform asynchronous copying.

[0035] S2: The client s...

[0038] image 3 and Figure 4 It shows the second embodiment proposed by the present invention, and the method described in it also supports the synchronous copy operation and the asynchronous copy operation of the file. For the synchronous copy, the copy_offload call will return only after the copy operation is completed, and the asynchronous copy is initiated by the client After copy_offload is called, it will return immediately, and the final copy result will be sent to the client through the copy_offload_callback callback. For asynchronous copying, the above-mentioned copy_offload_status, copy_offload_abort, and copy_offload_callback operations need to be implemented.

[0039] image 3 Shows the synchronous copy step process in the second embodiment, including:

[0040] S21: The client sends a copy_offload_notify message to the source server, notifying the source server to authorize the read file operation of the destination server;

[0041] S22: the client sends a cop...

Abstract

The invention provides a rapid copying method of a server file. The file is read from a source server through an objective server according to a message sent out of a client directly and then the copying result is fed back to the client. According to the rapid copying method of the server file, the unnecessary file transmission to the client is avoided, the high speed network connection between servers is effectively utilized, and the copying efficiency of the file is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to fast copying of server-side files. Background technique [0002] In a network file sharing environment, usually the client needs to copy data from one shared directory of the file server to another shared directory, or copy data from one file server to another file server. In both cases, the client needs to copy the Data is read from the source file directory to the local, and then written back to the destination file directory, which consumes a lot of network transmission bandwidth, and usually the hardware configuration of the client is lower than that of the file server. During the data transfer process, the client itself is also the bottleneck point. [0003] attached figure 1 A server-side file copy method in the prior art is shown. Assuming that the file sharing source server and the destination server are two independent servers, and the two servers are connected throu...
