Abstract

The invention provides a file storage method. The method comprises the steps of responding to a hash value list which is sent by a sending device and calculates data blocks of a file to be stored, and determining whether the hash value list of the file to be stored is matched with a hash value list of a stored file; and if the hash value list of the file to be stored is not matched with the hash value list of the stored file, informing the sending device to send content of the file to be stored starting from the data block corresponding to the first unmatched hash value in the file to be stored until content of the file to be stored is ended, and storing the file to be stored according to received data blocks. According to the file storage method, through the file level storage method, the file index can be maintained at a low cost, so that processing resources and performance expenses of a receiving device are reduced. Besides, the invention provides a file storage device, such as a server. Additionally, the invention further provides a file sending method and device, such as a client.

Description

technical field [0001] The embodiments of the present invention relate to the Internet field, and more specifically, the embodiments of the present invention relate to a file storage method and device, and a file sending method and device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein may include concepts that could be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.
