Embodiment 1

[0073] refer to figure 1 , shows a flow chart of steps of a file storage method according to Embodiment 1 of the present invention.

[0074] The method for file storage of this embodiment may include the following steps:

[0075] Step 101, according to the size of the received file uploaded by the client, store the content data of the file in at least one file storage block.

[0076] In the embodiment of the present invention, the client can upload files to the file system, and can also download files from the file system. Wherein, the file system may be a file system under an operating system such as Linux.

[0077] When the file system receives the file uploaded by the client, it can first obtain the size of the file, and then determine which file storage block or blocks the content data of the file should be stored in according to the size of the file, that is, according to the received client The size of the file uploaded by the end, and the content data of the file is ...

Embodiment 2

[0088] refer to figure 2 , shows a flow chart of steps of a file storage method according to Embodiment 2 of the present invention.

[0089] The method for file storage of this embodiment may include the following steps:

[0090] Step 201, receiving a file uploaded by a client.

[0091] As mentioned above, the client can upload files to the file system, and can also download files from the file system.

[0092] Step 202, according to the size of the file, store the content data of the file in at least one file storage block.

[0093] According to the size of the received file, the content data of the file may be stored in at least one file storage block, where the file storage block refers to the storage space of the file system. In this embodiment, a standard size can be preset, and according to the standard size, it can be determined that the content data of the file is stored in one file storage block or multiple file storage blocks. For example, the standard size can b...

Embodiment 3

[0166] refer to image 3 , shows a structural block diagram of a file storage device according to Embodiment 3 of the present invention.

[0167] The file storage device of the present embodiment may include the following modules:

[0168] A content storage module 301, configured to store the content data of the file in at least one file storage block according to the size of the received file uploaded by the client;

[0169] An information obtaining module 302, configured to obtain information of a file storage block storing the content data;

[0170] A metadata generation module 303, configured to generate metadata corresponding to the content data according to the information of the file storage block;

[0171] The metadata storage module 304 is configured to store the metadata of the file in a preset storage space.

[0172] In the embodiment of the present invention, the content data of the file is stored in at least one file storage block according to the size of the f...

Abstract

The invention provides a file storage method and device, and is used for solving the problems that fragments or overflowing is always caused since a traditional file storage way is unreasonable and file query efficiency is low. The method comprises the following steps: according to the size of a received file uploaded by a client side, storing the content data of the file into at least one file storage block; obtaining the information of the file storage block which stores the content data; according to the information of the file storage block, generating metadata corresponding to the content data; and storing the metadata of the file into a preset storage space. The disk fragments or overflowing caused in a way that all content data of the file is directly stored into the corresponding storage space as a whole can be avoided, a storage mode is more reasonable, the metadata is independently stored, and therefore, the metadata of the file can be uniformly managed so as to improve the query efficiency of a subsequent file.

Description

technical field [0001] The present invention relates to the technical field of files, in particular to a method and device for storing files. Background technique [0002] A file system is a mechanism for providing data access to users. From a system perspective, a file system is a system that organizes and allocates space on file storage devices, is responsible for file storage, and protects and retrieves stored files. When the file uploaded by the client is received, the file is stored in the corresponding storage space, and when the request for downloading the file is received, the corresponding file is searched from the storage space, and the found file is delivered, realizing the file upload and download, which is convenient for users to use. A file can include content data and metadata. Content data refers to the actual data in the file. Metadata records the relevant information of the file and is used to describe the attributes of the file, such as the creation time...
