File storage method and system

Abstract

The invention provides a file storage method which is applied to a storage device. The file storage method includes the steps that large files for merging and storing small files written by a front-end device are created in local; when the small files written by the front-end device are received, index information of the small files is cached in local; the large files are appointed for the small files, the small files and corresponding description information are written into the appointed large files according to the written-in sequence, and the cached indexing information of the small files is written into small file indexing areas in batch according to the written-in sequence when new data cannot be written into the large files any more or writing is timed out, wherein the indexing information comprises access paths of the appointed large files and starting offset of the small files in the large files. By means of the file storage method, the written-in performance of the small files can be improved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a file storage method and system. Background technique [0002] With the rapid development of the bayonet monitoring business, the storage of small files such as single pictures has become a major problem in the industry. At present, the existing solutions for the storage of small files in the industry are mainly realized through file systems or cloud storage solutions. [0003] However, when storing small files through the file system, file fragments are prone to occur after a long period of full coverage, and the storage performance is low; while storing small files through cloud storage solutions, such as Hadoop solutions, cluster devices or multiple If a replica store stores small files, there will still be problems of low storage performance and a waste of storage space. Contents of the invention [0004] In view of this, the present invention proposes a small file storag...
