Data storage method and storage server

Abstract

The invention discloses a data storage method. The data storage method is applied to a system which comprises a storage server and a plurality of terminals. The data storage method comprises the following steps of: pre-generating a plurality of storage files in the storage server; when a terminal stores data to the storage server, obtaining an ID of the terminal to search the last index information of a corresponding storage file linked list; if a storage ending time in the index information is empty, storing the data of the terminal to a first storage file corresponding to the index information; otherwise, obtaining a second storage file, the state of which is empty, according to a storage file state table in the storage server and storing the data of the terminal into the second storage file; and when the states of all the storage files in the storage file state table are not empty, obtaining a third storage file, the storage time of which is earliest, in the storage server and storing the data of the terminal to the third storage file. According to the data storage method disclosed by the invention, the storage files are pre-established, so that file fragments are not generated due to the deletion of the storage files in later period, and the data of the terminal can be flexibly stored.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage method, and in particular to a storage server. Background technique [0002] With the development of computer technology and multimedia technology, data storage has been applied in various aspects, and the requirements for each hardware terminal are also higher and higher. [0003] Taking video surveillance as an example, video surveillance has become more and more widely used. Because of the effective use of client PC resources, the video surveillance software PC-NVR has been more and more widely used in some small surveillance projects with tight budgets. In these applications, users often need to store part or all of the audio and video of the IPC connected to the PC-NVR on the PC running the PC-NVR. Since the PC running PC-NVR does not only run the PC-NVR software, it is necessary to ensure the stable operation of the PC-NVR and the stable operation of ot...

Problems solved by technology

[0005] (1) When an IPC needs to be stored, create an audio and video file and write the audio and video of the IPC until the IPC is offline or cut off. The disadvantage of this is that the saved file may be too large or too small. A little abnormality in the file will cause the file to be damaged and cannot be played, or the number of files is too large, which will cause the subsequent query retrieval speed to be slow

[0006] (2) Continuously store the audio and video of the IPC. When the stored audio and video fill up the free hard disk space of the PC, it will affect the normal operation of other software on the PC.

[0007] (3) On the other hand, if you do not delete the stored audio and video files, the storage will be suspended, resulting in the failure to store the latest video. If you delete the saved video files, it will lead to frequent deletion and creation of files, resulting in file fragments , which may cause the file system of the PC to crash

[0008] How to solve the problem of file fragmentation in the process of storing files in the process of data storage has become an urgent problem to be solved by people in the industry
