Problems solved by technology

[0007] The invention provides a method for storing video files, which is used to solve the problem in the prior art that the video files stored in the disk array cannot be read normally according to the file index in the case of a problem with the disk. The method is applied to disk array RAID storage system, including:

Embodiment Construction

[0019] As described in the background art, when multiple disks in the RAID storage system fail, the file indexes of the stored video files in the RAID storage system will be destroyed, thus making the stored video files inaccessible. Even if the index of all video files in the current RAID storage system is completely copied on other disk arrays or other devices through redundant backup. However, the file system structure will take up a lot of space as an index area, and whether it is a simple backup or a full backup, it will reduce the performance of other logical volumes, thereby affecting the video recording business.

[0020] In view of the problems in the prior art, the present invention proposes a video file storage method, which is applied in a disk array RAID storage system, such as figure 1 shown, including the following steps:

[0021] S101, write the video file into a blank segment data segment, and obtain and save the address of the segment data segment after the ...

Abstract

The invention discloses a video file storage method and device. A video file is written into a blank fragmentation data section; after the video file finishes being written, the address of the fragmentation data section is obtained and stored; and since the fragmentation data section corresponds to the record file one by one and the length of the fragmentation data section is greater than the size of the record file, the record data of the record file is obtained in the fragmentation data section according to the address of the fragmentation data section when the file index of the record file is abnormal. Therefore, on a premise that storage performance is not lowered, the problem in the prior art that the file index in an RAID (Redundant Array of Independent Disks) storage system is damaged to prevent the record file from being read can be solved, and the stability of the RAID storage system is improved.

Description

technical field [0001] The invention relates to the field of video data storage, in particular to a video file storage method. The invention also relates to a video file storage device. Background technique [0002] With the vigorous development of network technology and the gradual maturity of digital, networked, high-definition, and intelligent video surveillance, video surveillance front-end camera video acquisition technology is also developing rapidly, from the early 100,000 pixels to today's 2 million, 5 million The video resolution is getting higher and higher, and the amount of information in the video screen is also getting richer. As the final collection and distribution center of security video management system information, people pay more and more attention to storage technology. [0003] In the video surveillance industry, ensuring that historical videos can be played as much as possible is a key indicator to measure the robustness of a video surveillance sys...
