Video data storage system, operating method thereof, and index server

Abstract

The invention discloses a video data storage system and an operation method thereof, and an index server. The video data storage system of the present invention includes an index server and at least two storage servers for storing video data, the index server stores a first mapping relationship between the camera identification code and the storage server identification code, and the storage server stores the camera identification code, The second mapping relationship between the time range of the video data and the physical location in the storage server; the operation method includes the following steps: the index server counts the operation heat value of each client on the video data, and compares whether the operation heat value of the video data is high. At the predetermined first threshold, if yes, the index server sends a backup instruction to at least one storage server, instructing the storage server to back up the video data and update the second mapping relationship. The present invention can protect the hottest data with the least capacity and the lowest bandwidth consumption.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video data backup and retrieval method and system thereof. Background technique [0002] At present, video cloud storage technology has been widely used. Video cloud storage technology can gather a large number of storage devices in the network to work together through cluster applications and distributed file systems to provide storage and access to video data externally. [0003] In practice, it has been found that the volume of monitored video data is huge, but at the same time its value density is very low. A common video data backup method commonly used at present is to specify the number of redundant copies when the video data is written. The above method leads to a large amount of useless and redundant video data occupying a large amount of storage space and bandwidth resources, which affects resource utilization efficiency. [0004] At the same time, in the current cl...

The above method leads to a large amount of useless and redundant video data occupying a large amount of storage space and bandwidth resources, which affects the efficiency of resource use

[0004] At the same time, in the current cloud storage solution for monitored video data, the miniature information of all video data is usually recorded in the index server. With the popularization of high-definition video surveillance applications and the expansion of the capacity of a single storage server, this method This not only increases the pressure on the index server to manage the storage server and the management of index records, but also leads to a decrease in retrieval efficiency.
