Data storage method and device and data obtaining method and device

Abstract

The embodiment of the invention provides a data storage method and device and a data obtaining method and device. The data storage method is applied to storage servers with solid state disks. The datastorage method comprises the steps of obtaining video data; determining whether the type of the video data is an alarm type or not; storing the video data to the solid state disks if the type of thevideo data is the alarm type and sending alarm data notice information to a management server corresponding to a target storage server group; obtaining response information which is replied by the management server and comprises target identification information, wherein the target identification information is the identification information of the preset number of storage servers except the storage server sending out the notice information in the target storage server group; and sending the video data to the storage servers with the target identification information. According to the scheme,on the premise of ensuring the security of valuable video data, the access efficiency of the valuable video data is improved, and moreover, the read / write speed of the valuable video data is improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a data storage and acquisition method and device. Background technique [0002] In the field of video surveillance technology, video cloud storage systems are widely used. For video cloud storage systems, in order to ensure the security of video data, data storage redundancy backup schemes are very common. Specifically, the solution refers to: after the front-end equipment collects any video data, the video data will be backed up to the solid state disks of at least two storage servers in the video cloud storage system, so that even if one storage server fails, The rest of the storage servers can also operate normally, so the video data can still be accessed normally, thereby better ensuring the security of the video data. [0003] However, there are certain problems in the above-mentioned scheme: for the video data stored in redundant backup, only a small part thereof...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain problems in the above-mentioned scheme: for the video data stored in redundant backup, only a small part thereof is valuable, and the remaining useless video data will take up a large amount of storage space, which will seriously affect the Efficient access to valuable video data

Also, SSDs have poor performance, which can limit the speed at which valuable video data can be read and written
