Abstract

The invention discloses a protection method of data security and a device. The method comprises: an array adapter is arranged in a digital video recorder, the array adapter is connected with the digital video recorder through an expansion bus, and the digital video recorder is provided with a plurality of hard disks. The method further also comprises: the array adapter receives the data from the digital video recorder through the expansion bus when the digital video recorder needs to save the data, and calculates the save location of the data in the hard disks; and the data is saved in the calculated save location in a disk array mode. According to the invention, the data can be saved in the disk array mode, thereby avoiding the data loss of all the hard disks due to the fault of one hard disk, and effectively protecting the data in the hard disks.

Description

technical field [0001] The invention relates to the technical field of digital hard disk video recorders, in particular to a method and device for protecting data security. Background technique [0002] Digital hard disk video recorder (DVR) is a high-tech product combining computer technology, network technology, digital video technology and traditional video and security technology. Remote monitoring, bank security monitoring, building intelligence, home anti-theft monitoring and other fields have broad market prospects. [0003] At present, there are usually multiple built-in hard disks in a DVR, and there can be up to 8 built-in hard disks. When recording information, no matter how many hard disks are built in, the video data is saved in the way of sequential writing. With the continuous increase of hard disk capacity, the probability of video data loss caused by a single hard disk failure is also increasing simultaneously. In this way, any hard disk failure will dest...
