A video data processing method is applied to a specified video cloud storage system in a video data processing system, the video data processing system further comprises a cloud center server in communication connection with the video cloud storage system, the specified video cloud storage system is a video cloud storage system which is found by the cloud center server from an un-failed video cloud storage system when a failed video cloud storage system exists, and the method comprises the following steps:

receiving a video data storage switching instruction sent by the cloud center server, wherein the video data storage switching instruction is sent by the cloud center server when a video cloud storage system with a fault exists, and the video data storage switching instruction comprises address information of video acquisition equipment corresponding to the video cloud storage system with the fault;

receiving and storing video data sent by video acquisition equipment corresponding to the address information;

sending a message of successful switching to the cloud center server so that the cloud center server sends a video data storage suspension instruction to the failed video cloud storage system; taking the time point of sending the video data storage switching instruction as a switching starting time point; storing the switching start time point, the identification information of the failed video cloud storage system and the identification information of the specified video cloud storage system as a switching record; and sending the switching record to the failed video cloud storage system so that the failed video cloud storage system stores the switching record.

12. A video data processing device is applied to a specified video cloud storage system in a video data processing system, the video data processing system further comprises a cloud center server in communication connection with the video cloud storage system, the specified video cloud storage system is a video cloud storage system which is found by the cloud center server from an un-failed video cloud storage system when a failed video cloud storage system exists, and the device comprises:
