Abstract

The embodiment of the invention discloses a DVR (Digital Video Recorder) as well as data backup and recovery method and system thereof, which are applied to a monitoring system comprising a backup DVR and a plurality of video DVRs, wherein the backup DVR is connected with the video DVRs. The method comprises the following steps of: when the backup DVR detects abnormal video DVRs, switching the videos of the abnormal video DVRs to the backup DVR; carrying out data backup on the abnormal video DVRs through a video source by the backup DVR; when the detected abnormal video DVRs return to normal, stopping the data backup and transmitting the backed up data to the abnormal video DVRs; and carrying out data recovery by the abnormal video DVRs according to the backed up data to obtain a complete data source. By applying the invention, the recovery of complete data can be automatically carried out according to the backup data transmitted by the backup DVR, thereby the operation complexity is reduced.

Description

technical field [0001] The present application relates to the technical field of digital monitoring, in particular to a DVR (Digital Video Recorder, digital video recorder) data backup and recovery method, system and DVR. Background technique [0002] DVR is a monitoring device that can record video and audio data through a data hard disk.
