The invention provides a video backup method and a video backup device. The method is applied to BM, and comprises the steps of receiving a backup task, acquiring movement amount records of the backup task within a specified time period; combining two adjacent records between which the interval time is less than a first numerical value in the movement records as one record, thus acquiring aggregated movement records; and reading a section of the video within a start-stop period corresponding to each record in the aggregated movement records, building a backup file in backup IPSAN equipment, and writing each read video section into the backup file. According to the method and the device provided by the invention, the time fragments of movement records are aggregated into continuous and large time fragments, the section of the video within the start-stop period corresponding to each record in the aggregated movement records are written into the same backup file, so that appearance of a lot of fragmented files in a few or tens of seconds can be avoided, a utilization rate of backup space resources is improved, a user does not need to frequently open the file when accesses to the video, and thus video access efficiency is improved.
Description
technical field [0001] The present application relates to the field of storage technology, and in particular to a video backup method and device. Background technique [0002] In the video surveillance industry applications such as public security and parks, there are the following backup requirements for the original video: For some important time period videos selected by the user (for example: video recordings related to the time period of the camera involved in major public security cases), it is necessary to perform backup . That is to say, this part of the video is transferred from the original storage space and stored in the dedicated storage space for backup, thus effectively preventing the video from being overwritten and the record being lost due to limited original storage resources. [0003] In the related technology, the camera uses the moving object analysis algorithm to extract the movement data of each frame from the collected video, and reports the movement...
