Intelligent ftp backup video recording method and system

Abstract

The invention provides a smart FTP (File Transfer Protocol) backup video recording method and system. The smart FTP backup video recording method includes that a backup object plan module chooses FTP backup video recording characteristics of a hard disk video; a backup object memorizing module makes backup marks for video sections conforming to FTP backup video recording characteristics after recording a video section in each channel of the hard disk video; the video section with backup marks are searched according to the search conditions; a network idle defining module judges whether a certain channel of the hard disk video is already provided with idle backups, if so, when the network idle defining module monitors that the current network bandwidth of the channel is idle, an FTP backup functional module uploads a video section searched from the channel to an FTP server for backup; if not, the FTP backup functional module uploads a video section searched from the channel to an FTP server for backup. The smart FTP backup video recording method and system can achieve low-cost, flexible, efficient, reliable, fast and convenient video backup.

Description

technical field [0001] The invention relates to an intelligent FTP backup video recording method and system. Background technique [0002] The backup methods of existing digital hard disk video recorders mainly contain the following several types: configure redundant disks, use local hard disks or network storage media such as network-attached storage (NAS, Network Attached Storage), Internet Small Computer System Interface (iSCSI: Internet Small Computer System Interface) disk as a redundant disk; Redundant Arrays of Independent Disks (RAID, Redundant Arrays of Independent Disks) technology combines multiple independent physical hard disks in different ways to form a logical disk, thereby providing higher storage than a single hard disk. Performance and technology to provide data redundancy; external U disk mode. Among them, NAS is a mechanism that uses special equipment directly connected to the network medium to realize data storage. These devices are assigned IP addres...

Problems solved by technology

The disadvantage of this solution is that the backup time and backup cycle are limited by the configuration, which is not flexible enough, which is manifested in two aspects

First, when the single hard disk DVR device is backed up to an external storage device, because the storage space is usually small and the storage device is easy to be full, it is necessary to manually replace the storage device frequently; Elasticity, when the network load of the hard disk video recorder is high, it will affect all remote operation services such as remote preview and remote playback, and when the backup fails due to network failure and other problems, there is no resuming mechanism

[0007] Whether it is manual backup or scheduled backup, the lack of on-the-spot response is manifested in the following: during manual backup, if the backup requirements have been met but the external backup device is not in place, you must first remember the characteristics of the backup data before obtaining the backup device, which is not enough Humanize

And scheduled backup also shows that the memory is insufficient, or the memory is limited to the current day. When one day is limited by the backup conditions, it will not be considered to back up the original plan to be backed up but not backed up on the next day, and the backup failure is insufficiently considered. The integrity of the backup data is not guaranteed

When encountering an abnormal shutdown during the backup process, the previous method usually restarts the backup, resulting in reduced efficiency, or even giving up the backup, resulting in incomplete data
