For example, the program may be software, or a medium storing a related computer program, such as a usb disk; or the apparatus may be a physical device, such as a chip, a smart terminal, a computer, a server, etc., integrated with or having an associated computer program installed thereon.
In one example, S101 is further preceded by: receiving a cloning task sent by a platform, wherein the cloning task is sent by the platform according to a cloning request of a user, and the cloning request comprises real equipment under a source cluster designated by the user and the current cluster for backup; and adding virtual equipment corresponding to the real equipment under the current cluster according to the cloning task, and storing the mapping relation between the real camera and the virtual equipment.
In combination with the scenario example, cloned virtual devices are added and a mapping relationship between the virtual devices and the real devices is established before backup is performed. And when the backup task is executed, executing the stream data backup of the corresponding real device according to the virtual device and the mapping relation.
As an implementation, as shown in fig. 3, fig. 3 is an example of a cloning device. Reporting information of real equipment included in a cloning request of a user to a platform, generating a cloning task by the platform according to the cloning request and the reported information, and sending the cloning task to a current cluster, wherein the current cluster adds virtual equipment corresponding to the real equipment according to the real equipment information included in the cloning task. The backup flow of the virtual equipment is consistent with that of the real equipment, and the operation codes of the corresponding real equipment can be multiplexed by adding the virtual equipment.
As another implementation manner, only the corresponding virtual device needs to be added according to the real device specified by the user, and the user considers that the unnecessary real device can not initiate the cloning task, so that flexible backup is realized.
Based on the above embodiment, the cloned virtual device is added for stream data backup, so that multiplexing of resources can be realized, and resources are saved.

Therefore, when executing cloning task, by verifying information of real device, adding error virtual device can be avoided, problem can be found early, and error in executing stream data backup can be avoided.
In combination with a scenario example, the real device has the condition of updating iteration, and when a certain real device is removed or replaced, the real device information contained in the user request cannot be found.
Based on the above embodiment, by verifying the real device, erroneous cloning can be avoided, thereby improving the effectiveness of data backup.
In one example, S202 includes: sending a pull stream address acquisition request to the source cluster; receiving a pull stream address of the real equipment returned by the source cluster; the source cluster acquires a request according to the streaming address, and extracts streaming data of real equipment corresponding to the target equipment; and establishing a real-time streaming session between source clusters of the real equipment corresponding to the target equipment in the current cluster based on a real-time streaming protocol according to the streaming address of the real equipment.
As one way of implementation, fig. 4 is an example of setting up a real-time streaming session, as shown in fig. 4. And establishing a pull stream address acquisition request according to the information of the real equipment in the backup task. The source cluster extracts the pull stream address from the stream data of the real device, and returns the pull stream address to the current cluster. The current cluster establishes a real-time streaming session based on the pull stream address and the source cluster. The real-time streaming session is used to transmit real-time streaming data of the real device.
Based on the above embodiment, by establishing the real-time streaming session, real-time streaming data can be transmitted in real time, and video streaming data of real equipment can be sent to the current cluster for backup at the first time, so that the security of the streaming data is improved.
In one example, the backup task includes a backup period; s203 includes: in the backup period, receiving stream data sent by the real device corresponding to the target device through the real-time stream transmission session; and storing the received streaming data of the real equipment in a local disk under the current cluster until the backup period is over, and disconnecting the real-time streaming session.
As one way of implementation, the user may specify a backup period, for example, for a monitored video, a recorded video of a daytime period in which the traffic is large is more important, and the daytime period is taken as the backup period. In the backup period, stream data of the real device is sent to the current cluster in real time, and in the non-backup period, the real-time stream transmission session is closed, and stream data of the real device is not sent to the current cluster.
Based on the above embodiments, by designating the backup period, the period for executing the backup task can be flexibly selected according to the specific needs of the user.
As illustrated in fig. 5, fig. 5 is an example of performing a backup task. The current cluster starts a backup task, a request is obtained to a source cluster in a pulling way, the source cluster extracts a pulling address from stream data of real equipment, the pulling address is returned to the current cluster, the current cluster establishes a real-time stream transmission session according to the pulling address and the source cluster, the source cluster sends a real-time stream to the current cluster through the real-time stream transmission session, the current cluster receives the real-time stream and stores the real-time stream in a local disk until the backup time is over, and the real-time stream transmission session is closed.

In combination with the scenario example, when the disk under the source cluster can work normally, the backup data used by the user is called from the disk under the source cluster, and when the disk under the source cluster is damaged and cannot work normally, the backup data used by the user is called from the current cluster. It will be appreciated that it is relatively quick to obtain backup data of the streaming data of the source cluster from the disks under the source cluster.
Based on the above embodiment, the source cluster and the disk of the current cluster are completely independent, and when the disk of the source cluster cannot be used, the disk of the current cluster can work normally, so that the security of backup stream data is improved.
