Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a national stage of International Application No. PCT/CN2021/109011, filed on Jul. 28, 2021, which claims priority to Chinese Patent application No. 202010740387.X, filed on Jul. 28, 2020. Both of the aforementioned applications are incorporated herein by reference in their entireties. TECHNICAL FIELD Embodiments of this disclosure relate to the storage field, and more specifically, to a backup management method and system, a device, and a medium. BACKGROUND With development of a terminal device such as a mobile phone, a tablet computer, a television, and an in-vehicle infotainment system, dependence of a user on the terminal device increasingly increases, and a size and importance of data stored by the user in the terminal device (for example, an image, a video, audio, or application data) increasingly increase. In this case, when storage space of the terminal device is insufficient or the terminal device is faulty, lost, replaced, or the like, how to permanently store user data in the terminal device becomes a challenge. Conventionally, the user data in the terminal device may be backed up in another storage device, to expand storage space of the terminal device, or the user data is restored by using another storage device when the terminal device is faulty, lost, replaced, or the like. However, such a backup operation is manually performed by the user to different degrees. However, the user may sometimes forget to do a backup or cannot do a backup in a timely manner. In addition, performing such a backup operation may be difficult for some users, reducing user experience. SUMMARY Embodiments of this disclosure provide a backup management solution, to implement automatic backup of data, and improve backup efficiency. According to a first aspect of this disclosure, a backup management method is provided. The method includes: A network device is connected to a terminal device; the network device determines whether a backup task associated with the terminal device exists, where the backup task is used to store to-be-backed-up target data in the terminal device in a destination storage device, and the destination storage device is connected to the network device; and if the network device determines that the backup task exists, the network device indicates the terminal device to start the backup task, to store the target data in the destination storage device. In this manner, the network device can automatically detect whether the backup task exists, and automatic backup of data in the terminal device is implemented when the backup task exists, without a need to perform manual intervention, to improve backup efficiency and user experience. In some embodiments, after the network device indicates the terminal device to start the backup task, the method further includes: The network device receives destination address information and the target data that are sent by the terminal device; the network device finds the destination storage device based on the destination address information; and the network device sends the target data to the found destination storage device. In this manner, the network device can search for the destination storage device based on the destination address information from the terminal device, and the terminal device does not need to have a capability of searching for the destination storage device. Therefore, stability of a backup system can be improved. In some embodiments, the destination address information includes an identifier of the destination storage device; or the destination address information includes an identifier of the destination storage device and an identifier of a destination directory in the destination storage device. In this manner, the destination storage device and the destination directory can be easily determined. In some embodiments, the indicating the terminal device to start the backup task includes: The network device sends an application start request to a cloud server of the terminal device, to indicate the cloud server to start a backup application in the terminal device; or the network device directly sends an application start request to the terminal device, to indicate the terminal device to start a backup application. In this manner, the network device can indicate the cloud server to start the backup application or the network device automatically starts the backup application in the terminal device, without a need to perform manual intervention, to start the backup task. Therefore, backup efficiency and user experience are improved. In some embodiments, that the network device finds the destination storage device based on the destination address information includes: The network device determines an address of the destination storage device based on the destination address information and device information of at least one candidate storage device connected to the network device.
