Abstract

Embodiments of the present invention provide a hot standby method, device, and system, the method comprising: the primary device saves the first user information in the primary device to a local cache module of the primary device; further, The active device sends the first user information to the remote cache module of the first backup device according to the preset association information, so that when the first backup device detects that the active device fails, The first backup device obtains the first user information from the remote cache module of the first backup device and restores the first user information; it can be seen that the embodiment of the present invention can realize the hot backup function of multiple devices, In addition, the user information of the faulty device can be quickly restored, which improves the restoration efficiency.

Description

technical field [0001] Embodiments of the present invention relate to Internet technologies, and in particular to a hot backup method, device and system. Background technique [0002] In current network applications, in order to avoid the risk of network interruption due to single point of failure, for service nodes at the aggregation layer or edge layer, it is necessary to support dual-system hot backup between devices. [0003] In the existing dual-machine hot backup method, one active device and one backup device form a hot standby group; when a user in the active device goes online, the active device sends the corresponding user The information is saved in an external database shared with the backup device, so that when the main device fails, the backup device reads the user information from the external database and restores the user information of the user . [0004] However, in the dual-system hot backup method in the prior art, the time delay for restoring the user...
