Problems solved by technology

[0005] The disadvantage of the existing solution is obvious: the two servers can only be located in the same layer 2 network. If a disaster occurs in the layer 2 network such as a large-scale power outage or network outlet blockage, the service will stop immediately.
If the two mutually backup servers are located in two buildings with independent power supply capabilities, it is necessary to implement a dedicated line to connect the networks inside the two buildings, which requires more investment; if the path between the two servers supports MPLS L2VPN forwarding , the network requirements are higher

Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] figure 2 It is the flow chart of remote hot backup implementation provided by Embodiment 1 of the present invention. In this embodiment, the two servers are mutually backed up, such as figure 2 As shown, the specific steps are as follows:

[0041] Step 201: assign a real IP address to the two servers respectively, and assign a shared virtual IP address to the two servers, the two servers are respectively connected to an access router, and the two access routers are respectively connected to the home agent (HA , Home Agent) routes are reachable; configure the shared virtual IP address of the two servers as the listening address on each access router, and start the MIP function on the two access routers and HA.

[0042] Two servers are connected to different access routers respectively, and the two servers are located in diff...

Abstract

The invention discloses a method and apparatus for realizing allochthonous hot backup. In the invention, two servers having backup relationship share a virtue IP address and are respectively located in different access networks; each server is connected with Home Agent HA by different access routers; each access router is configured with the virtue IP address as intercept address; the method comprises: the two servers select the host and standby unit; the host carries the free address in broadcast of the local two network to analyze the ARP message; the access router connected with the host intercepts the message; the export address on the access router of the virtue IP address is registered on HA; HA transmits the message sending to the virtue IP address according to the export address of the access router of the virtue IP address. The invention improves the reliability of allochthonous backup.

Description

technical field [0001] The invention relates to the technical field of backup, in particular to a method and system for realizing remote hot backup. Background technique [0002] The failure of the server may be caused by various reasons, such as equipment failure, operating system failure, software system failure, access network failure, power supply system failure and so on. Generally, in the case of technicians on site, it may take 10 minutes or hours or even days to restore the server to normal. From practical experience, unless the server is simply restarted (the hidden danger may still exist), it often takes more than several hours to restore the server to normal. And if the technician is not on site, the time required to restore service is even longer. For some important systems, it is difficult for users to tolerate long-term service interruption. Therefore, it is necessary to use dual-machine hot backup to avoid long-term service interruption and ensure long-term...
