Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] refer to figure 1 , figure 1 It is a schematic structural diagram of the data switching server of the hardware operating environment involved in the solution of the embodiment of the present invention.

[0039] like figure 1 As shown, the data switching server may include: a processor 1001 , such as a CPU, a communication bus 1002 , a user interface 1003 , a network interface 1004 , and a memory 1005 . Wherein, the communication bus 1002 is used to realize connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. Optionally, the network interface 1004 may include a standard wired interface and a wi...

Abstract

The invention discloses a data switching method, device, server and system and a storage medium. The method comprises the following steps of: firstly searching target backup data corresponding to a switching time point; calculating data difference information between current backup data at the current moment and the target backup data; pushing the data difference information to a secondary serverto ensure that the secondary server generates and feeds back a corresponding data request according to the data difference information; and finally receiving the data request fed bac k by the secondary server, searching difference data corresponding to the data request, sending the difference data to the secondary server to ensure that the secondary server carries out data coverage according to the difference data and data of the secondary server is switched back to the switching time point. According to the method, the condition that the secondary server synchronously writes in errors when aprimary server has logic errors is avoided, and the data correctness can be satisfied.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a data switching method, device, server, system and storage medium. Background technique [0002] With the rapid development of Internet technology, the requirements for business continuity and data reliability of servers are getting higher and higher. For important servers, a dual-machine hot standby design is adopted. In this solution, a standby server is required to synchronize data in real time. When a failure occurs, the standby server can normally take over the business, thereby ensuring business continuity. [0003] In the traditional dual-machine hot backup, the primary server and the standby server receive the same data at the same time, that is, the standby server exists as the mirror image of the primary server, and the mirror image is activated in time when a downtime occurs. Such a design scheme can solve the business continuity guarantee and enable t...
