Embodiment Construction

[0027] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0028] In this embodiment, a data synchronization method is provided, figure 1 is a flow of a data synchronization method according to an embodiment of the present invention Figure 1 ,Such as figure 1 As shown, the process includes the following steps:

[0029] Step S102, synchronizing the historical data of the master device before data synchronization to the backup device;

[0030] Step S104, judging whether there is a data change during the operation of the active device during the period of the historical data synchronization between the active device and the backup device;

[0031] Step S106, if the judgment result is yes, synchronize the changed data to the backup device.

[0032] Through...

Abstract

The invention discloses a data synchronization method and device; the method comprises the following steps: synchronizing history data of a main device to a standby device before data synchronization; determining whether the main device has data change or not in a running process when the main device and the standby device perform history data synchronization; if yes, synchronizing the changed data to the standby device. In the prior art, when a host and a spare machine are not simultaneously powered up, the host needs to be shut down when the host and spare machine need data synchronization; the novel data synchronization method and device can solve the said problems, so the host system needs not be shut down in data synchronization, thus improving system stability.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data synchronization method and device. Background technique [0002] In the existing database system, in order to increase the reliability of the system, it is generally necessary to add one or more standby databases to the main database. When the primary database is abnormal, it will switch to the standby database to provide relevant data services through the switching mechanism. [0003] A common application scenario is that the active and standby databases go online at the same time. In this case, the initial data of the active and standby databases is consistent, and the data of the subsequent host is changed, and the increment is synchronized to the standby to ensure data consistency. In another case, the main machine has been online before, has historical data, and the standby machine is newly online. You can copy the database file from the main machine, and then impo...
