Embodiment Construction

[0013] 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.

[0014] figure 1 It is a data backup system based on an in-memory database according to an embodiment of the present invention, including: an in-memory database 10, an agent module 20, and a backup manager 30, wherein,

[0015] The backup manager 30 is configured to issue a backup strategy to the agent module 20, wherein the backup strategy includes data to be backed up (can be data in one / multiple data tables);

[0016] Agent (Agent) module 20 is used to access the above-mentioned data to be backed up in the memory database 10 by the API (Application Programming Interface, application programming interface, also called application programming interface) provided by the memory database 10 according t...

Abstract

The invention discloses data backup system and method based on a memory database. The system comprises the memory database, a proxy module and a backup manager, wherein the backup manager is used for issuing a backup strategy to the proxy module, wherein the backup strategy contains data that needs to be backed-up; and the proxy module is used for accessing data in the memory database according to the backup strategy through an application program interface (API) provided by the memory database and transmitting the accessed data into the backup manager so as to carry out backup. The invention avoids the problems of the interference on the saving operation of the memory database and the occupying of read-write (IO) resource of the memory database and realizes the backup to designated object data.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data backup system and method based on an in-memory database. Background technique [0002] At present, in the research on the backup process of the memory database, there are mainly the following two methods for data backup in the memory database: the method of copying by using the stored file and the method of exporting by using the memory data. [0003] Among them, the backup method of copying the stored files is adopted. Since the copying process involves the occupation of the stored files in the memory database (exclusiveness of copying), the copying of the stored files during the backup process will cause a loss to the normal memory database. Interference with the save process. Using the backup method of in-memory data export (similar to the method of saving as), this will occupy a large amount of system memory resources in a short period of time, resulting in a decreas...
