Abstract

The invention discloses a data backup method and device and a database remote backup system, the data backup method is suitable for a main library of the database remote backup system, the main library and a standby library communicate through a mirror image communication process, and the data backup method comprises the following steps: receiving a first identifier of a first pre-writing log of the standby library; obtaining an identifier increment of a second identifier of a second pre-written log relative to the first identifier according to the first identifier, wherein a second preset logis stored in a main library; and sending a second pre-written log increment corresponding to the identifier increment to the standby library, so that the standby library stores the modification datacorresponding to the second preset log increment in the main library according to the second preset log increment. The preset log increment in the main library relative to the preset log increment inthe standby library is sent to the standby library, the main library and the standby library form the internal logic of the database remote backup system to back up the modified data, and backup can be completed without disconnecting the service.

Description

technical field [0001] The present disclosure relates to the technical field of big data, in particular to a data backup method, device and interactive system. Background technique [0002] Information systems play an increasingly important role in modern society, and most information systems rely on database systems to manage and store data. The reliability requirements of the system are also getting higher and higher, and the reliability of the database has naturally received high attention. Now the database system realizes the internal reliability of the system, and the backup in the system is already a basic requirement. However, this can only guarantee the security of the information system to a certain extent, and cannot solve the threat of some natural disasters to the data of the detailed information system, such as fire, earthquake and other threats to the reliability of the database. Off-site backups are established in different geographical areas, which can solv...
