Abstract

The invention discloses an Oracle timely mounting and restoring system based on timing backup, which comprises a backup module, a backup storage module, a snapshot generation module, a mount recoverymodule module and a replica mounting module. The backup module is used to back up the original data of a database, and to back up the newly added data in a database server, the backup storage module is used for storing the data of the original backup and the newly added backup to a database log server. The snapshot generation module is configured to generate a copy of the backup at the network memory storage end after each backup is finished. The mount recovery module is used for selecting a time point when the data needs to be recovered, and rolling back the network memory to the replica corresponding to the time point, and the replica mounting module is used to mount a replica of the mount recovery module rollback to the database log server. The invention can simplify the data use flow,improve the timeliness of the user using the service data, improve the data use efficiency, and achieve the effect of simplicity and ease of use.

Description

technical field [0001] The invention relates to the technical field of database backup and disaster recovery, in particular to an Oracle timely mount recovery system and method based on timing backup. Background technique [0002] In the field of database backup disaster recovery, there are two mainstream data protection methods in the market: backup and CDP. [0003] Data backup refers to the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by system operation errors or system failures. [0004] CDP (Continuous Data Protection, continuous data protection), which uses the method of recording benchmark data and incremental data logs, and then indexing the logs, allows users to see any copy of historical data in a short period of time. [0005] Whether it is CDP protection or traditional scheduled backup, data backup and recovery are ultimately inseparable, but the ef...
