Abstract

Embodiments of the invention provide a database recovery method and apparatus. The method comprises the following steps of determining to-be-recovered data in response to a database recovery instruction; identifying a physical backup file associated with the to-be-recovered data; if a data quantity of the physical backup file is greater than a preset threshold, obtaining first data needed for recovering the to-be-recovered data from a logic backup file associated with the to-be-recovered data; and according to the first data and a backup log corresponding to the first data, performing recovery processing on the to-be-recovered data. According to the method and the apparatus provided by the embodiments of the invention, the data in a database can be quickly recovered.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a database recovery method and device. Background technique [0002] A database is a warehouse that organizes, stores and manages data according to its data structure. When a hardware or software failure occurs in the database, data may be lost, and it is necessary to perform a recovery operation on the database. [0003] In the prior art, the database is generally physically backed up periodically, and when the database needs to be restored, the database can be restored to a specified time point according to the data of the physical backup. The recovery speed of this database is relatively slow. Contents of the invention [0004] Various aspects of the present application provide a database recovery method and device, which are used to improve the speed of data recovery in the database. [0005] The embodiment of the present application provides a database re...
