Abstract

The invention discloses a database backup method and device. The method comprises the steps of detecting use condition of a database at a current moment, thereby obtaining a database use condition detection result; selecting a corresponding database backup mode according to the obtained database use condition detection result; and backing up the database according to the selected corresponding database backup mode. According to the method and the device, the technical problem that in related technologies, a backup operation and a normal read / write operation of the database are influenced mutually, thereby reducing the performance of the database, due to the fact that the database backup operation cannot be interrupted once the operation is started is solved.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a database backup method and device. Background technique [0002] Industries such as the Internet and finance have high requirements for data reliability. If data is lost due to unexpected downtime, the loss will be very heavy. For this reason, database administrators need to formulate detailed database backup strategies according to specific business requirements. [0003] In the related art, a technical solution for periodically performing a complete backup operation (ie, a full backup operation) on a database is provided. For example, a weekly or monthly full backup of the database. Usually, each full backup is a full copy of all data and applications in the database starting from a certain point in time. In practical applications, a disk is generally used to fully back up the entire system, including the backup system itself and all data. The biggest advantage of this backup ...
