Abstract
The invention discloses a backup and recovery method and a backup and recovery device for high-availability server databases in offline places. The backup method comprises the following steps: distributing a unique identity ID for each offline place; performing complete logic backup on the data of each offline place, wherein the backup information includes the meta information of the place; compressing all the backup information and then storing the backup information in an online database server; adding a meta title into the data information and uploading to a file system of a cloud terminal; performing differential backup on the changed data of each offline place, wherein the backup information includes the meta information of the place. According to the backup and recovery method disclosed by the invention, the catalog information of the cloud terminal is utilized to distribute the storage space of the cloud terminal and position data storage paths of a plurality of offline places. According to the invention, the problem of server resource waste caused by the uploading of the data of the offline places through the cloud terminal in the prior art can be solved. The purpose of realizing the backup and recovery of high-availability efficient database is achieved by intelligently recovering a fault database through the incremental backup of high-volume database data to a cloud server cluster.
