Database backup method and device
ActiveCN106445738AImplement backupImprove securitySpecial data processing applicationsRedundant operation error correctionReal time servicesDatabase backup
The invention discloses a database backup method and device. Data tables in a database are classified into historical data tables and real-time service data tables; full-volume backup is conducted on the service data tables; incremental backup is conducted on the historical data tables; the backed-up service data tables and historical data tables are stored in a medium to complete backup of the database. Due to the fact that historical data in a large mysql database occupies a large amount of storage space and real-time service data is less, the historical data tables and the real-time service data tables are backed up in a separated mode, the data volume each time of backup can be decreased, the backup time and recovery time can be shortened, and the backup speed can be improved. It is thus clear that backup of the database in a large mysql database scene is rapidly achieved, the backup recovery time is decreased, backup file space occupation is decreased, and the backup recovery efficiency and the safety guarantee capability of the database are improved.
