High Reliability

Dual-host Hot Backup

RDS uses the hot standby architecture, in which failover upon fault occurrence takes only one minute.

Data Backups

RDS automatically backs up data every day and uploads backup files to Object Storage Service (OBS). The backup files are stored for 732 days free of charge and can be restored with just a few clicks. You can set a custom backup policy and create manual backups at any time.

Data Restore

You can restore data from backups or to any point in time during the backup retention period. In most scenarios, you can use backup data to restore data to the original DB instance or create a new DB instance at any time point within 732 days. After the data is verified, data can be migrated back to the primary RDS DB instance.
