High reliability

Last Updated: Mar 30, 2017

Hot standby

RDS uses hot standby, so if a physical server fails, the service is switched over in seconds without interruptions to application services.

Multi-copy redundancy

The data on the RDS server is stored on RAID, and backed up on OSS.

Data backup

RDS provides an automatic backup mechanism. You can set a backup schedule or initiate a temporary backup at any time.

Data recovery

Data can be recovered from a backup. Generally, data can be recovered within 7 days to a temporary RDS instance. After the data is verified, the data can be migrated back to the master RDS instance.
