ApsaraDB RDS provides various disaster recovery solutions to protect your data.
Data backup and restoration
- By default, ApsaraDB RDS provides the data backup feature. Automatic backup and manual backup are supported. You can specify a cycle for automatic backups and initiate backup tasks at any point in time based on your business requirements. For more information, see Backup and restoration.
- By default, ApsaraDB RDS allows you to restore data from backup files or restore data to a specific point in time. In most cases, you can restore data to any point in time within seven days to a temporary or cloned RDS instance. After the data is verified, you can migrate the data back to the primary RDS instance to complete data backtracking. For more information, see Backup and restoration..
|RDS Basic Edition||
|RDS High-availability Edition||Your database system consists of a primary RDS instance and a secondary RDS instance.
The RDS instances work in active-active mode to ensure high availability. This edition
is suitable for more than 80% of business scenarios. When the primary RDS instance
fails, the workloads are switched over to the secondary RDS instance within seconds.
The switchover process is transparent to the application. When the secondary RDS instance
fails, ApsaraDB RDS automatically creates another secondary RDS instance to ensure
the high availability of your database system.
|RDS Cluster Edition||Your database system consists of a primary RDS instance and a secondary RDS instance.
You can create up to seven read-only RDS instances for the primary RDS instance to
scale out the read capability of the cluster. The data of the secondary RDS instance
and the data of all read-only RDS instances are synchronized from the primary RDS
instance. RDS Cluster Edition provides the same high availability as RDS High-availability
Edition. Read-only RDS instances can be deployed in zones other than the zones of
the primary RDS instance and the secondary RDS instance.
