Database Backup (DBS) provides an emergency disaster recovery feature to automatically obtain backup sets and generate snapshots. A DBS sandbox instance can be generated in a short period of time.
Background information
DBS provides a complete sandbox solution for MySQL databases based on copy data management (CDM). You can use the sandbox feature of DBS to create a sandbox instance to restore data in a backup set within a short period of time. Read and write operations are performed within sandbox instances and do not affect source databases. You can perform various operations within sandbox instances, such as data restoration, recovery drills, development and testing, query and analysis, and emergency disaster recovery. For more information, see Overview.
Billing
- ApsaraDB RDS provides the physical backup of ApsaraDB RDS instances and charges you backup fees. For more information, see Backup storage pricing of an ApsaraDB RDS for MySQL instance.
- After you enable the sandbox feature, DBS automatically synchronizes the data to be restored to the sandbox storage and generates multiple snapshots for the backup data. The snapshots are stored in the sandbox storage and can be directly used to create sandbox instances. DBS charges you sandbox storage fees based on the volume of the data stored in the sandbox storage. For more information, see Sandbox storage fees.
- After you create a sandbox instance for emergency disaster recovery, DBS charges you sandbox instance fees based on the specifications and usage duration of the sandbox instance. If you have not created sandbox instances for emergency disaster recovery, you are not charged sandbox instance fees. For more information, see Sandbox instance fees.
Prerequisites
- An ApsaraDB RDS for MySQL instance with local SSDs is created. At least one physical backup is complete in the ApsaraDB RDS console. For more information, see Enable automatic backups for an ApsaraDB RDS for MySQL instance.
- The RDS instance resides in one of the following regions: China (Beijing), China (Shanghai), China (Hangzhou), China (Shenzhen), China (Zhangjiakou), China (Chengdu), China (Hohhot), China (Ulanqab), China (Heyuan), China (Hong Kong), Indonesia (Jakarta), Malaysia (Kuala Lumpur), Australia (Sydney), Germany (Frankfurt), China East 1 Finance, Japan (Tokyo), US (Silicon Valley), Singapore (Singapore), US (Virginia), and India (Mumbai).
- Transparent Data Encryption (TDE) is disabled for the ApsaraDB RDS for MySQL instance. For more information about TDE, see Configure TDE for an ApsaraDB RDS for MySQL instance.
Enable the sandbox feature
After you enable the sandbox feature, DBS synchronizes the data to be restored to sandbox storage. Then, you can create a sandbox instance for emergency disaster recovery.

What to do next
You can obtain the endpoint of the sandbox instance in the ApsaraDB RDS console and connect to the endpoint by using the corresponding client. You can also connect to the sandbox instance by using Data Management (DMS) or ECS. For more information about DMS and ECS, see Use DMS to access sandbox instances and Use ECS to access sandbox instances.
