Overview - Database Backup - Alibaba Cloud Documentation Center

Database Backup (DBS) allows you to back up data and log files across regions. This topic describes the geo-redundancy solutions provided by DBS to back up different types of databases.

Pricing

You can configure cross-region backups in the ApsaraDB RDS console or in the DBS console. Billable items vary based on the configuration methods.

If you configure cross-region backup tasks in the ApsaraDB RDS console, you are charged for backup storage, traffic for cross-region data transmission, and traffic that is generated when you download backup files over the Internet. For more information, see the following references corresponding to each database engine:
- For information about how to configure cross-region backup tasks for ApsaraDB RDS for MySQL databases that use local SSDs, see Use the cross-region backup feature.
- For information about how to configure cross-region backup tasks for ApsaraDB RDS for SQL Server databases that use standard SSDs or enhanced SSDs (ESSDs), see Use the cross-region backup feature.
- For information about how to configure cross-region backup tasks for ApsaraDB RDS for PostgreSQL databases that use local SSDs, see Use the cross-region backup feature.
If you configure cross-region backup tasks in the DBS console, you are charged for the used resources of DBS instances and backup storage. For more information, see Billing overview.

MySQL or MariaDB databases

Engine type	Recommended solution	Description	Benefit
ApsaraDB RDS for MySQL databases	We recommend that you run cross-region backup tasks in ApsaraDB RDS.	You can configure cross-region backup tasks in the ApsaraDB RDS console. For more information, see Use the cross-region backup feature.	High security: Data is transmitted across regions over virtual private clouds (VPCs). This enhances data security. High performance: Data backup operations can be performed at a high rate. Ease of use: To perform cross-region backup operations, you need to only enable the cross-region backup feature in the ApsaraDB RDS console.
ApsaraDB RDS for MariaDB databases PolarDB for MySQL databases Self-managed MariaDB databases Self-managed MySQL databases with hundreds of gigabytes of data MySQL databases that are deployed on third-party cloud platforms	We recommend that you run logical backup tasks in DBS.
