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 run cross-region backup tasks in ApsaraDB RDS, 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:
  • If you run cross-region backup tasks in DBS, you are charged for the used resources of DBS instances, backup storage, and traffic that is generated when you download backup files over the Internet. The used DBS resources can be billed based on the subscription billing method or pay-as-you-go billing method. For more information, see Billing overview.
