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

MySQL or MariaDB databases

Database type Recommended solution Description Benefit
  • ApsaraDB RDS for MySQL databases with local SSDs

Perform cross-region backups in the ApsaraDB RDS console.

You can perform backups across regions in the ApsaraDB RDS console. For more information, see Enable cross-region backups for an ApsaraDB RDS for MySQL instance.
  • Security: Backup data is transmitted across regions over VPCs. This enhances data security.
  • Fast data backup
  • Ease of use: To perform cross-region backups, enable the cross-region backup feature in the ApsaraDB RDS console.
  • ApsaraDB RDS for MySQL instances with standard or enhanced SSDs
  • ApsaraDB RDS for MariaDB TX databases
  • PolarDB for MySQL databases
  • Self-managed MariaDB databases
  • Self-managed MySQL databases with hundreds of gigabytes in size
  • MySQL databases from other cloud service providers

Perform logical backups in the DBS console.

You can use the multi-level storage pool feature of DBS to dump data backups across regions over VPCs. For more information, see Use the multi-level storage pool feature to implement geo-redundancy.

Note The multi-level storage pool feature is in public preview. We recommend that you try this feature.
  • Security: Backup data is transmitted across regions over VPCs. This enhances data security.
  • Fast data backup
  • Flexibility: DBS allows you to configure the backup cycle in a more flexible manner.

    For example, you can configure a backup policy to perform backups within a region on a daily basis and dump the backups to other regions every month.

You can back up databases across regions over the Internet. For more information, see Implement geo-redundancy for a self-managed database.
  • Internet access to databases required
  • Cost-effectiveness
  • Self-managed MySQL databases with terabytes in size
