This topic describes the backup storage pricing of an ApsaraDB RDS for MySQL instance.

Backup storage fee

If the total size of the backup files of your RDS instance does not exceed the free quota for backup storage, no fees are charged. For more information, see View and manage the size of backup files for an ApsaraDB RDS for MySQL instance. If the total size exceeds the free quota, you are charged an hourly fee for the amount of excess backup storage that you use. The hourly fee is calculated by using the following formula:

Hourly fee for backup storage = (Total size of backup files - Free quota) × Unit price

  • Total size of backup files: the total size of data backup files and log backup files. You can log on to the ApsaraDB RDS console, go to the Basic Information page of your RDS instance, and then view the free quota in the Usage Statistics section of the page.
  • Free quota: a specific amount of storage that is allocated to store the backup files of your RDS instance. This amount of storage is free of charge. If your RDS instance uses standard SSDs or enhanced SSDs (ESSDs), the free quota is 200% of the storage capacity that you purchased for your RDS instance. If your RDS instance uses local SSDs, the free quota is 50% of the storage capacity that you purchased for your RDS instance. The free quota is measured in GB. You can only round the free quota up to the next integer. You cannot round the free quota down. You can log on to the ApsaraDB RDS console, go to the Basic Information page of your RDS instance, and then view the free quota in the Usage Statistics section of the page.
  • Unit price: The unit price varies based on several factors. The following table describes the factors.
    Storage type Unit price for backup files that are stored for up to 730 days (USD per GB) Unit price for archived backup files that are stored for more than 730 days (USD per GB)
    Standard SSD or ESSD 0.00004 The unit price varies in different regions:
    • Japan (Tokyo), India (Mumbai), Singapore (Singapore), Australia (Sydney), Indonesia (Jakarta), and Philippines (Manila): 0.000034
    • China (Hong Kong): 0.000031

    • Other regions: 0.000025
    Local SSD 0.00020
Note The backup storage fee can be deducted from your Database Backup (DBS) storage plan. For more information, see Storage fees.

Usage notes

The backup storage fee varies based on the total size of backup files. Backup files do not consume the storage capacity of your RDS instance. Therefore, the backup storage fee is not affected by the storage usage.

When you analyze the backup storage fee, you must check the total size of backup files. You do not need to check the storage usage.
