Billing
When you use the backup download feature on an RDS instance that uses cloud disks, two charges may apply: Internet traffic fees and backup set conversion fees.
Traffic fees
You can download the backup files of an RDS instance over an internal network or the Internet regardless of the storage type of the RDS instance.
| Download method | Charge |
|---|---|
| Internal network | Free |
| Internet | Free for the first 500 GB per instance per month; pay-as-you-go for excess usage, billed daily |
For pay-as-you-go pricing for Internet traffic, see Network traffic fees.
Example: If you download 700 GB in a month, only the 200 GB that exceeds the 500 GB free quota is billed.
How charges are triggered:
Charges apply only after a download task completes and you download the backup file using the URL. If a task is in progress or has failed, the download URL is not available and no Internet traffic charge is incurred.
Cloud disk vs. local disk download behavior:
| Instance type | Download process | When traffic is charged |
|---|---|---|
| Cloud disk (snapshot backup) | The system converts the snapshot backup file and generates a download task. The URL is available only after the task completes. | When you download the file using the URL after task completion |
| Local disk (physical backup) | No conversion is needed. The system provides the download URL directly. | When you download the file using the URL |
Monitor your traffic usage:
In the ApsaraDB RDS console, go to your instance details page:
-
Click the instance ID to open the instance details page.

Go to Basic Information.

In the Usage Statistics section, check the Backup Downloads parameter to view the volume of Internet traffic consumed for backup downloads.
Reduce costs with a network plan:
Purchase a subscription network plan to offset Internet traffic fees. Higher-capacity plans offer greater discounts. For details, see Use network plans.
Backup set conversion fees
The Advanced Download feature converts snapshot backup files into CSV (with or without headers), SQL, or Parquet format before download. Each conversion is charged with no free quota.
| Region | Unit price |
|---|---|
| Public cloud | USD 0.03125 per GB |
If a conversion task fails, no backup set conversion fee is charged.
