You are separately charged for each service of Database Backup. This topic describes the billable items and billing methods of Database Backup (DBS).
- Pay-as-you-go: Fees for DBS are calculated based on actual usage. You can complete the payment after a bill is generated. Fees are calculated based on the following formula: Fees = Actual usage × Unit price.
- Subscription: You can use resources only after you purchase resource plans. Resource plans are used to deduct fees incurred when you use resources during each billing cycle.
|Billable item||Description||Billing method|
|Backup fees||Fees incurred for the backup of data. You must purchase a backup schedule for each backup instance. You are charged for backup schedules based on the amount of data that is backed up. Backup and restoration performance, free quota for data backup, and billing methods vary based on backup schedule specifications. For more information, see Backup fees.||
|Storage fees||Fees incurred for the storage of backup data. You are charged for storage fees based
on the size and storage duration of the data stored in DBS.
Note If the stored data is compressed or the format of the stored data is optimized, the storage data size is smaller than the database disk space in most cases. For more information, see Data size.
|Network traffic fees (optional)||Fees incurred for network traffic generated during cross-region data backup initiated in the ApsaraDB RDS console. For more information, see Back up an ApsaraDB RDS for MySQL instance across regions.||
