You are separately charged for each service of Database Backup (DBS). This topic describes the billable items and billing methods of 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 that are generated when you use resources during each billing cycle.
|Billable item||Description||Billing method|
|Backup fees||Fees that are charged 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. The backup and restore performance, free quota for data backup, and unit price vary based on backup schedule specifications. For more information, see Backup fees.||
|Storage fees (optional)||Fees that are charged 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. If you configure
a backup schedule to back up data to an Object Storage Service (OSS) bucket or a self-managed
Network Attached Storage (NAS) file system, DBS does not charge you storage fees.
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 that are charged for network traffic generated when you back up data across regions in the ApsaraDB RDS console. For more information, see Enable cross-region backups for an ApsaraDB RDS for MySQL instance.||
|DBS sandbox fees (optional)||Fees that are charged for sandbox instances that you create in DBS. You can use the DBS sandbox feature to restore backup sets to make your backup data available within seconds. For more information, see Overview.||For more information, see DBS sandbox fees.|
