How Is RDS Backup Data Billed?

All the RDS full and binlog backups are stored on OBS without occupying the storage of your DB instances. RDS provides free backup space of the same size as your purchased storage.

The lifecycle of automated backups is the same as that of the DB instance. If you delete a DB instance, its automated backups are also deleted, but manual backups are not. For details, see Deleting a Manual Backup.

For example, if you purchase a DB instance with 200 GB of storage, you can get an additional 200 GB of backup space and will only be billed for backups in excess of 200 GB. The first 200 GB of backup data is free. When the 200 GB storage is used up, the backups will be billed on a pay-per-use basis. For pricing details, see Price Calculator.

If your storage is frozen, it is no longer billed and the free backup space is also unavailable.

If your DB instance is frozen, no free backup space is available and the original backups generated before the instance is frozen will be billed.

• If you unfreeze the DB instance, the free backup space will be restored.
• If you delete the frozen DB instance, the existing automated backups will also be deleted. You need to manually delete the existing manual backups. After all the backups are removed, the backup space will no longer be billed.
