How Is DDS Backup Data Billed?

All the DDS full and incremental backups are stored on OBS without occupying the storage of your DB instances. DDS 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 Product Pricing Details.

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. As a result, the original backups of the DB instance will be billed.

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