Free quota

PolarDB offers a free quota for backup storage. After the quota is exhausted, you are charged based on the size and retention period of backup files in intra-region backup scenarios. In across-region backup scenarios, in addition to the backup storage fee, a cross-region network traffic fee is also generated.

Billing rules

Backups include level-1 backups, level-2 backups, and log backups. Prices vary based on the backup type.

• The free storage quota for level-1 backups is 50% of the cluster storage usage. After the free quota is exhausted, you are charged based on the additional storage usage and retention period of the level-1 backups. The following table describes the prices.

  Storage type	Region in the Chinese mainland	China (Hong Kong) and regions outside China	Billing method

  Storage type	Region in the Chinese mainland	China (Hong Kong) and regions outside China	Billing method
  PSL5	USD 0.000464 per GB-hour	USD 0.000650 per GB-hour	Storage fee per hour = (Total size of level-1 backups - Free quota) × Unit price per hour For example, a PolarDB for PostgreSQL cluster deployed in the Chinese mainland uses the PSL5 storage type. If the total size of level-1 backups (snapshots) is 700 GB and the cluster storage usage is 1,000 GB, the level-1 backup storage fee per hour is USD 0.0928. The fee is calculated by using the following formula: [700 GB - (1,000 GB × 50%)] × USD 0.000464 per GB-hour = USD 0.0928. Note For information about how to view the size of level-1 backups, see FAQ.
  PSL4	USD 0.0003 per GB-hour	USD 0.000433 per GB-hour

• You can implement level-2 backup across different zones in the same region or across different regions. In intra-region backup scenarios, you are charged based on the size and retention period of level-2 backup files. In cross-region backup scenarios, in addition to the level-2 backup storage fee, a cross-region network traffic fee is also generated.

    Region in the Chinese mainland	China (Hong Kong) and regions outside China	Billing method

    Region in the Chinese mainland	China (Hong Kong) and regions outside China	Billing method
    USD 0.0000325 per GB-hour	USD 0.0000455 per GB-hour	Storage fee per hour = Total size of level-2 backups × Unit price per hour For example, a PolarDB for PostgreSQL cluster is deployed in the Chinese mainland. If the total size of level-2 backups is 1,000 GB, the level-2 backup storage fee per hour is USD 0.0325. The fee is calculated by using the following formula: 1,000 GB × USD 0.0000325/GB/hour = USD 0.0325.

  • Billing rules for cross-region level-2 backup

    Billable item	Region in the Chinese mainland	China (Hong Kong) and regions outside China	Billing method

    Billable item	Region in the Chinese mainland	China (Hong Kong) and regions outside China	Billing method
    Level-2 backup storage	USD 0.0000325 per GB-hour	USD 0.0000455 per GB-hour	Storage fee per hour = Total size of level-2 backups × Unit price per hour + cross-region network traffic fee For example, a cross-region level-2 backup is performed between regions in the Chinese mainland. If the total size of level-2 backups is 1,000 GB and the consumed cross-region network traffic is 500 MB, the level-2 backup storage fee per hour is USD 0.0691. The fee is calculated by using the following formula: 1,000 GB × USD 0.0000325/GB/hour + 500 MB/1024 × USD 0.075/GB = USD 0.0691.
    Cross-region network traffic	For information about the cross-region network traffic fees, see Network traffic fees.

    Note

    • Cross-region backup is billed on a daily basis. In this example, the daily prices are converted into hourly rates for convenience.

    • Fees for cross-region backup are recorded in Data Disaster Recovery bills.

• You can implement log backup across different zones in the same region or across different regions. In intra-region log backup scenarios, you are charged based on the size and retention period of log backup files. In cross-region log backup scenarios, in addition to the log backup storage fee, a cross-region network traffic is also generated.

    Region in the Chinese mainland	China (Hong Kong) and regions outside China	Billing method
    USD 0.0000325 per GB-hour	USD 0.0000455 per GB-hour	Storage fee per hour = (Total size of log backups - 100 GB) × Unit price per hour For example, a PolarDB for PostgreSQL cluster is deployed in the Chinese mainland. If the total size of log backups is 1,000 GB, the log backup storage fee per hour is USD 0.02925. The fee is calculated by using the following formula: (1,000 GB - 100 GB) × USD 0.0000325 per GB-hour = USD 0.02925.
