PolarDB Standard Edition includes a free quota for backup storage. When your backup usage exceeds this quota, charges apply based on the amount of storage consumed and how long it is retained.
Free quota
Each cluster gets a free quota for both data backup and log backup. Charges only apply to usage beyond these thresholds.
| Backup type | Free quota |
|---|---|
| Data backup | 50% of your current database storage size |
| Log backup | 100 GB |
Billing rates
Rates vary by region. The hourly price applies to the total backup size that exceeds your free quota.
