Backup Configuration
• When you order an RDS-PostgreSQL instance, the data storage space and backup storage space are configured at 1:1 by default.
• During use, you can expand your data storage space and the backup storage space respectively. The total amount of the backup storage space must be greater than or equal to that of the data storage space.
Billing Mode
• If you directly delete the frozen instance, the original automatic backups are also deleted simultaneously, and the backup space will no longer be charged for automatic backups.
