Changing the Backup Method

Scenarios

RDS for PostgreSQL allows you to switch between physical backups and CBR snapshot backups. Compared with physical backups, CBR snapshot backups provide faster backup and recovery at a similar cost. If your instance has terabytes of data, use CBR snapshot backups.

Constraints

• To change the backup method in certain regions, submit a service ticket.
• For details about the constraints and billing of physical backups and CBR snapshot backups, see Configuring Same-Region Backup Policies.
• If the storage space exceeds 4,000 GB, the backup method for the instance is automatically set to snapshot backup and cannot be changed.

2. Click in the upper left corner and select a region.
3. On the Instances page, click the instance name to go to the Summary page.
