About IOPS The IOPS supported by RDS for PostgreSQL depends on the I/O performance of Elastic Volume Service (EVS) disks. For details, see Disk Types and Performance in the Elastic Volume Service Service Overview.
Due to Elastic Volume Service (EVS) constraints, there can be a maximum of 10 EVS disks with their types being changed at the same time. You may have to wait in a queue when you change your storage type. Procedure Log in to the management console.
Data reliability For details, see What Is EVS? Requires device procurement, primary/standby relationship setup, and RAID setup. Database backup Supports automated backups, manual backups, and custom backup retention periods. Requires device procurement, setup, and maintenance.
