RDS uses Elastic Volume Service (EVS) disks for storage. For details, see Elastic Volume Service Service Overview. The RDS backup data is stored in OBS and does not occupy the database storage space.
The supported IOPS depends on the I/O performance of the Elastic Volume Service (EVS) disk. For details, see "Ultra-high I/O" in Disk Types and Performance of the Elastic Volume Service Service Overview.
General-Purpose DB Instances 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.

Connecting to a DB Instance from a Linux ECS over a Private Network You can connect to your DB instance using a Linux ECS installed with a PostgreSQL client over a private network. You can use the PostgreSQL client psql to connect to your DB instance over a Secure Sockets Layer (SSL
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.
What Should I Do If an ECS Cannot Connect to an RDS for PostgreSQL Instance Through a Private Network? Perform the following steps to identify the problem: Check whether the ECS and RDS for PostgreSQL instance are located in the same VPC. If they are in the same VPC, go to 2. If they

Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), can all be shared within a given region.
How Can I Back Up an RDS for PostgreSQL Database to an ECS? You can back up data to an ECS the same way you export SQL statements. The ECS service does not have restrictions on the types of data to be backed up as long as the data complies with local laws and regulations. You can
Resilience RDS for PostgreSQL uses EVS disks to store data, providing three-copy storage and 99.9999999% data durability. It also provides features like cross-region replication and intra-AZ anti-affinity, to guarantee reliability and availability of your instances.
