System Requirements for Amazon RDS for PostgreSQL

To back up and restore PostgreSQL data on the Amazon cloud application, verify that your environment has the required software and a firewall.

Software Requirements

  • Packages required on access nodes:

    • Virtual Server Agent

    • PostgreSQL Agent

  • Access nodes that you run backup and restore operations on must have one of the following operating systems:

    • Red Hat Enterprise Linux 8.x

    • Red Hat Enterprise Linux 7.x

    • Oracle Linux Enterprise

    • CentOS 8.x

    • CentOS 7.x

    • Windows 2012

    • Windows 2016

    • Windows 2019

    • Amazon Linux 2023 on 64-bit (x86, ARM)


If you have network configuration enabled on the access nodes, before you deploy a Windows or a Linux proxy, configure a firewall on the cloud proxy and on-premises. For more information, see Configuring a Firewall to Install the Virtual Server Agent on a Cloud VM or Instance.

User Account Requirements

For DumpBasedBackupSet, verify that the PostgreSQL instance has a user account with sufficient privileges to perform the following:

  • Perform backup and restore operations of the database objects as part of the subclient content

    The following table illustrates the necessary privileges the user account should have to perform backup and restore operations:


    Privileges PostgreSQL User Should Have





    CONNECTION LIMIT, if set, should at least have a value of 2.

    Initially, the user account credentials are provided during the instance configuration after the installation of the agent. You can change the user account at the instance level.


    You may need to grant other privileges to the PostgreSQL backup user to secure the objects in the database. To know more about database roles and privileges, see PostgreSQL documentation.

Supported PostgreSQL Versions

From PostgreSQL version 10 - 15.x.
