To back up and restore PostgreSQL data on a Google application, verify that your environment has the required software and a firewall.
Packages required on access nodes:
Virtual Server 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
Note: 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.
