Hi list,Thank you all for your inputs, I am trying pgbacrest with Enterprised DB. Locally pgbackrest works for EDB but when I am trying for remote repository I am facing an issue ( from the remote host to EDB server password less authentication part )Trying to use a remote host as Repo Server I am facing the issue of passwordless authentication(Public key private key).1. From the EDB server I added the user pgbackrest directory and generated ssh-keys and copied the id_rsa.pub to the Repo server (pgbackrest user's .ssh dir with necessary permissions) everything(passwordless auth) working to one side.From the EDB Postgres Advanced Server nodes $ sudo -u enterprisedb ssh pgbackrest@backup-serverThis works from EDB server machine without any issue(password less auth works)2 But from the reposerver$sudo -u pgbackrest ssh enterprisedb@EDB_Server_IP unable to do password less auth( Its asking password for enterpridb@EDB_Server )How to do the passwordless auth from the Repo server to the EDB server for the default "enterprisedb" user of EDB ? ( enterprisedb user doesn't have any home dir I mean /home/enterprisedb, so I am not sure where to create .ssh dir and authorized_keys for passwordless auth )
Please make sure that the passwordless connection is made between both from EDB Server to Repo Server and from Repo Server to EDB Server.
For this you need to generate the ssh keys on both EDB server abd Repo Servers and copy the id_rsa.pub from EDB Server to Repo Server and vise versa.
I hope this helps.
