WAL replication and Archive command for pgbackrest on same server conf

[KK CHN <kkchn.in@xxxxxxxxx>]

Hi List ,

I am trying to configure the pgbackrest  on a live server ( RHEL9, EPAS16 and Pgbacrest .2.52)  which is having a working   WAL archive configuration  to a standby server in postgresql.conf as follows

1. archive_mod =on

2. archive_level=replica
3. archive_command = 'cp %p /data/archive/%f'  

To do the pgbackrest conf on the same   archive_command   directive (So both the existing WAL configuration as well as my new pgbackrest option both will work smoothly.   how to add an entry  in line 3  ??

archive_command = 'pgbackrest --stanza=Demo  archive-push  cp %p /data/archive/%f '

Please correct me If I am doing wrong in the above line..

Thank you,
