I am facing BARMAN backup issue in EDB postgresql 16 database.
1> For taking incremental backup,I had changed backup_method in barman.conf file from postgres to rsync. Kept any other parameter same
[root@innolx4057 barman.d]# cat my_postgres_server.conf [my_postgres_server] description = "My PostgreSQL Server" ssh_command = ssh dnb-reporting@10.184.40.57 conninfo = host=10.184.40.57 user=barman dbname=dnb-reporting port=5444 #streaming_conninfo = host=10.184.40.57 user=barman #backup_method = postgres backup_method = rsync streaming_archiver = on retention_policy = RECOVERY WINDOW OF 7 DAYS #archiver = on slot_name = barman create_slot = auto
and then tried backup But getting below error
[barman@innolx4057 ~]$ barman cron WARNING: No backup strategy set for server 'my_postgres_server' (using default 'concurrent_backup'). Starting WAL archiving for server my_postgres_server [barman@innolx4057 ~]$ barman check all WARNING: No backup strategy set for server 'my_postgres_server' (using default 'concurrent_backup').

ssh: FAILED (Connection failed using 'ssh dnb-reporting@10.184.40.57 -o BatchMode=yes -o StrictHostKeyChecking=no' return code 255)
archiver errors: FAILED (duplicates: 1)
** Kindly suggest what I am doing wrong here. Reverting from rsync to postgres again running the backup successfully**
