我正在嘗試配置Barman進行備份。當我做一個barman check replica我不斷收到：WAL存檔：失敗（請確保WAL運輸已設置）
Server replica:
WAL archive: FAILED (please make sure WAL shipping is setup)
PostgreSQL: OK
superuser: OK
wal_level: OK
directories: OK
retention policy settings: OK
backup maximum age: FAILED (interval provided: 1 day, latest backup age: No available backups)
compression settings: OK
failed backups: OK (there are 0 failed backups)
minimum redundancy requirements: FAILED (have 0 backups, expected at least 2)
ssh: OK (PostgreSQL server)
not in recovery: FAILED (cannot perform exclusive backup on a standby)
archive_mode: OK
archive_command: OK
continuous archiving: OK
archiver errors: OK
我使用PostgreSQL 9.6和2.1酒保;我不確定這個問題有人可以幫忙嗎？ 這裏是我的酒保服務器配置：
description = "Database backup"
conninfo = host=<db-ip> user=postgres dbname=db
backup_method = rsync
ssh_command = ssh [email protected]<db-ip>
archiver = on
