postgresql - WAL 存档 : FAILED (please make sure WAL shipping is setup)

Question

我正在尝试将 Barman 配置为备份。当我执行 barman check replica 时，我不断得到:

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

我正在使用 Postgresql 9.6 和 barman 2.1；我不确定有人可以提供帮助吗？这是我的 Barman 服务器配置:

description = "Database backup"
conninfo = host=<db-ip> user=postgres dbname=db
backup_method = rsync
ssh_command = ssh postgres@<db-ip>
archiver = on

barman check 尝试通过断言存档中确实存在某些内容来确认存档设置是否正确。但是，WAL 段通常只有在填满后才会归档，如果您的服务器空闲，则永远不会发生这种情况。

为了解决这个问题，Barman 提供了一个强制段切换的命令，等待完成的 WAL 出现，然后立即将其归档:

barman switch-xlog --force --archive replica
