报错总结 rsync推送问题

报错原因：客户端推送/data到服务端
客户端显示正常
服务端/backup下空的

客户端发送
[root@nfs01 /data]# rsync -avz /data rsync_backup@172.16.1.41::backup
sending incremental file list
data/
data/1.txt
data/10.txt
data/2.txt
data/3.txt
data/4.txt
data/5.txt
data/6.txt
data/7.txt
data/8.txt
data/9.txt

sent 610 bytes  received 218 bytes  1,656.00 bytes/sec
total size is 0  speedup is 0.00
服务端接受
root@backup ~]# ls /backup/
空的
服务端各种配置没毛病
[root@backup /backup]# ls -ld /backup/

客户端也没毛病

 export RSYNC_PASSWORD=oldboy

俺也不知道为啥
传过去是空的
解决方法
删除服务端/backup目录
rm -rf /backup
重新创建/backup
mkdir -p /backup
授权
chown rsync.rsync /backup
俺也不知道为啥然后在客户端推送就能通
