edit rsyncd.user file:
vi /etc/rsyncd.user

ignore errors

hosts allow = 66.66.66.66 #listen to client server which use public ip
hosts deny = 0.0.0.0/32
auth users = my_rsync_user_1
secrets file = /etc/rsyncd/rsyncd.user

Next, create init start up script

Setup rsync client
first, of course you must have rsync installed on client server
make rsync password file

| cd /etc
mkdir rsync
cd rsync
touch rsync.pwd
chmod 600 rsync.pwd |
vi /etc/rsync/rsync.pwd
execute this command to start synchronize file to server
1
| rsync -vrtLogp --progress /path/to/directory/to/be/backup/* my_rsync_user_1@[SERVER_IP]::profile_1 --password-file=/etc/rsync/rsync.pwd |
where [SERVER_IP] is rsync server IP
