Configure rsyncd service on copy target Host, refer to here.
This example is based on the environment like follows as the link above, and additionally install lsyncd on copy source Host.

+----------------------+          |          +----------------------+
|    [dlp.srv.world]   |10.0.0.30 | 10.0.0.51|  [node01.srv.world]  |
|        lsyncd        +----------+----------+        rsyncd        |
|     /home/work/*     |   ------------->    |     /home/backup/*   |
+----------------------+      live copy      +----------------------+

root@dlp:~ #

pkg install -y lsyncd

root@dlp:~ #

vi /usr/local/etc/lsyncd.conf

settings {
  logfile    = "/var/log/lsyncd.log",
  statusFile = "/var/log/lsyncd.status",
  statusInterval = 1,
  maxProcesses = 2,
  insist = 1,
}

sync{
  default.rsync,
  delay = 0,
  # specify copy source directory
  source="/home/work/",
  # specify copy target Hostname or IP address and target name: (set in rsyncd.conf)
  target="node01.srv.world::backup",
  # specify exclude file list
  excludeFrom="/usr/local/etc/rsync/exclude.lst",
  rsync = {
    archive  = true,
    compress = true
  },
  delete = true
}

root@dlp:~ #

service lsyncd enable

lsyncd enabled in /etc/rc.conf
root@dlp:~ #

service lsyncd start

Starting lsyncd.
