Lsyncd – Live Syncing (Mirror) Daemon.

You can obtain an RPM package from EPEL repository.

Configuration file example:

/etc/lsyncd.conf

settings = {

       log = "scarce",

       logfile = "/var/log/lsyncd.log",

       statusFile = "/var/log/lsyncd-status.log",

       statusInterval = 1 
}

    sync {

       default.rsyncssh,

       source = "/sites/",

       host = "192.168.1.1",

       targetdir = "/data/",

       rsyncOps = {"-zlptgoD", "--delete"}
}

/etc/init.d/lsyncd

Don’t forget to add execute permission:

# chmod 755 /etc/init.d/lsyncd

#!/bin/bash
#
# lsyncd: Starts the lsync Daemon
#
# chkconfig: 345 80 30
# description: Lsyncd uses rsync to synchronize local directories with a remote
# machine running rsyncd. Lsyncd watches multiple directories
# trees through inotify. The first step after adding the watches
# is to, rsync all directories with the remote host, and then sync
# single file buy collecting the inotify events.
