Setup and Configure Lsyncd

I was looking for my options to sync files from Server A to Server B so I found Lsyncd

For the installation

sudo apt update 
sudo apt install lsyncd

We need to create the configuration

sudo mkdir /etc/lsyncd /var/log/lsyncd

Now, create the following file

sudo nano /etc/lsyncd/lsyncd.conf.lua

And add the following configuration

settings {
    logfile = "/var/log/lsyncd/lsyncd.log",
    statusFile = "/var/log/lsyncd/lsyncd.status",
}

sync {
    default.rsyncssh,
    source = "/home/folder/tosync",
    host = "[email protected]",
    targetdir = "/home/folder/destination",
}

If you want to add a custom SSH port and prevent deletion you can do the following:

sync {
    default.rsyncssh,
    source = "/home/folder/tosync",
    host = "[email protected]",
    targetdir = "/home/folder/destination",
    rsync = {
        rsh = "ssh -p 99999",  -- Specify the custom SSH port
    },
    delete = "false"  -- Explicitly disable delete behavior
}
