NFS server with Lsyncd in Ubuntu

Make the attached volumes ready

Create folders

sudo mkdir /mnt/upload_disk1sudo mkdir /mnt/upload_disk2sudo mkdir /mnt/backup_disk1sudo mkdir /mnt/backup_disk2

Create partition

sudo fdisk /dev/nvme0n1sudo fdisk /dev/nvme1n1sudo fdisk /dev/nvme2n1sudo fdisk /dev/nvme3n1

Make filesystem

sudo mkfs.xfs /dev/nvme0n1p1sudo mkfs.xfs /dev/nvme1n1p1sudo mkfs.xfs /dev/nvme2n1p1sudo mkfs.xfs /dev/nvme3n1p1

Add fstab entry

sudo vim /etc/fstab

Add the following content

/dev/nvme0n1p1 /mnt/upload_disk1 xfs defaults,nofail 0 0
/dev/nvme3n1p1 /mnt/upload_disk2 xfs defaults,nofail 0 0
/dev/nvme1n1p1 /mnt/backup_disk1 xfs defaults,nofail 0 0
/dev/nvme2n1p1 /mnt/backup_disk2 xfs defaults,nofail 0 0

Setup NFS

Update apt repo

sudo apt update

Install NFS server

sudo apt install nfs-kernel-server

Add configuration for NFS

sudo vim /etc/exports

Add the following content

/mnt/upload_disk1 *(rw,async,no_subtree_check,no_root_squash,no_all_squash)/mnt/backup_disk1 *(rw,async,no_subtree_check,no_root_squash,no_all_squash)

Change permission

sudo chmod 777 /mnt/*

Restart NFS server

sudo systemctl restart nfs-kernel-server.service

Setup backup using Lsyncd

Install Lsyncd

sudo apt install lsyncd

Make directory for configuration

sudo mkdir /etc/lsyncd

Create configuration file

sudo vim /etc/lsyncd/lsyncd.conf.lua

Add the following content

—— User configuration file for lsyncd.
—- Simple example for default rsync, but executing moves through on the target.
—- For more examples, see /usr/share/doc/lsyncd*/examples/–settings
{
    logfile = “/var/log/lsyncd/lsyncd.log”,
    statusFile = “/var/log/lsyncd/lsyncd.status”,statusInterval = 2
}
— Slave server configuration
sync {
       default.rsync,
       delete= false,
       source= “/mnt/upload_disk1”,
       target= “/mnt/upload_disk2”,
       rsync={
                archive = true,
                verbose  = true
             }
}
sync {
       default.rsync,
       delete= false,
       source= “/mnt/backup_disk1”,
       target= “/mnt/backup_disk2”,
       rsync={
                 archive = true,
                 verbose  = true
             }
}

Restart service

sudo systemctl restart lsyncd

Setup firewall rules

sudo ufw allow from 172.32.0.0/24 to any port nfs
