Linux Backup Server Setup

Linux Backup Server Setup

We need to get a Linux backup server (destination server) to run the backup process flawlessly.

For this purpose, we recommend Digital Ocean as a great Linux backup server provider which offers robust service and a SUPER DEAL! $100 FREE Credit if you join via this link: $100 Free Credit

For the backup server, we don’t need high specs unlike the source server which has the email server which needs 2 GB RAM minimum. So, the lowest plan will work as a charm unless you need higher storage. Note that the free trial amount provides free credit up to $100 that must be used within 60 days.

Follow the steps below to get your server:

  1. Click on the provided link: $100 Free Credit, then create an account.

3. You will get the following options to choose and customize your droplet, we chose the basics which are:

Choose an image

Ubuntu 20.04 (LTS) x64

Choose a plan


Choose Image and Plan for Linux Backup Server

CPU options

Regular Intel with SSD


We use now: $5/mo – $0.007/hour (1 GB RAM / 1 CPU, 25 GB SSD Disk, 1000 GB monthly transfer).

If you’re looking for a higher specs, you can go for: $10/mo – $0.015/hour ( 2 GB RAM / 2 CPU, 50 GB SSD Disk, 2 TB monthly transfer).

Add block storage

If you’re okay with the storage that comes with the default plan, no need to add extra storage. In case you want to add more, the cost of 10 GB costs $1.

Choose CPU Options, Budget and Block Storage

Choose a datacenter region

We usually keep the default one. The default one now is San Francisco 3

Choose Password option below. We will change the password later and disable the root access, that’s why it can’t be a security problem for us at the moment.

How many Droplets?

1 droplet

Choose a hostname


Choose Authentication, Droplets Number and Hostname

Add tags

No need to add if you have 1 droplet.

Select Project

You don’t need to select anything if you’ve only one project.

Add backups

No need, as it’s a backup server to backup the data on the source server.

Once done with all the options, click on Create Droplet as seen below:

Add Tag, Choose Project Name and Add Backup Option if Needed

It will take few seconds to create the droplet and once it’s done, it will look like below:

And now the droplet is ready! Note that your droplet will get an IP address as shown below.

4. Now you will need to login to your backup server but first it’s better to save the session in PuTTY and create a pin for it. We’ve explained this before in the SSH Remote Connection from Windows-based Machines article (part d. How to Save, Load, Delete & Manage Sessions).

The username to login is: root and the password is the password you assigned to the server when you created it. It will look like below after first login:

For security purposes, you need to change the password now, follow the hints here: Change Password On Ubuntu.
