Introduction
If you are running an Ubuntu server for your website or application, it is crucial to have a backup strategy in place. A backup ensures that in case of a disaster or system failure, you can quickly restore your server to its previous state. In this article, we will guide you through the process of backing up your Ubuntu server.
As a website or application owner, there are several reasons why you might need to back up your Ubuntu server. For instance, you might accidentally delete critical files, a system upgrade could go wrong, or even worse, a security breach could destroy your entire server.
This article provides an in-depth guide on how to back up your Ubuntu server, including the advantages and disadvantages of different backup methods. We will also provide you with frequently asked questions about backing up your Ubuntu server.
How to Backup Ubuntu Server
1. Use the Built-in Backup Tools
Ubuntu comes with two built-in backup tools: Deja Dup and Duplicity. Deja Dup is a graphical user interface for Duplicity backup system that comes preinstalled with Ubuntu. Duplicity is a command-line tool that provides incremental backups and encryption capabilities.
To use Deja Dup, simply search for it in the Ubuntu Dash and open it. Select the backup location and configuration options, and click “Backup Now.” Duplicity, on the other hand, requires a bit of command-line knowledge to use. Follow the instructions in the official Ubuntu documentation to set up and use Duplicity.
2. Use the Command Line to Backup Your Ubuntu Server
If you prefer using the command line, you can also use the Tar command to create a backup of your Ubuntu server. The Tar command is a commonly used tool in Linux that archives files into a single file.
To back up your entire server using Tar, you will need to log in as root or use the sudo command. Use the following command to create a backup of the entire server:
Command |
Description |
|---|---|
tar -cvpzf /backup/server_backup.tar.gz –exclude=/backup –one-file-system / |
Creates a backup of the entire server, excluding the /backup directory. |
This command will create a compressed backup file at /backup/server_backup.tar.gz. You can change the backup location to any directory of your choice.
3. Use a Cloud Backup Service
Another option to back up your Ubuntu server is to use a cloud backup service. Cloud backup services like Amazon S3, Google Cloud Storage, or Dropbox provide secure and scalable backup solutions.
To use a cloud backup service, you will need to sign up for an account and create a storage bucket. You can then use the command line or a graphical user interface to upload your backup files to the cloud.
4. Use a Backup Plugin for Your CMS
If you are using a content management system (CMS) like WordPress or Drupal, you can also use a backup plugin to create a backup of your Ubuntu server. Backup plugins like UpdraftPlus and BackupBuddy provide an easy and convenient way to back up your website or application.
To use a backup plugin, simply install it on your CMS and configure the backup options. You can then schedule automatic backups or manually trigger the backup process from your CMS dashboard.
5. Use a Backup Appliance
Finally, you can also use a backup appliance to backup your Ubuntu server. Backup appliances are hardware devices that come preconfigured with backup software and storage. They provide a plug-and-play backup solution that requires minimal setup and maintenance.
However, backup appliances tend to be more expensive than other backup methods, so they might not be the best choice if you are on a tight budget.

Advantages of Using the Command Line to Backup Your Ubuntu Server
Using the command line to backup your Ubuntu server provides a lot of flexibility and customization options. You can use the Tar command to create incremental backups, exclude certain directories, or compress your backup files.
Disadvantages of Using the Command Line to Backup Your Ubuntu Server
Using the command line requires some technical knowledge and can be time-consuming, especially for large servers. You also need to manually upload your backup files to a remote location, which can be challenging if you are not familiar with Linux networking.
Advantages of Using a Cloud Backup Service
Cloud backup services provide a scalable and secure backup solution that is accessible from anywhere. They also offer advanced features like versioning, encryption, and granular restore options.
Disadvantages of Using a Cloud Backup Service
Cloud backup services can be expensive, especially if you have a large amount of data to backup. They also require a reliable internet connection and can be slow if you have limited bandwidth.
Advantages of Using a Backup Plugin for Your CMS
Backup plugins for CMS provide an easy and user-friendly way to backup your website or application. They also offer scheduling options and can automate the backup process.
Disadvantages of Using a Backup Plugin for Your CMS
Backup plugins for CMS might not provide a complete backup of your server, especially if you have custom configurations or scripts. They also require some technical knowledge to install and configure properly.
Advantages of Using a Backup Appliance
Backup appliances provide a complete backup solution that requires minimal setup and maintenance. They also offer advanced features like granular restore options and deduplication.
Disadvantages of Using a Backup Appliance
Backup appliances can be expensive and might not fit your budget, especially if you have a small server. They also require some technical knowledge to configure and maintain.
Frequently Asked Questions About Ubuntu Server Backup

3. How can I automate the backup process?
You can use cron jobs or scheduling options in your backup software to automate the backup process.
4. Should I use compression when creating backups?
Compression can save storage space and time when creating backups, but it can also slow down the restore process. It’s up to you to decide whether to use compression or not.
5. How can I test my backups?
You should regularly test your backups to ensure they are working correctly. You can restore a backup to a test server or a virtual machine to test its integrity.
