Making Backups with the Deja Dup Utility

 Using Deja Dup Video

Why Backup your Data?

Computer drives are very reliable, however they do fail, so it is important to make regular copies of your data - so you can recover your data should the worst happen.

As usual with Linux, there are a plethora of utilities to help you to make a copy of your data: in this article, we are going to look at one of the simplest for Linux newcomers: Deja Dup.

Installing Deja Dup

Deja Dup is a GUI-based front-end for the Duplicity backup library, so you need to ensure that both of these get installed. Some of the bigger distros (-like Fedora 15) provide Deja Dup as part of the standard distribution. If your distro does not provide it as standard, then the best way to install them is via your Software Centre:

Deja Dup in the Fedora Software Centre

It can also be installed via the Command Line using the following commands (-for Debian-based distros):

sudo apt-get install duplicity
sudo apt-get install deja-dup

Note: for Fedora or SuSE, replace "apt-get" in the above by "yum"

Running Deja Dup

Once installed, Deja Dup can be run from the desktop Activities Area by clicking on it's icon:

Configuring which Files to Save

Before you can make a backup, you will need to first tell Deja Dup which files you want to protect. When Deja Dup is run, you will see the initial dialogue display:

To choose the files to save, select the menu option:

Edit → Preferences:

A new window will open up - click on the "Files" tab and use the "Add" and "Remove" buttons to add all the directories/files that you wish to backup:

Backing Up your Data

When Deja Dup is run, you will see the initial dialogue display:
