  • How to backup your Ubuntu Desktop with DejaDup

    ubuntu Author: Gurujyot_singhTags: , , Comments: 0Published: Mar 04, 2015

    Déjà Dup is a nice graphical wrapper around the command line backup tool duplicity. It hides the complexity of backing up the Right Way (encrypted, off-site, and regular) and uses duplicity as the back end. Déjà Dup does not use cron or similar schedulers. Rather, it starts a program deja-dup-monitor when you log into your session. This keeps track of when you last successfully backed up and will wait until the next scheduled backup.

Ubuntu Linux - humanity towards others

Here at HowToForge we provide you with a wide range of interesting articles and Linux-related tutorials. On this page you will be able to find all Ubuntu-related articles that are spread all over our site through various categories.

Ubuntu is one of the largest, Debian-based Linux operating systems that you can find right now on the market. What makes it special is the fact that its default desktop environment is Unity. The name of this OS is based on the South African philosophy ubuntu that means humanity towards others.

The project is mainly sponsored by the South African Mark Shuttleworth and his UK-based company Canonical Ltd., that provides support and other services to finance itself.

Since Ubuntu is an open source operating system, you can download it free of charge from www.ubuntu.com and you can use it for home or business purposes at all times. The OS comes with numerous pre-installed open source applications, which include programs such as Thunderbird, Transmission, Firefox, LibreOffice and a few games as well.

The great thing about Ubuntu is that it provides you with a built in Software Center from which you can gain access to many applications such as GIMP, Pidgin or a plethora of others. Of course you can use any other APT based package management tool as well. Included with Ubuntu you can even find a Wine compatibility package that allows you to run Windows based apps with ease. Another option is the use of a virtual machine for that purpose.

 

OS with security out-of-the box

One of the things that make Ubuntu stand out is the fact that it comes with a major focus on security right from the start. The OS has a very secure architecture as it allows you to run programs with low privileges that don’t allow apps to make changes to the OS. Moreover, in Ubuntu you can even find an integrated SUDO tool that’s really useful for performing administrative actions. In addition, Ubuntu has most network ports closed from the start in order to prevent hacking. You can even find a built in firewall that provides an even higher security for the OS.

Another major thing about Ubuntu is that, pretty much like many Linux based operating systems, it allows you to run it from a disk image or a live CD without the need of an installation. Something that can be pretty useful to say the least.

As you can see, Ubuntu is one of the most secure operating system on the market, but the fact that it’s open source definitely adds a lot of complexity to it. This is why we are offering quite an amount of tutorials about how you can get the most out of your Ubuntu experience! On HowtoForge you can find tutorials for setting up and running Ubuntu servers and everything that you might need for your daily operations with this amazing Operating System!
