Backup your data in Linux with Deja Dup
Welcome to Déjà Dup, the best backup gem I have ever seen.
Note that this article, which started as a comprehensive piece about this program, turned out to be quite short. The reason? Simple: the program is disarmingly easy to use and to explain. This article could be called "Déjà Dup: the definite guide".
Running Déjà Dup
If you are using Ubuntu 11.10 or later, you don't have to install Déjà Dup. In fact, you don't even have to run it: it's straight in the configuration settings of your Ubuntu system.
