After countless hours of configuring, tweaking, installing new applications onto your Ubuntu system, the last thing that you want to do is to reformat and start everything all over again. Remastersys is here to save you all this trouble. Remastersys is a simple and easy to use application that allows you to easily clone and backup your Ubuntu system so that you can quickly restore your computer to its previous state in the event that it crashes.

There are two thing that Remastersys can do:

1. To do a full system backup, including all installed applications, their settings and your personal data, to a live CD or DVD. You can use this live CD or DVD to restore your system or to install it in another computer. You can also bring it around and use it everywhere as a Live CD.
2. To create a custom distributable copy of your current Ubuntu system and share it with your friends.
