OneConf helps you to save the state of your computer in the cloud. What does State mean?
By State of a computer, we mean the packages installed in a system. Using dpkg, you can clone your machine. But OneConf provides an easier mechanism.
OneConf can be integrated to your Ubuntu One account. So you can have the same setup in any new machine that you set up
$ sudo apt-get install oneconf
You can configure oneconf with ubuntu one.
