The home partition holds all user data and settings. When backing up my home partition it contains a lot of data (the settings) I don't need. So I thought I could create a separate data partition and mount it to ~/Data. That would make my backups smaller and the backup process easier because all my important data is on this partition and nothing else. How can I create and mount such a partition. Is it possible to set this up during the Ubuntu 12.04 LTS installation? Another important thing would be that the places shortcuts in nautilus (documents, music etc.) should point to the directories in my data partition. Is that possible?
Thanks for your time
