The data will be never lost during an update: your data is stored in /home directory, and the upgrade affects the other parts of the system. What might be lost are your app settings and your desktop preferences (it didn't happened never when I made release upgrades, through.).

If you are paranoid, backup your important data to an external HDD, disconnect it, and make the upgrade afterwards.

    @khanthegeek Operating without a backup is like walking a tightrope without a net. Definitely NOT Recommended. Regardless, Frantique is correct. – Elder Geek Mar 13 '15 at 16:19
