From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I recommend anyone to do a backup (I haven't always and it bit me). However, if you create separate /home partition you can keep that between re-installs, even re-installs of different distros. And you can also share the same home partition between multiple OSs you might have installed at the same time.
Sharing /home between distros can cause issues though: If one distro's $SOFTWARE is newer that the other distro's, they will still share the same dotfile configuration, and while most software is designed to deal with older configuration/database/etc files, older software many times cannot deal with newer files.
