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.

1 - there's 2 things to consider here... A) Your files (documents, photos, etc) B) Everything else (the Windows / Linux mac operating system, applications, your screensaver, printer defaults, etc)
You only need to backup A.
It's up to you if you want / have space for B
But, 1st time, backup everything. Then do item 2 (screw up) big time and do a full restore.
Once you've done that, you're set for life
thx
