Make a backup Image of Ubuntu Core files
I'm looking for a solution that can make an image of my Ubuntu install (or at least backup everything important) while excluding certain directories.

This is mostly because I have a media center PC that also backs up all of my other PCs/remote servers as well as git, etc. I'm not overly familiar with Linux so setting this up took me forever. If an update or drive failure screwed everything up I'd be set way back. I'd like to be able to make a backup but I don't necessarily care to backup all of my videos/music.
