Creating Backup files in Windows Vista

Hello Techyv!
I want to know how to create backup files?
I am using Windows Vista Premium.
I have the numbers of some important files, that have been saved onto my documents and need to be backed up for the meantime.
But the problem is, I don't know how to create a backup file. As I click the backup/restore wizard, I don't know which option I need to click.

This wizard helps you back up or restore the files and settings on your computer.
If you prefer, you can switch to Advanced Mode to change the settings for backup or restore. This option is recommended for advanced users only.
I want a concise instruction, in order for me to understand the pattern easily. I know you guys have broad knowledge about this matter. So please feel free to post your ideas!.
Thank You,
Curtl.
