Lion introduced a "feature" that will put time machine backups on your local disk if your primary time machine drive isn't available. I'm not sure the details about how often it writes to your local drive, but I don't know that you can't delete it easily.

This short guide will show you how to disable local time machine backups.

1

You can open Terminal but navigating to Applications->Utilities in Finder.

Or, you can type cmd + spacebar which will open Spotlight. Then, search for Terminal.

2

There is a handy feature on your mac called tmutil that stands for Time Machine Utility. To disable the local backups, in Terminal type tmutil disablelocal and you should see your local backups are gone.

3

In order to read more about tmutil open Terminal and type man tmutil which will open the manual for tmutil. Here you can find out to restore local backups if you'd like.
