Google Drive Syncing Folders

With Google Drive's price drop, I went ahead and bought a 1 TB. What's the best way to sync folders between the Google Drive folder on my Mac and the various folders I'd like to backup to Google Drive (e.g. Music, Pictures, Documents, etc.). I want to keep my folders in my Home drive, but have Google Drive backup specific folders without me having to replicate that data locally in my Google Drive folder.

Thanks in advance!
