Ghost is not designed for small backups.
Just use Robocopy (it's a standard part of Windows 7 and easily downloadable if you use an older O/S)
This synchronises source and target and is extremely fast with LOTS of command line options.
I tend to use:
Robocopy c:\folder d:\folder /E /PURGE /XJ /R:1 /W:1
This synchronises C:\folder to D:\folder, /E to include subdirectories, /PURGE to remove content in target that has been removed in the source, /XJ to avoid junction points, /R:1 - allow one retry on a read error /W:1 - wait one second between retries.
You can also exclude files and directories - eg: /XF pagefile.sys /XD "System Volume Information"
