(definitive answer) How to backup the mediabay

Hi there
How can i backup the media bay so when i restore or reinstall my system disk , I can get my mediabay working again?

The whole thing is confusing : Is it enough to backup
the .db file which is located on the disk where your tagged sounds are ?

What happens if I move all my sounds ( provided I keep the same architecture ) to another hard disk ? Copying the data bases folder will be enough to Cubase ?

It would be good for steinberg to chime in , with a clear explanation of the process.

Im on OSX Lion.
