[LAU] how much is contained in the .ardour file

Hi

When working with ardour projects, I'd like to backup the project, in
case I'd like to go back a step in the mixing process. There won't be
added new audio files to the projects from now on. Will it make sense to
store old copies of the .ardour files? Are all information regarding
mixer levels, plugins and cuts in the audio files contained in the
.ardour file?

Regards
