Using Mezzo to archive and restore

[blankpro]

I am using Mezzo to archive to AIT tape.

My question is for those who are archiving projects, and then restoring them later, adding changes, and so on.

If I archive by dragging the project over, that's great. owevber, in my woirk i create multiple projects of the same audio files - various mixes, versions, etc. How does this work? Does Mezzo make multiple backups of my audiofiles? Or does it
'look up' the files in the project that is created?

The reason for this is obvious - I can't afford multigigs of projects for each song I make.

How do you do it?

Does the original project become the basis for all others? Do you need to drag each ptools project over each time into the folder?

Thanx in advance for the insight....
