Thank you very much, John. That's exactly what I need and I think I 
understood what is the hole idea here. I'll check the manuals for 
understanding what those options mean. Tomorrow morning I'll do my 
tests. If I have additional doubts, I'll ask you. I'm not sure if I 
would need to recycle the backup file regularly, manually, or creating 
new volumes...

Thank you for your explanations.

Rodrigo.
