Hi,
I have a query about file transfer while taking backups. I understand 
that backuppc uses de-duplication i.e. only a single copy of the file is 
stored even if multiple copies of it exist on different machines. 
However, what I would like to know is when a file is transferred after 
being backed up once. Is it during the next full-backup? Is it after a 
certain duration has elapsed? Or is it that once a file is copied it is 
never transferred again (even for full-backup) unless it is changed?

On a side note, backuppc has so far proved to be the best disk based 
backup solution I have come across. I was so impressed with it that I 
even configured it on dd-wrt based router 
https://rahul.amaram.name/blog/2009/12/28/backuppc-lighttpd-dd-wrt . 
Keep up the great work.

Looking forward to a response.

Regards,
Rahul.
