Who cares that files could be already backup in the pool ? Not the 
enduser, the enduser only cares about saving his data and being able to 
get them back. And you as the sysadmin, are a bit more happy, because 
you have a way to control how much data will be backed up. Which will 
help you to evaluate your backup system.

The main problem with my situation is that people have huge amount of 
data stored, and that we only want to provide backup for important ones. 
So we let the user to tell backuppc which directory to backup, and each 
a year we said, we want people beeing able to save 10Gb or 100Gb.

yes, but as already said, such things is a nice feature for the sysadmin 
and not for the enduser.
