Also assuming you use backuppc 3.0 or newer, which means it is not
available for me as I am using debian stable packages. (Although, I hear
the next debian stable should be out pretty soon, in which case I'll get
the newer version then :)

In the meantime, I simply doubled the frequancy of the full backups, and
adjusted the max keep values for full backups etc...
