Well I don't think BackupPC will do what you want directly, but there
are MANY indirect ways of getting there. Since you didn't say I'll
assume you're going to run BackupPC from your Fedora installation
since that's what I'm running, there will probably be some slight
modifications for Ubuntu.

Some options include:
- Setting up your 500GB disk as the backup drive (for Fedora you would
mount it to /var/lib/BackupPC) and rsync'ing your pool to the 1TB
drive for the redundant part.
- Setting up an LVM mirror between the 500GB and 1TB drives which
would take care of the redundancy automatically but you'd be limited
to the size of the smallest disk (500GB).

I'm not enough of an expert to go over each option in detail but there
are plenty of good rsync and LVM how-to's online. I personally like
the second option but if you don't already have a decent understanding
of LVM then it could be a bit daunting.
