Likewise.
Skipping forward to the present, I'm doing normal backups in Bacula to virtual volumes on hard disk. As for offsite/archival backups, using the bacula add-on 'vchanger' and inexpensive high density SATA disks on an eSATA peripheral to act as a virtual tape autoloader magazine is both faster and less expensive than tape.
Bacula is probably better suited to mixing online/tape or fake-tape for offsite, but you can't keep as much online as backuppc without help from ZFS or similar block-level dedup. I doubt if it can match the bandwidth efficiency of backuppc with rsync as the transport (not sure - how does the bacula agent deal with growing files, or big files with small changes?).
