Configuration:

PowerBook G4 12" 1.5ghz 768mb RAM 60GB ATA
External Iomega 250GB USB2

SuperDuper is too slow. Ive verified that this is not an issue with my USB2 drive running at USB1 speeds; the drive is directly connected to the PowerBook and I have also disconnected any other USB devices.

I get (if Im lucky) 1.5 to 1.6mb/sec with SuperDooper. File copies in the Finder are quick, Backup Data (ProSoft) did an entire duplicate (about 50GB) in about 3 hours. Retrospect 6.1 is reporting anywhere between 190mb/min (3.1mb/sec) to 240mb/min (4mb/sec) on a Duplicate backup.

I am not backing up to a sparse image or other disk image in SuperDuper. This is a disk-to-disk clone.

What is going on here?
