What's the speed difference between using 'File copy (Finder-readable)' and 'Restorable (pax-based)'?
Here is a snapshot of some numbers based on a 650MB CD backup of a Flash MX installation, running under 10.3.8 and demonstrating both 'file copy' and 'restorable' mode backup sessions for comparison:
Backup target size: 78.2MB reported by Finder, 2073 files
Test system: PowerBook G4 1.5GHz, 1GB RAM, Impression 2.7
80GB Journaled HFS+ 5400RPM 2.5" drive, 50% full
