backing up to replace internal drive

[bastokyg]

Thanks for the excellent suggestions! I like the Firewire option the best.
I think I may have another solution though -- I've been wracking my brain on this for the past couple weeks:
1. Remove the boot drive from my G4, put it in my blue and white G3 so that I have an OS X bootable G3.
2. Put the new larger drive into the G4.
3. Boot the G3 (that now has the OS X bootable system)
4. Connect the G4 to the G3
5. Make a bootable backup via SuperDuper from the G3 to the G4
6. Now I have a G4 with a larger drive and the exact same system as I had previously.
7. Put the drive from the G3 (that originally came from the G4) into an OWC Firewire enclosure and use it for regular backups of my OS.
