Hi horix,
CCCloner will do it. It allows you do make a disk image (with the option of not saving some items on the drive) and restore everything back is it was. I just had the chance to try all this out after I got a new (used) 1.25 G4 dualie 10 days ago. After getting the new computer setup with all my software, mail, settings and me replacing the former administrator of the machine, I saved it all as a 19 GB disk image on a second hard drive from my original machine. Also, I tried saving the disk image (chose ASR option - apple software restore) in compressed segments sized to fit a DVD and wound up with 3 segments of about 4.5 GB. I saved these as data files on 3 DVD's. So for the grand test, after wiping the QS 733's drive clean, I copied the 3 image files from the DVD's to a folder on a second hard drive. Then I clicked on the first segmented image and the 3 of them assembled into a single full image of the new computer's drive. Then I used CCCloner to copy this image of the G4 dualie to the pristine drive on the 733. It seemed to work fine, but on booting it would only get to a grey screen with an apple icon in the middle that looked like the side of the computer cases. I tried Disk Warrior and TechTool. Then I tried my first fsk attempt, but I cannot remember exactly how that went, but it did not help. Anyway, what did work is to do an "archive and install" of the system software after booting from a system disk. What I eneded up with was a seemingly very good clone of my new computer on the old one. I ran a bunch of the software and it worked just fine.
For me, this is VERY cool - I now have the new computer setup saved on 3 DVD's as the "fallback" and will backup data files from that point on. Of course I also have "final backups" of the first computer's data files as well, but it's nice knowing that I will not have to manually install and setup the core programs on the machine, ever.
Hope this helps!
