Following comments on another thread, I last Wednesday obtained a 400 Mhz G4 PowerMac from eBay. It isn't ultimately for me, but I will probably end up caring for it if anything should go wrong. I have a 667 Mhz G4 PowerBook. The machine has come without any install discs. The installed OS is OS X v10.0.4. The machine only has a DVD-ROM, but my PowerBook has a CD writer and I have an external firewire hard disk that is larger than the one inside the machine. Even though I doubt that I will keep 10.0 on the machine as there seems to be almost no software that is compatible with it, I would like to create a backup of some sort as a security net. I'm a broadly recent convert from the Windows world and I would feel much happier with such a thing. Is there any way to create an archive of a current disk that can be restored at a later date? I guess what I'm asking is whether there is anything similar to Norton Ghost that I could use? If not is there any other way I could create a backup?
