I'm contemplating doing the following. Setting up Time Machine on my Mid-2007 24" iMac (either to a Time Capsule or a Firewire 800 drive) and then configure my 1Ghz eMac running Tiger to regularly rsync its hard drive to a location on the iMac. The result would be that I could go back in time via Time Machine on the eMac as well, via the iMac. Anyone else try this? Do you know of a better way to backup the eMac while keeping it on Tiger? It seems every mac backup article I find is geared toward making bootable backups via Carbon Copy Cloner and SuperDuper!, etc. While a bootable copy would be nice, I'm far more concerned about having the last X revisions of a file, or having going back in time to get a file I might have unknowingly deleted. Regularly cloning my HD to an external disk via SuperDuper! for example wouldn't provide this, but Time Machine does.
