I'm looking to buy a backup drive for two new iMacs. I don't want to do it over a network, but was thinking one drive (say 250GB) split into three partitions: P1: 100GB b/u for iMac 1 P2: 100Gb b/u for iMac 2 P3: 50Gb central storage for both. I was thinking firewire from each computer into one drive, but not sure if this is possible. I'd be using smart update on SuperDuper for the backup. I know most external drives aren't configured for network use - even if it is just for two computers. However I don't have the budget for a proper "network drive". The actual budget is about US$200-250 (AU$250-300) What do you guys think? Is it possible to have a central drive set up like this? I'd rather do firewire so it's bootable should we have any problems (USB is not bootable so that rules out the cheaper WD MyBooks and similar). Cheers!
