Time capsules are so expensive, and I don't need another wireless base station. But the prospect of wireless automated backups is really enticing to me. Is it possible to get the same functionality from anything else? They make external hard discs that you plug into the ethernet. I haven't researched these in a long time, and my father says they used to be very slow. Would something like that work? What if there were two Macs, and one of the Mac just sat in one place, always on, sharing one of its hard discs. Could that stationary Mac be set as the target for backups by the other Mac and used with all the convenience of a Time Capsule? Now what if the stationary computer were a Linux box instead of a Mac. Could that setup be made to work? I plan to set up a stationary Linux box as a server, so I really hope the answer is yes, and I can use it for backups too.
