I recently had to erase the HD on my iMac and do a complete restore from my external Time Machine drive. Luckily everything,including programs, were restored to where they were during the last backup. This mishap underscored the importance of having everything backed-up and made me truly appreciate Time Machine. As a result I'm considering adding Time Capsule as a secondary Time Machine drive(in addition to the G-drive I have connected via firewire),to act as a back-up to the back-up. I was wondering if I'd be able to do that if I install TC using the "Bridge to an existing network" option during setup. Would I be able to manage my backups by changing the volume in Time Machine's settings from TC to my G-Force HD, or vice versa? To be clear, i want two full back-up records on seperate drives at any given time. I am accustomed to doing my back-ups manually as I don't want my back-up HD running continuously or every hour or so as is suggested by Apple. My feeling is that my external HD will last longer by not being powered-on 24/7. Another reason why I like TC over simply getting a second external HD is because of the networking capability of TC. I get a very weak signal as it is in my basement and I'm hopeful this will improve streaming to my ps3 and iPhone when I'm downstairs. Cheers,Luis
