So you think you're a Leopard expert? Know much about Time Machine? I'm on the edge of moving to Leopard, and Time Machine is the main motivation. Actually, backups are the main motivation - something I'm only doing sporadically now - but as my My Pictures directory is spilling out over and filling up my external 500gb drive, it's starting to get a little scary. So - here are my Time Machine questions: 1 - (Easy) - Can you use Time Machine to back up and keep track of changes on an external (USB 2 or NAS) drive? That is, the external drive is an 'active' drive (I realise I'd need a second drive for TM). 2 - Can the Time Machine drive be connected through the network (i.e. my current drive is sometimes connected by USB or through the ethernet cable)? It would be great to come into the office and have time machine working automatically, whether the drive is connected directly or not... OR would I need to have it connected to an actual (2nd) computer running Leopard/TM that's connected to the network? (I read something about that on apple.com). 3 - Does TM have the ability to use two separate HDs for backups? i.e. Is it possible to have two NAS drives (one at home, one at the office) and have TM keep up to date backups in both places (i.e. a nice redundant backup scheme!?) In writing this, I realize most of my questions are related to backing up through the network on a relatively 'dumb' network attached drive... The reality is that I've got a MBP with an external drive that I'm currently using for photo storage, and I'd love to be able to make backups "just work". My thought is that I could keep all the 'negatives' on that drive, and anything 'in work' on my MBP's internal drive, and TM should be able to keep track of everything... So, can anyone speak to TM's ability to handle this kind of thing? Thanks for your thoughts!
