So I'm going to be buying a Mac next week - whether this rumored update drops or not - and am trying to figure out what else I'll need to buy. I had a drive drive on me in a PC a couple years ago, and I lost about 2 years worth of pictures, because I wasn't as religious about backups as I should've been. After that though, I've been doing nightly backups to a couple of large network drives I bought (each is 1TB mirrored, which backs up to an external USB drive weekly for a third layer of paranoid redundancy). I want to make sure I have a backup system in place for my Mac when I get it (or at least shortly thereafter) Ideally, I'd like to just keep using my existing storage devices, as I'm only using about 60% of the space across them so far. The catch is that they use the EXT3 file system. Does anybody know if Macs can read/write to that? Or am I going to run into issues? I'd really like to avoid buying a Time Capsule if I can Thanks in advance.
