    I want to keep a backup of my MBP in case the drive fails, so I don't lose work time. But, I also want a drive I can boot off, so that if the internal drive literally dies I can keep working. So I bought an 80GB backup hard drive.

    Now how do I backup to it so that the backup image boots?

    Oh, and I've dd'd live filesystems before but I don't know that this is consistently reliable, plus the backup drive is 80GB, and my HD is 120GB, so I need to exclude media directories.

    I don't know if this is possible. Windows resets the USB and FireWire busses during bootup, which would cause Windows to lose track of where its bootup files are if it's booting from a drive connected to one of those busses.

    Obviously OSX may handle it differently, though.

    Either way, an image clone done by Norton Ghost should do nicely. It always works for me.

    psync is doing it now. Its not commented or readable, so I coudn't verify its integrity but... it seems credible.

    And its as simple as: sudo psync -d / /Volumes/I<backup>
