Has anyone atttempted to backup both machines to a Hitachi G-Raid with one partition? If they have, was it by direct USB 2.0 wire  using AirPort Express for the Mac Pro and direct fire wire to the iMAC?

 

Any thoughts on this would be appreciated.

    You can't connect a single drive to two pieces of hardware at once.

     

    What you can do is connect it to the desktop, and back up the laptop to the same drive via your network.

     

    There's no reason that won't work, but I'd strongly advise partitioning the drive, so TM on each Mac has it's own, exclusive space.

     

    See Time Machine - Frequently Asked Question #33 for details.

    Thanks for your advice on using Time Machine (TM). I was a little anxious to get this done so-o-o-o- I essentially took the fire wire from the iMAC and connected it directly to the MacPro.

     

    The result was , it created a separate backup on the single partition Hitachi G-Raid drive. As a result , I see both of the backups on the G-Raid whenever I view them from either machine when hooked directly.

     

    I cannot see G-Raid when both are connected as per my original post.

     

    To backup in the future requires hooking up each machine individually and using TM.

     

    My impatience pre-empted waiting for an answer. Will my original question of using AirPort Express work or does the fact that both machines are hooked up at the same time prevent either machine from working with TM?

    To do it that way, yes, but that's not your best bet.

     

    First, having both sets of backups made directly, in the same partition, may present problems later on. See Time Machine - Frequently Asked Question #4 for details.

     

    Second, the inconvenience of switching back and forth means both Macs won't get regular backups.  If you do switch frequently, there's the risk of damaging a port or plug.

     

    Your best bet is to partition the drive.  Continue backing-up the iMac to one partition directly.  Leave the drive connected to the iMac, and back the laptop up to the other partition via your network.   See Time Machine - Frequently Asked Question #33 for details, and #22 for setup instructions.  That way, both will be backed-up hourly, as long as they're awake and the laptop is in range of your network.

     

     

    Will my original question of using AirPort Express work

    No.  You cannot connect a drive to an Airport Express's USB port, only a printer.

    Thanks again. The AirPort Express will now be redirected to the printer or the Stereo speaker system. As for the laptop, I think I will purchase another larger Hitachi (4Tb) G-Raid for backup via network .

     

    My Son will be happy to hear that he inherits a 2Tb drive.

     

    Appreciated your help in this matter.
