Sorry for the delayed reply, but yes, it is extremely difficult to use a single drive for both Mac OS X and Mac OS 9 backup. Primarily, it has to do with the fact that you have already started using Intel Mac operating systems such as 10.6. That has changed the bootable format for the drive to be GUID. It is possible though:
Hope this helps.
I have as many macs as you...lol
I gave up on attempting to use one drive as my master backup system since mounting OS 9 volumes under OS X 10.5 and 10.6 will eventually write info to the volume that OS 9 cannot understand and create various Btree errors when running the OS 9 disk First Aid utility; also I have not found a utility that can defrag any volumes over 190GB under OS 9; so as a general rule of thumb... Use one backup system for all Macs 8.6 thru 9.2.2 and another for OS X Macs. Also keep all OS 9 Volumes to 190GB or smaller and use Norton Speed disk to optimize (defrag).
Hi Jerry, thanks for your reply! Amazing how Macs can multiply...but having a home-based
office and studio and being all Mac-based for 30 years i guess not surprising to accumulate
so many; )
I appreciate your advice...and if you don't mind me expanding on the initial question a bit...
i am a little challenged about a strategy to do some consolidating of content from the various
computers of different eras running various OS's.
I see your point re: one backup system for the OS 8 and 9 volumes... (Carbon Copy Cloner
for example...?) In my current networked setup, Each of my home-office/studio machines is
sharing internet access via an Airport Extreme with a D-Link switch/router expanding the
capacity- so they're all connected whether by Ethernet or Wi-Fi/Airport. This gets into a
networking question and I've always considered it more hassle than it's worth to try and get
my OSX and OS 9 /OS 8 machines to be able to "see" and interact/exchange files with each
other. I've been wanting for a long time to merge/purge duplicate data on the various computers
by offloading everything to a single hard drive and then using some kind of duplicate file find
utility on that 'master' volume.
Ultimately what I was hoping to do was to be able to put a single 1TB HD on the USB outlet of
the Airport and drag/drop stuff from all the machines using that device as the "target" -- the only
catch is that the volumes on the network that are pre-OSX don't seem to have the ability to see -
read/write to that Airport-attached HD. My oldest machine is a Beige G3 w. 8.6 - it is ethernet cabled
to the Airport router and internet connectivity is fine... but i haven't been able to get it to recognize
that Airport HD.
Unless there's actually a way that i'm unaware of, the only route i've considered is to
attach that to the external HD by way of FW or USB - i gave it PCI cards for that capability at
some point but it's kinda flaky in even recognizing any external drive using that type of
direct connection. For starters, I wonder an old G3 would have issues if i'm using a current
generation 1TB HD? I know it has given me an unrecognized device message when i put a
usb thumb drive on it....and for that matter same thing with my Quicksilver G4 with OS 9.
Thanks again for any other thoughts you might have,
I have one more Mac in the basement running Mac OS X Server. I use a school-like setup where ALL user files are on the Server. Any user can log in at any Mac, and individual Macs can get serviced, upgraded, or replaced whenever you like.
They are connected with Gigabit Ethernet switches and cabling. The beige G3 has an Add-on PCI card so it has Gigabit Ethernet as well. The stand-alone Internet Router (provided by Verizon) is not Gigabit-Ethernet capable, but that does not make any difference, as it is not handling the local File Trasfers.
I backup only the Server with Time Machine, and i'm done. The server uses a Mirrored RAID for the User files to increase time-to-repair after a drive failure.
Thanks for the flashback Grant, I prefer your answer...
I used to have a Novell 4.11 Server (in the basement also) with exact same setup, but it was hardware RAID 5 and had mac name space loaded on it; was pretty much the same idea, I used a tape backup to backup the server and thus backed up all 7 mac's by keeping all users data files on the server. Aslo, the IPX client for mac was so fast as compared to appletalk
Gigabit Ethernet gives you "near hard drive" speeds for most file accesses. You can also use a little scripting to put cache files back on the local Macs. I first did a school system (for a school) based on AppleShareIP and 100BaseT Ethernet. Later I moved ot Mac OS X Server 10.2, then up through the versions. Time Machine becomes available in 10.5. I am running 10.6 Server at home now.
Gigabit Ethernet makes it pretty snappy for all but Video editing. And your Ethernet Router does not intervene in Mac-to-Mac transfers, so it can be much slower.
