10.5: Repair Time Machine after logic board changes
I am planing to something which seems will run into this very problem. I am getting a new Mactel computer. I am running Leopard on a PPC machine off an external Firewire drive. I was planning to just move the external drive between the computers which will be housed at different locations and run the same system on both computers, thus keeping them in sync with the least hassle. But from this thread it appears that I will have problems with Time Machine because I will be using two different computers which I presume will have different MAC's. Does this mean that I will either just have to abandon Time Machine altogether; or use two separate Time machine volumes, one for each computer and all the needless duplication of files that this will entail?

TM is tightly coupled with a specific Mac. If you have two Macs and one External HDD the one HDD can be used by both Macs but there will be two TM folders created - one for each Mac. TM will know which one is associated with its machine so there's no worry there.

Actually, as of Leopard, it's quite easy to build a system that works for both architectures and has a complete installation.

What happens when you run Software Update, or any kind of installer or other updater, on such a universal drive? Can we assume that all updaters and installers will be available in a universal version, and if so, that Software Update will automatically install a universal version? I'd be concerned that, when the drive was connected to an Intel Mac, that at least for some updates, at least in Software Update, Intel-only code would get installed, with no option given to the user to make a choice, and the equivalent/reverse would happen when the drive was connected to a PPC Mac. If this is so, this would still argue for the use of two separate volumes on an APM-formatted drive, one for Intel OS X, and one for PPC OS X.

You should be able to have a single Time Machine backup (as per your comment below) but you may want to consider having a separate backup at both locations - that was you'll always have an "off-site" backup that's current. |
