Backing up multiple computers to one drive

[Van Helsing]

Well, that's not too bad.

I could have one Dedicated GUID Drive to backup and have bootable volumes on there for say, the laptops and server.

But for the bigger, desktop machines, which are a mix of PowerPC and Intel i'll have Sparse Disk Images, as there's no Partition Map to supporting the boot-ability of either type of mac.

Well, you can use Apple Partition Map, but as I said, Leopard strongly discourages users from doing this (unfortunately).

You have said the same thing here two or three times very recently. Could you explain/state just what this "discouraging" from Leopard entails? How is it manifested? I think (but am not sure, running from Tiger just now) that Disk Utility under Leopard still says of the APM option, " ... or to use the disk as a non-startup disk with any Mac."

I guess my question is, is the discouragement in a help file somewhere, or does Leopard shall we say "actively" resist doing this?

[dnanian]

Two obvious things:

- You can't install Leopard to a drive that's partitioned as "APM" on an Intel Mac, which makes archive-and-installs difficult.

- If the drive is partitioned as APM, you can't select it in the Startup Disk preference pane.

Thanks. Sure, I see #1 now. Hadn't really focused on that. Number two I was/am well familiar with.
