My situation, in brief: Last week I installed Leopard to my G4 iMac and SR MacBook Pro, which are networked together with a new AEBS. Because I used Erase and Install, I have not had any of the problems other users have been reporting. On both machines I set up Time Machine to back up to a 250G LaCie external disk attached to the G4 machine via FW400. After direct-connecting with Ethernet for speed while Time Machine built the initial backup of the MBP, I have even been able to run Time Machine incrementals over WiFi with no problems.<P>
But as soon as I installed yesterday's 10.5.1 upgrade, I lost the ability to access the G4's external disk from Time Machine on the MBP. No problem backing up from the G4 itself, but when I selected the external disk in the Time Machine Preferences pane Choose Disk function, it just went right back to Choose Disk as though I had not made a selection.<P>
What I have just discovered is that when I applied the update on both machines, it degraded my admin-level logon to the G4 on the MBP to a Guest logon. Although I can still see and access files on the external disk from Finder on the MBP, Guest level access causes the volume to become inaccessible to Time Machine, even though a normal disk icon still shows as being available for selection. Having a simple message to indicate what the objection was would have saved hours of frustration. I hope this gets fixed in the next update.<P>
The workaround then: from Finder on the MBP in this case, relog onto the remote machine as an admin user as before. Its external volumes will then become available to Time Machine once more.
