If I missed the solution to this in the forums, I apologize in advance. I have been searching these forums and Google all afternoon to find a solution to this problem. If this is addressed elsewhere, please be kind enough to post a link.

Network - Mac XServe and managed client all running the latest updates. Managed settings are the mobile account with manual home sync, login message and display and SUS.

On the server, I set up the /Volumes/Server HD/Backups directory in Server Admin and checked the box to make it a Time Machine destination as the instructions stated.

On the client, I ran the command so that the network volume would show up (defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1) and I am able to select the disk.

When I selected the disk initially, it told me my ID did not have permission to read/write/append to the network volume. So in Server Admin, I added my network ID with Read/Write access in the ACL section. After doing this, I can select the disk and start the backup. It acts like it is going to work, then I get the following error:

+Time Machine could not complete the backup.+
+The network backup disk could not be accessed because there was a problem with the network username or password.+

+Open Time Machine preferences to select the network backup disk and re-enter the correct username and password.+

I have spent the afternoon trying to figure this out. Is there something simple I'm missing and making this more difficult than it has to be?

Thanks in advance for any ideas you can give. I will mention this is my first XServe to administer, so if I'm making this harder than it has to be, that's why.

Numerous, Mac OS X (10.6.3)

    I have the same issue, but with a WD mybook 1TB NAS drive. It works for a day or two, then fails. Re-entering the username and password corrects it for a day or two, and it fails again. Has been a problem since the NAS was installed. I never used Time Machine before that.

    Hi Erik,

    If Time Machine is backing up to a network volume you should be able to do the following.

    1) Setup your time machine share on the server (remember that it's a good idea to keep this off the system disk incase you run out of space)

    2) On the top menu bar or from System Preferences in 10.5 or 10.6 click on the Time Machine icon or Open Time Machine Preferences

    3) Click "Select Disk" and choose the time machine volume that should be shared over the local network and viewable. You should enter the administrator username and password for the server when prompted and that should be it.

    We run 2 old Xserve Raids as Time Machine backup destinations over our network via a 10.6.3 Server. So far we haven't had any issues with it in the 10 months since I set it up and backup quite a few 10.5 and 10.6 machines.

    Hope that helps
