I've searched and couldn't find anything related to my issue so forgive me if someone else has already asked. It is my understanding that Time Machine can use a network share provided the host is a Leopard machine? I have a firewire hard drive connected to my iMac which I use for time machine, when I mount the share on my MacBook I can select it in the time machine options and it creates the backup. However, the backup is very different to that created by my iMac. My iMac created /Backups.backupdb/iMac/ if I connect the drive to the Macbook it does the same (obviously with Macbook instead of iMac). However over the network it just created /MacBook_0017f22c7de0.sparsebundle If I open that disk image, it contains the correct structure (/Backups.backupdb/Macbook/) Have I done something wrong or is it suppose to do that?
