There was a technical discussion of the protocol used for networked time machine backups on the apple support pages but I can't find it back. Basicaly TM was designed to be local first, and adapted to also work over ethernet afterwards, but doesn't properly recover when you have failures (i.e. corrupted data or lost connection) at the wrong timing during the backups. From memory the network protocol changed one or two years ago to be more reliable, but the fundamental assumptions seem to have remained. That's why it's advised you do at least your first backup with a wired connection for instance.
