I have an imac, and a mybook ethernet hard disk. I'm trying to backup to my new 1.5TB ethernet hard disk. I have a BT 2wire router. All works fine, but the first time machine back up which is about 350G is taking ages. In fact it's taking too long to complete. It takes about 10 minutes per gig. This is really too slow to be useful.
Does anybody have any suggestions?
