Hiya Two questions : I'm running backups with superduper to a Buffalo Linkstation Pro. 1. Can I still carry on doing my work while superduper does a full system backup? Or does this risk corrupting the files? 2. It's very slow, about 3mb/sec (this is via a gigabit cable from the gigabit Powerbook directly to the gigabit Buffalo Linkstation Pro, no routers or hubs in the way) I just ran a test. A direct file copy runs at full gigabit speed, about 30-40 MB sec, but running a backup via SuperDuper runs at 3MB/sec. How can I speed this up? as backing up 80GB takes about 4 hours! Hope you can help.
