I have been trying to back up my new computer using Time Machine but it's been a problem. I set up a new 3TB USB3 drive as my backup. It starts the process and slows to a halt and tells me it's going to take 2 days to back up 320GB. Any ideas what's going on? I've used time machine on all my other computers and never had this problem.
