They use to run at about 1 gb/s which was nice, but they are running at about 100mb/s now. It use to take 8 hours, and now it takes 24+. We were having trouble with bad hardware, but we finally got it all replaced with the same models, just new. At first no backups were working for some reason, and I tried all the software troubleshooting I could. I finally reinstalled the software, saving the folders and data and reinstalling the software and put it back. When we got a new tape drive, because it was clunking, it ran 1 backup once, at 500mb/s. Then it stopped, the cable went bad. I tried to update firmware and errors came up saying check the cable. Replaced that and now communication is back up. However its very slow.....what could be the cause? I updated the firmware, and restarted the machine. Remote service is disabled. Its updated through windows and I am running a liveupdate right now. Any suggestions?
