Slow Backup Speed
I have Mac Pro that has bootcamp installed on it and the total space on it with bootcamp installed is 163.86 GB and I am trying to back it up to a 8TB external hard drive that is under the format Mac OS Extended (Journaled). The Operating System is MacOS Sierra. The problem is it's taking too long to backup to the external hard drive. I started the backup around 6:30 am come back 5 hours later and its not done and the estimated time till its done is 19 hours. Why is it taking so long to backup my entire Mac that has less then 1TB on it? I am not sure if it matters or not but when I backup my Parallels Virtual Machine which the file size of it is 1.22 TB it only takes 3-5 hours to back up. Why does it take longer to backup my entire Mac when its smaller then my Parallels Virtual Machine? Can someone please help me out here? Thanks.
