I don't know what the problem with Time Machine is, but why does it run so darn slow? It tells me there are 3.4 GB to back up, but it will take 19 hours. 19! I could move that many bits over to a 5.25 inch floppy by hand in that kind of time. I have a mid-2012 rMBP running MacOS Sierra 10.12.4, 256g GB SSD encrypted with 145 GB free, 16 GB RAM, a 2TB WDMyCloud NAS connected via cable to my ASUS router, and I'm on the 5G network. There's no way it should take THIS long to back up. Every time my system sleeps or I close it, the backup stops and I have to restart it. Yes, I know I can do this overnight, but this is only 3.4GB. Not a whole lot of data to backup. Thanks for any thoughts.
