I purchased the ifixit battery replacement for my mid2012 mbp. Before attempting this project I decided to do a backup (I know, why have I waited 5 years to start backing things up, sorry). I connected a network hard drive (WD/myCloud) 4tb and proceeded on to my first backup. The MBP has a 500gb SDD with about 100gb free. The Time machine has been running for three days now and it says Backing up 26gb of 28gb, those number are slowly increasing. so, it said backing up 15 gb of 18gb yesterday. What’s wrong? this is clearly not working, so before I pull the plug and start over, does anyone know what I am doing wrong? Thanks in advance.
Sounds like a wi-fi connection problem to me. Now the cart before the horse. You need to back it up before going after the connection problem. So I would start over and use a direct ethernet connection. Did you format the WD to GUID or leave it FAT? or MS DOS? Time Machine backup seem to work better on GUID drives.
