Hi,
My dad's 2013 iMac is running Yosemite (10.10.5) and we recently bought him a new 5TB backup drive to replace his previous, nearly full backup drive. The backup drive is connected to a new Orico 10-port USB 3 hub, and both the drive and hub are self powered.
I tried 4-5 backups, the first failed after about 3 hours and subsequent backups failed anywhere between 10 seconds and 3 minutes, consistently. (There was a reboot done after the first backup as well.)
Regarding time...
time machine backup, permissions
