Server 2012 R2 Backups Are Slow
As per this post, I have the same issue. I'm using Bitdefender internet security 2015 and my last backup took 3 days, it wasn't even that large only 20GB on gigabit lan.
I have searched and tried all suggestions and the only one that works is disabling the bitdefender firewall.
It would be nice if the previous thread had the solution.
