I have four domain controllers. I need a backup solution for them. Each DC has a HUGE E: drive for data so I mapped from one DC to another and was using built in Windows backup to backup one server to another. The problem is I can't over write and apparently Windows won't delete the oldest backup on a network drive. So, having four server 2012 R2 DCs, and using only the windows server backup, how can I backup these boxes to one another and over write the backups?
Can I do this from powershell or something? I already tried editing the backup after it's created and I can't add or edit a switch that will make it over write, but I sure do need a solution.
