You really need an application aware backup with AD.
Option 1: Additional backup-software
Option 2: Combine Windows-Backup with XOA

Option 3: Install a new DC
@jsawyer77 Did you follow the documentation when building XO? If not, then what process did you use?
Also, check to see if libvhdi-utils is installed and which version.
