RMAD -Domain Controller- Backing up to 2 different instances

Hello, 

Presently customer is  using TSE for taking backup of Active Directory and restoration process. 

We are in the planning phase of Quest RMAD rollout. Question is, whether having 2 instances of backup running on DC i.e. one pointing to TSE and another referencing to the Quest RMAD backup path - will this work smoothly? 

Any known challenges that is expected when  DC are having 2 different backup path instances? 

Appreciate your response
