AD backup and Managed service accounts

Good morning,

My question for the forum today and I appreciate any feedback on best practise on this subject. We use Windows server backup to take a system state backup on a domain controller had hosts the fsmo roles.

We have been using historically an admin account to do this with a password that never expires. There are too many security risks now a days to have this kind of set up where a managed services account can be used instead.

My questions are simple ones at this point, can you use Manage services accounts to backup AD via Windows server backup and how can i set this up (if possible).
