Hi @sakura_snow_blossom ,
I haven't prepared the development environment yet so I can't confirm, but is there a possibility that I can get things back to their original state by restoring Active Directory as well? In that case, should I use WindowsServerbackup to back up Active Directory?
Both are yes.
As we all know, much of the Exchange configuration settings are stored in AD. Theoretically, after backing up the Active Directory Server using WindowsServerBackup together, you are likely to restore the Active Directory server back to the original state first. And as long as Active Directory is healthy, you can then be able to recover the Exchange 2013 to its original state as well using the backup.
