What is authorative and non authorative restore mode.

Question

Accepted Answer

Authoritative restore mode is used to restore the entire Active Directory while non-authoritative restore mode is used to restore individual objects.

Authoritative restore mode restores the entire Active Directory to a specific point in time and marks it as the current version.
Non-authoritative restore mode restores individual objects from a backup and allows replication to update the restored object.
Authoritative restore mode is used when the entire Active Directory needs to be restored due to a major failure or corruption.
Non-authoritative restore mode is used when a single object needs to be restored without affecting the rest of the Active Directory.
In non-authoritative restore mode, the restored object will be updated with any changes made since the backup was taken through replication.
