1️⃣ What is Multi-User Authorization (MUA) with Resource Guard?
Multi-User Authorization (MUA) is a feature provided by Azure Backup that ensures critical operations (like deleting backups or changing security configurations) require multiple authorized users.
Resource Guard is used to enforce this multi-user approval mechanism, making it harder for a single compromised administrator account to perform destructive actions.
2️⃣ Why Resource Guard is the Best Choice:
Prevents a single point of failure: If an admin account is compromised, the attacker cannot delete backups without additional authorization.
Separation of Duties (SoD): Resource Guard enforces strict role-based access control (RBAC) to ensure that only authorized users can approve sensitive backup operations.
Immutable Backups: Protects your backups from accidental or malicious deletion.
